Moni kwa owerenga mabulogu athu! Tikudziwa kale - zolemba zanga zachingerezi zidawoneka pano zitamasuliridwa ndi mnzanga wokondedwa . PanthaΕ΅iyi ndinaganiza zolankhula mwachindunji ndi omvera olankhula Chirasha.
Pachiyambi changa, ndinkafuna kupeza mutu womwe ungakhale wosangalatsa kwa omvera ambiri ndipo umafunika kuulingalira mwatsatanetsatane. Daniel Defoe ankanena kuti imfa ndi misonkho zikuyembekezera munthu aliyense. Kwa ine, nditha kunena kuti injiniya aliyense wothandizira adzakhala ndi mafunso okhudza ndondomeko zosungira malo (kapena, mophweka, kusunga). Ndinayamba kufotokoza momwe kusungirako kumagwirira ntchito zaka 4 zapitazo, monga injiniya wamkulu wa msinkhu woyamba, ndipo ndikupitiriza kufotokoza tsopano, kale monga mtsogoleri wa gulu lolankhula Chisipanishi ndi Chiitaliya. Ndili wotsimikiza kuti anzanga ochokera ku gawo lachiwiri komanso lachitatu lothandizira amayankhanso mafunso omwewo nthawi zonse.
Mwachidziwitso ichi, ndinkafuna kulemba chomaliza, mwatsatanetsatane momwe ndingathere, omwe ogwiritsa ntchito olankhula Chirasha amatha kubwerera mobwerezabwereza ngati bukhu lofotokozera. Nthawiyi ndi yolondola - mtundu wazaka khumi zomwe zatulutsidwa posachedwa zidawonjezera zatsopano pazoyambira zomwe sizinasinthe kwa zaka zambiri. Cholemba changa chimayang'ana kwambiri pamtunduwu - ngakhale zambiri zomwe zidalembedwa ndizowona m'matembenuzidwe am'mbuyomu, simupeza zina zomwe zafotokozedwa pamenepo. Pomaliza, ndikuyang'ana pang'ono m'tsogolomu, ndikunena kuti kusintha kwina kumayembekezeredwa mumtundu wotsatira, koma tidzakuuzani za izi nthawi ikadzafika. Choncho tiyeni tiyambe.
Ntchito zosunga zobwezeretsera
Choyamba, tiyeni tiwone gawo lomwe silinasinthe mu mtundu 10. Ndondomeko yosungira imatsimikiziridwa ndi magawo angapo. Tiyeni titsegule zenera popanga ntchito yatsopano ndikupita ku Storage tabu. Apa tiwona parameter yomwe imatsimikizira nambala yomwe mukufuna kubwezeretsanso:
Komabe, ichi ndi gawo chabe la equation. Chiwerengero chenicheni cha mfundo chimatsimikiziridwanso ndi njira yosunga zobwezeretsera yomwe yakhazikitsidwa pantchitoyo. Kuti musankhe izi, dinani batani la Advanced pa tabu yomweyi. Izi zidzatsegula zenera latsopano ndi zosankha zambiri. Tiyeni tiwerenge ndikuwalingalira mmodzimmodzi:
Ngati mutsegula njira 1 yokha, ntchitoyi idzagwira ntchito "zowonjezereka kwamuyaya". Palibe zovuta pano - ntchitoyi idzasunga chiwerengero chodziwika cha malo obwezeretsa kuchokera ku zosunga zobwezeretsera zonse (fayilo yokhala ndi VBK yowonjezera) mpaka kumapeto komaliza (fayilo yokhala ndi VIB yowonjezera). Pamene chiwerengero cha mfundo chidutsa mtengo wokhazikitsidwa, chowonjezera chakale chidzaphatikizidwa ndi zosunga zobwezeretsera zonse. Mwa kuyankhula kwina, ngati ntchitoyo yakhazikitsidwa kuti isunge mfundo za 3, ndiye mwamsanga pambuyo pa gawo lotsatira padzakhala mfundo za 4 pa malo osungiramo zinthu, pambuyo pake zosunga zobwezeretsera zonse zidzaphatikizidwa ndi kuwonjezereka kwakale kwambiri ndipo chiwerengero chonse cha mfundo chidzabwerera. 3.
Kusunga kwa "reverse incremental mode" (njira 2) ndikosavuta kwambiri. Popeza mu nkhani iyi latsopano mfundo adzakhala zosunga zobwezeretsera wathunthu, kutsatiridwa ndi unyolo otchedwa rollbacks (mafayilo ndi VRB kutambasuka), ndiye kuti ntchito posungira ndi kokwanira kungochotsa akale rollback. Zinthu zidzakhala zofanana: mwamsanga pambuyo pa gawoli, chiwerengero cha mfundo chidzapitirira mtengo woikidwiratu ndi 1, pambuyo pake chidzabwereranso ku mtengo womwe mukufuna.
Chonde dziwani kuti ndi njira yosinthira-yowonjezera muthanso kuloleza zosunga zobwezeretsera nthawi ndi nthawi (njira 4), koma izi sizisintha kwenikweni. Inde, malo obwezeretsa athunthu adzawonekera pamndandanda, koma tidzangochotsa mfundo zakale kwambiri imodzi ndi imodzi.
Pomaliza, tifika ku gawo losangalatsa. Ngati muyambitsa zosunga zobwezeretsera, koma kuwonjezeranso yambitsani zosankha 3 kapena 4 (kapena zonse nthawi imodzi), ntchitoyi iyamba kupanga zosunga zobwezeretsera nthawi ndi nthawi pogwiritsa ntchito njira "yogwira" kapena yopanga. Njira yopangira zosunga zobwezeretsera zonse sizofunikira - izikhala ndi deta yomweyi, ndipo unyolo wowonjezera udzagawidwa mu "subchain". Njirayi imatchedwa kupititsa patsogolo, ndipo ndi njira iyi yomwe imadzutsa gawo lalikulu la mafunso kuchokera kwa makasitomala athu.
Kusungirako kumagwiritsidwa ntchito pano pochotsa gawo lakale kwambiri la unyolo (kuchokera pa zosunga zobwezeretsera zonse mpaka pakuwonjezera). Nthawi yomweyo, sitidzachotsa zosunga zobwezeretsera zonse kapena gawo limodzi lazowonjezera. "Subchain" yonse imachotsedwa kwathunthu nthawi imodzi. Tanthauzo la kuika chiwerengero cha mfundo zikusinthanso - ngati mwa njira zina izi ndizo chiwerengero chovomerezeka chovomerezeka, pambuyo pake kusungidwa kuyenera kugwiritsidwa ntchito, ndiye apa kuyika uku kumatsimikizira chiwerengero chochepa. Mwa kuyankhula kwina, mutachotsa "subchain" yakale kwambiri, chiwerengero cha mfundo mu gawo lotsalira sayenera kugwera pansi pa izi.
Ndiyesera kufotokoza lingaliro ili mwatsatanetsatane. Tiyerekeze kuti kusungirako kwakhazikitsidwa ku mfundo za 3, ntchitoyo imayenda tsiku lililonse ndikusunga kwathunthu Lolemba. Kusunga pankhaniyi kudzagwiritsidwa ntchito pamene chiwerengero chonse cha mfundo chikafika pa 10:
Nchifukwa chiyani pali 10 kale pamene amaika 3? Zosunga zobwezeretsera zonse zidapangidwa Lolemba. Kuyambira Lachiwiri mpaka Lamlungu ntchitoyo idapanga zowonjezera. Pomaliza, Lolemba lotsatira zosunga zobwezeretsera zonse zimapangidwanso ndipo pokhapokha ma increments a 2 atapangidwa amatha kuchotsedwa gawo lonse la unyolo, chifukwa mfundo zotsalira sizingagwere pansi pa seti 3.
Ngati lingaliro liri lomveka, ndiye ndikupangira kuti muyese kuwerengera nokha. Tiyeni titenge zotsatirazi: ntchitoyo imayambitsidwa kwa nthawi yoyamba Lachinayi (mwachibadwa, zosunga zobwezeretsera zidzapangidwa). Ntchitoyi yakhazikitsidwa kuti ipange zosunga zobwezeretsera Lachitatu ndi Lamlungu ndikusunga malo 8 ochira. Kodi kusungitsa kudzagwiritsidwa ntchito liti koyamba?
Kuti muyankhe funsoli, ndikupangira kuti mutenge kapepala, kanizani pa tsiku la sabata ndikulemba mfundo yomwe imapangidwa tsiku lililonse. Yankho lidzakhala lodziwikiratu
Yankhani
Kufotokozera: kuti muyankhe, ingodzifunsani nokha "kosungirako kudzagwiritsidwa ntchito liti"? Yankho ndi pamene tingathe kuchotsa mfundo 3 oyambirira (VBK, VIB, VIB) ndi ena onse unyolo si kugwera pansi chofunika 8 mfundo. Zimakhala zoonekeratu kuti tidzatha kuchita zimenezi tikakhala ndi mfundo 11 zonse, ndiye kuti Lamlungu la sabata yachiwiri.
Owerenga ena angatsutse kuti: "Chifukwa chiyani zonsezi ngati zilipo ?. Palibe kukayikira kuti ichi ndi chida chothandiza kwambiri, ndipo nthawi zina ndikanachigwiritsa ntchito, koma chimakhalanso ndi malire. Choyamba, sikukulolani kuti mutchule zikhalidwe zoyamba, ndipo nthawi zambiri funso ndiloti "tili ndi unyolo wotere, chingachitike bwanji ngati tisintha makonda awa?" Chachiwiri, chidacho sichikumveka bwino. Kuwonetsa tsamba la RPS kwa makasitomala, sindinapeze kumvetsetsa kulikonse, koma nditajambula monga chitsanzo (ngakhale kugwiritsa ntchito utoto womwewo), tsiku ndi tsiku, zonse zinamveka bwino.
Pomaliza, sitinaganizire njira ya "Sinthani maunyolo am'mbuyomu kukhala obweza" (yomwe ili ndi nambala 5). Izi nthawi zina zimasokoneza makasitomala omwe amaziyambitsa "zokha", kufuna kungoyambitsa zosunga zobwezeretsera. Pakadali pano, njirayi imatsegula njira yapadera yosungira. Popanda kulowa mwatsatanetsatane, ndinena nthawi yomweyo kuti panthawiyi yachitukuko, "Sinthani maunyolo osunga zobwezeretsera m'mbuyomu" ndi njira yachikale, ndipo sindingathe kuganiza za chochitika chimodzi chomwe chiyenera kugwiritsidwa ntchito. Mtengo wake ndi wokayikitsa kotero kuti kwa nthawi ndithu Anton Gostev mwiniwakeyo adayitana kudzera pabwaloli, kupempha kuti amutumizire zitsanzo za ntchito zake zothandiza (ngati muli nazo, lembani mu ndemanga, ndikukondwera kwambiri). Ngati palibe (ndikuganiza kuti izi zidzakhala choncho), ndiye kuti njirayo idzachotsedwa m'matembenuzidwe amtsogolo.
Ntchitoyo ipanga ma increments (VIB) mpaka tsiku lomwe zosunga zobwezeretsera zonse zakonzedwa. Patsiku lino, VBK imapangidwadi, koma mfundo zonse VBK iyi isanachitike imasinthidwa kukhala ma rollbacks (VRB). Pambuyo pake, ntchitoyi ipitiliza kupanga zowonjezera pazosunga zonse mpaka zosunga zobwezeretsera zina. Zotsatira zake, kusakaniza kophulika kwa mafayilo a VBK, VBR ndi VIB kumapangidwa mu unyolo. Kusunga kumagwiritsidwa ntchito mosavuta - pochotsa VBR yomaliza:
Mavuto
Kupatula kumvetsetsa momwe zimagwirira ntchito, zovuta zambiri zomwe zimachitika mukamagwiritsa ntchito njira yowonjezera nthawi zambiri zimagwirizanitsidwa ndi zosunga zobwezeretsera zonse. Zosunga zobwezeretsera nthawi zonse ndizofunikira pamachitidwe awa, apo ayi chosungiracho chidzaunjikira mfundo mpaka zitadzaza.
Mwachitsanzo, zosunga zobwezeretsera zonse zitha kupangidwa kawirikawiri. Tiyerekeze kuti ntchitoyo yakhazikitsidwa kuti isunge mfundo 10, ndipo zosunga zobwezeretsera zonse zimapangidwa kamodzi pamwezi. Zikuwonekeratu kuti chiwerengero chenicheni cha mfundo pano chidzakhala chachikulu kwambiri kuposa chomwe chikuwonetsedwa. Kapena ntchitoyo nthawi zambiri imayikidwa kuti igwire ntchito mopanda malire ndikusunga mfundo 50. Kenako wina mwangozi adapanga zosunga zobwezeretsera zonse. Ndizo zonse, kuyambira pano ntchitoyo idzadikirira mpaka mfundo yonse itapeza ma increments 49, pambuyo pake idzagwiritsa ntchito kusungirako ndikubwerera kuzinthu zonse.
Nthawi zina, zosunga zobwezeretsera zonse zimakhazikitsidwa kuti zizipangidwa pafupipafupi, koma pazifukwa zina sizitero. Ndilemba chifukwa chodziwika kwambiri pano. Makasitomala ena amakonda kugwiritsa ntchito njira ya "run after" ndikukonza ntchito kuti ziyende bwino. Tiyeni titenge chitsanzo ichi: pali ntchito zitatu zomwe zimagwira tsiku lililonse ndikupanga zosunga zobwezeretsera Lamlungu. Ntchito yoyamba imayamba pa 3, ena onse amayambitsidwa mu unyolo. Kusunga zosunga zobwezeretsera kumatenga mphindi 22.30, motero pofika 10 ntchito zonse zimatha kugwira ntchito. Koma kusunga kwathunthu kumatenga ola limodzi, kotero Lamlungu zotsatirazi zimachitika: ntchito yoyamba imachokera ku 23.00 mpaka 22.30. Kenako kuyambira 23.30 mpaka 23.30. Koma ntchito yachitatu iyamba Lolemba. Zosunga zobwezeretsera zonse zakhazikitsidwa Lamlungu, chifukwa chake sizingachitike. Ntchitoyi imadikirira kusungitsa kwathunthu kuti mugwiritse ntchito posungira. Chifukwa chake samalani mukamagwiritsa ntchito njira ya "run after" kapena musagwiritse ntchito konse - ingokhazikitsani ntchito kuti ziyambike nthawi imodzi ndikulola wokonza zinthu kuti agwire ntchito yake.
Njira yovuta "Chotsani zinthu zochotsedwa"
Mutadutsa makonda a ntchitoyo Kusunga - MwaukadauloZida - Kukonza, mutha kukumana ndi njira "chotsani zinthu zomwe zachotsedwa pambuyo", zomwe zitha kuwerengedwa m'masiku.
Makasitomala ena amayembekezera kuti izi zidzasungidwa. M'malo mwake, iyi ndi njira yosiyana kotheratu, kusamvetsetsa komwe kungayambitse zotsatira zosayembekezereka. Komabe, choyamba, tiyenera kufotokoza momwe B&R imachitira pakachitika pomwe makina ochepa okha ndi omwe amathandizidwa bwino pagawo.
Tiyeni tiyerekeze izi: ntchito yowonjezereka yokonzedwa kuti isunge mfundo 6. Pali makina a 2 pantchitoyo, imodzi imasungidwa bwino nthawi zonse, ina nthawi zina imapereka zolakwika. Chifukwa chake, pofika pa mfundo yachisanu ndi chiwiri zinthu zotsatirazi zidabuka:
Nthawi yofunsira kusungirako, koma galimoto imodzi ili ndi mfundo 7, ndipo inayo 4. Kodi kusungirako kudzagwiritsidwa ntchito pano? Yankho ndi lakuti inde, zidzatero. Ngati chinthu chimodzi chathandizidwa, B&R imawona kuti mfundoyo idapangidwa.
Mkhalidwe wofananawo ungabwere ngati makina ena sanaphatikizidwe mu ntchitoyo panthawi inayake. Izi zimachitika, mwachitsanzo, pamene makina akuwonjezeredwa ku ntchito osati payekha, koma monga gawo la zotengera (zikwatu, zosungirako) ndipo makina ena amasamukira ku chidebe china kwakanthawi. Pankhaniyi, ntchitoyi idzaonedwa kuti ndi yopambana, koma mu ziwerengero mudzapeza uthenga wopempha kuti mumvetsere kuti makina oterowo sakukonzedwanso ndi ntchitoyi.
Kodi chingachitike ndi chiyani ngati simusamala izi? Pankhani ya njira zopanda malire-zowonjezereka kapena zowonjezereka, chiwerengero cha malo obwezeretsanso makina a "vuto" chidzachepa ndi gawo lililonse mpaka kufika ku 1, kusungidwa mu VBK. Mwa kuyankhula kwina, ngakhale makinawo atasungidwa kwa nthawi yaitali, malo amodzi obwezeretsa adzakhalabe. Mkhalidwewu ndi wosiyana ngati zosunga zobwezeretsera nthawi ndi nthawi zimayatsidwa. Ngati munyalanyaza zizindikiro kuchokera ku B&R, mfundo yomaliza imatha kuchotsedwa limodzi ndi gawo lakale la unyolo.
Pomvetsa mfundo izi, mukhoza potsiriza kuganizira "Chotsani zichotsedwa zinthu deta pambuyo" njira. Idzachotsa mfundo zonse zamakina enaake ngati makinawo sanasungidwe kumbuyo kwa masiku X. Chonde dziwani kuti zosinthazi sizikuyankha zolakwika (ndinayesa, koma sizinagwire ntchito). Sipayenera kukhala ngakhale kuyesa kusunga makinawo. Zikuwoneka kuti njirayi ndi yothandiza ndipo iyenera kusungidwa nthawi zonse. Ngati woyang'anira adachotsa makinawo pa ntchitoyo, ndiye kuti patapita nthawi ndizomveka kuchotsa mndandanda wazinthu zosafunikira. Komabe, makonda amafunikira chisamaliro ndi chisamaliro.
Ndiroleni ndikupatseni chitsanzo kuchokera muzochita: zida zingapo zidawonjezeredwa ku ntchitoyi, zomwe zidali zamphamvu kwambiri. Chifukwa chosowa RAM, seva ya B&R inali kukumana ndi mavuto omwe sanadziwike. Ntchitoyi idayamba ndikuyesera kupanga zosunga zobwezeretsera zamakina, kupatula imodzi, yomwe panthawiyo inalibe mu chidebecho. Popeza makina ambiri adapanga zolakwika, mwachisawawa B&R iyenera kuyesa 3 zowonjezera zosungira makina a "vuto". Chifukwa cha zovuta zonse ndi RAM, kuyesaku kunatenga masiku angapo. Panalibe kuyesa mobwerezabwereza kupanga zosunga zobwezeretsera za VM yosowa (kusowa kwa VM sikulakwa). Chotsatira chake, pakuyesera mobwerezabwereza, chikhalidwe cha "Chotsani zinthu zochotsedwa" chinakwaniritsidwa ndipo mfundo zonse pamakina zinachotsedwa.
Ponena za izi, nditha kunena izi: ngati muli ndi zidziwitso zomwe zakhazikitsidwa pazotsatira zantchito, komanso bwino, gwiritsani ntchito kuphatikiza ndi Veeam ONE, ndiye kuti izi sizingachitike kwa inu. Ngati muyang'ana seva ya B&R kamodzi pa sabata kuti muwone ngati zonse zikuyenda, ndiye kuti ndibwino kukana zosankha zomwe zingayambitse kuchotsedwa kwa zosunga zobwezeretsera.
Zomwe zawonjezedwa mu v.10
Zomwe tidakambirana kale zidalipo mu B&R m'mitundu yambiri. Popeza tamvetsetsa mfundo zoyendetsera ntchitoyi, tiyeni tiwone zomwe zawonjezeredwa ku "khumi".
Kusunga tsiku ndi tsiku
Pamwambapa tidayang'ana ndondomeko yosungirako "classical" potengera chiwerengero cha mfundo. Njira ina ndiyo kukhazikitsa "masiku" m'malo mwa "kubwezeretsanso mfundo" mumndandanda womwewo.
Lingaliro likuwonekera kuchokera ku dzina - kusungirako kudzasunga masiku angapo, koma chiwerengero cha mfundo tsiku lililonse zilibe kanthu. Pankhaniyi, muyenera kukumbukira zotsatirazi:
- Tsiku lapano silimaganiziridwa powerengera kusungirako
- Masiku omwe ntchitoyi sinagwire ntchito amawerengedwanso. Izi ziyenera kukumbukiridwa kuti musataye mwangozi mfundo za ntchito zomwe zimagwira ntchito mosakhazikika.
- Malo obwezeretsa amawerengedwa kuyambira tsiku lomwe kulengedwa kwake kunayamba (ie ngati ntchitoyo idayamba kugwira ntchito Lolemba ndikutha Lachiwiri, ndiye kuti iyi ndi mfundo kuyambira Lolemba)
Apo ayi, mfundo zogwiritsira ntchito kusunga ndi ntchito zimatsimikiziridwa ndi njira yosungira yosankhidwa. Tiyeni tiyese ntchito ina yowerengera pogwiritsa ntchito njira yowonjezereka yomweyi. Tinene kuti kusungirako kwakhazikitsidwa kwa masiku 8, ntchitoyo imayenda maola 6 aliwonse ndikusunga kwathunthu Lachitatu. Komabe, ntchitoyi sikugwira ntchito Lamlungu. Ntchitoyi ikuchitika Lolemba koyamba. Kodi kusunga kudzagwiritsidwa ntchito liti?
Yankhani
Monga nthawi zonse, ndi bwino kujambula chizindikiro. Ndidzilola kuti ndichepetse ntchitoyo ndipo sindidzajambula mfundo zonse zomwe zimapangidwira tsiku lililonse, chifukwa kuchuluka kwa mfundo patsiku zilibe kanthu apa. Ndizofunikira kwa ife kuti Lolemba loyamba ndi Lachitatu mfundo yoyamba idzakhala yosunga zobwezeretsera zonse, koma masiku otsalawo ntchitoyi idzangopanga 4 mfundo zowonjezera.
Tikuwonetsetsa kuti kusungirako kudzagwiritsidwa ntchito pochotsa zosunga zobwezeretsera Lolemba komanso kuchuluka kwake. Kodi zimenezi zidzachitika liti? Pamene ena onse unyolo ali 8 masiku. Panthawi imodzimodziyo, sitimawerengera tsiku lamakono, koma mosiyana, timawerengera Lamlungu. Choncho, yankho ndi Lachinayi la sabata yachiwiri.
GFS yosungiramo ntchito zanthawi zonse
Isanafike v.10, njira yosungira ya Agogo-Atate-Mwana (GFS) inalipo kokha pa ntchito zosunga zosunga zobwezeretsera ndi ntchito zamakope a tepi. Tsopano ikupezeka kuti isungidwe nthawi zonse.
Ngakhale kuti izi sizikugwirizana ndi mutu wamakono, sindingathe kunena kuti ntchito yatsopanoyi sikutanthauza kuchoka ku njira ya 3-2-1. Kukhalapo kwa malo osungiramo zakale m'malo akuluakulu sikukhudza kudalirika kwake mwanjira iliyonse. Zimamveka kuti GFS idzagwiritsidwa ntchito limodzi ndi Scale-out repository kuti ikweze mfundozi ku S3 ndi zosungirako zofanana. Ngati simugwiritsa ntchito, ndiye kuti ndi bwino kupitiliza kusunga mfundo zoyambira ndi zosungira m'malo osiyanasiyana.
Tsopano tiyeni tiwone mfundo zopangira mfundo za GFS. M'makonzedwe a ntchito, pa sitepe Yosungirako, batani lapadera lawonekera lomwe limayitana mndandanda wotsatirawu:
Zofunikira za GFS zitha kuwiritsidwa ku mfundo zingapo (zindikirani kuti GFS imagwira ntchito mosiyana ndi mitundu ina ya ntchito, koma zambiri pambuyo pake):
- Ntchitoyi sipanga zosunga zobwezeretsera zonse za GFS point. M'malo mwake, zosunga zobwezeretsera zoyenera kwambiri zomwe zilipo zidzagwiritsidwa ntchito. Chifukwa chake, ntchitoyi iyenera kugwira ntchito mowonjezereka ndi zosunga zobwezeretsera nthawi ndi nthawi, kapena zosunga zobwezeretsera zonse ziyenera kupangidwa pamanja ndi wogwiritsa ntchito.
- Ngati nthawi imodzi yokha yathandizidwa (mwachitsanzo, sabata), ndiye kumayambiriro kwa nthawi ya GFS ntchitoyo idzangoyamba kuyembekezera zosunga zobwezeretsera zonse ndikuyika yoyamba yoyenera kukhala GFS.
Chitsanzo: ntchitoyo idakonzedwa kuti isunge GFS sabata iliyonse pogwiritsa ntchito zosunga zobwezeretsera Lachitatu. Ntchitoyi imachitika tsiku lililonse, koma zosunga zobwezeretsera zonse zakonzedwa Lachisanu. Pankhaniyi, nthawi ya GFS idzayamba Lachitatu ndipo ntchitoyi idzayamba kuyembekezera mfundo yoyenera. Idzawonekera Lachisanu ndipo ikhala ndi mbendera ya GFS.
- Ngati nthawi zingapo zikuphatikizidwa nthawi imodzi (mwachitsanzo, mlungu uliwonse ndi mwezi uliwonse), ndiye B & R idzagwiritsa ntchito njira yomwe imalola kuti mfundo yomweyi igwiritsidwe ntchito ngati GFS ya nthawi zingapo (kusunga malo). Mbendera zidzaperekedwa mwadongosolo, kuyambira ndi wamng'ono kwambiri.
Chitsanzo: GFS ya mlungu ndi mlungu imakhazikitsidwa Lachitatu, ndipo GFS ya pamwezi imayikidwa sabata yomaliza ya mweziwo. Ntchitoyi imayenda tsiku lililonse ndikupanga zosunga zobwezeretsera Lolemba ndi Lachisanu.
Kuti mukhale osavuta, tiyeni tiyambe kuwerengera kuyambira sabata lomaliza la mweziwo. Sabata ino zosunga zobwezeretsera zonse zidzapangidwa Lolemba, koma sizidzanyalanyazidwa chifukwa nthawi ya sabata ya GFS imayamba Lachitatu. Koma zosunga zobwezeretsera Lachisanu ndizoyenera kwathunthu pamfundo ya GFS. Dongosololi ndi lodziwika kale kwa ife.
Tsopano tiyeni tione zimene zimachitika mlungu wotsiriza wa mwezi. Nthawi ya GFS pamwezi idzayamba Lolemba, koma Lolemba la VBK silidzadziwika kuti GFS chifukwa ntchitoyo ikufuna kuyika chizindikiro cha VBK imodzi ngati mfundo ya GFS pamwezi ndi sabata. Pankhaniyi, kufufuza kumayamba ndi sabata iliyonse, chifukwa ndi tanthawuzo likhoza kukhala la mwezi uliwonse.
Komabe, ngati muphatikiza magawo a sabata ndi pachaka okha, azichita mosadalira wina ndi mnzake ndipo amatha kuyika ma VBK awiri osiyana ngati ma GFS.
Zosunga zosunga zobwezeretsera ntchito
Mtundu wina wa ntchito yomwe nthawi zambiri imafuna kumveketsa bwino za ntchitoyo. Choyamba, tiyeni tiwone njira ya "classic" yogwirira ntchito, popanda zatsopano v.10
Njira yosavuta yosungira
Mwachikhazikitso, ntchito zotere zimagwira ntchito mopanda malire. Kupanga mfundo kumatsimikiziridwa ndi magawo awiri - nthawi yokopera ndi kuchuluka komwe mukufuna kuchira (palibe kusungitsa masana pano). Nthawi yokopera imayikidwa pa tsamba loyamba la Job popanga ntchito:
Chiwerengero cha mfundo chimatsimikiziridwa patsogolo pang'ono pa Target tabu
Ntchitoyi imapanga mfundo imodzi pa nthawi iliyonse (ndi mfundo zingati zomwe zinapangidwira VM ndi ntchito zoyambirira zilibe kanthu). Pamapeto pa nthawiyi, mfundo yatsopanoyo imatsirizidwa ndipo, ngati kuli kofunikira, kusungirako kumagwiritsidwa ntchito pophatikiza VBK ndi kuwonjezereka kwakale kwambiri. Njirayi ndi yodziwika kale kwa ife.
Njira yosungira pogwiritsa ntchito GFS
BCJ imathanso kusunga zolemba zakale. Izi zimakonzedwa pa tabu ya Target yomweyi, pansi pa makonzedwe a chiwerengero cha malo obwezeretsa:
Mfundo za GFS zitha kupangidwa m'njira ziwiri - mwakupanga, kugwiritsa ntchito deta pankhokwe yachiwiri, kapena kutengera zosunga zobwezeretsera zonse ndikuwerenga zonse kuchokera kunkhokwe yayikulu (yoyendetsedwa ndi njira yolembedwa 3). Kusunga muzochitika zonsezi kudzakhala kosiyana kwambiri, kotero tidzakambirana mosiyana.
GFS yopangidwa
Pankhaniyi, mfundo ya GFS sinapangidwe ndendende pa tsiku losankhidwa. M'malo mwake, mfundo ya GFS idzapangidwa pamene VIB ya tsikulo yomwe mfundo ya GFS inakonzedwa kuti ipangidwe idzaphatikizidwa ndi zosunga zobwezeretsera zonse. Izi nthawi zina zimayambitsa kusamvana, chifukwa nthawi imadutsa ndipo palibe mfundo ya GFS. Ndipo shaman wamphamvu yekha wochokera ku chithandizo chaumisiri anganeneretu tsiku lomwe mfundoyo idzawonekere. M'malo mwake, matsenga safunikira - ingoyang'anani kuchuluka kwa mfundo ndi nthawi yolumikizana (ndi mfundo zingati zomwe zimapangidwa tsiku lililonse). Yesani kuwerengera nokha pogwiritsa ntchito chitsanzo ichi: ntchitoyo yakhazikitsidwa kuti isunge mfundo 7, nthawi yolumikizana ndi maola 12 (i.e. 2 mfundo patsiku). Pakalipano, pali kale mfundo za 7 mu unyolo, lero ndi Lolemba, ndipo kupangidwa kwa mfundo ya GFS kukukonzekera tsiku lino. Kodi chidzalengedwa tsiku lanji?
Yankhani
Apa ndi bwino kufotokoza momwe unyolo udzasinthira pakapita nthawi, tsiku ndi tsiku:
Chifukwa chake Lolemba, kuwonjezereka komaliza mu unyolo kumalembedwa ngati GFS, koma palibe kusintha kwina komwe kumachitika. Tsiku lililonse ntchitoyo imapanga mfundo ziwiri zatsopano, ndipo kusungirako kumapititsa patsogolo unyolo. Pomaliza, Lachinayi ifika nthawi yoti mugwiritse ntchito kusungitsa pakukula komweko. Gawoli lidzatenga nthawi yayitali kuposa nthawi zonse - chifukwa ntchitoyi "idzachotsa" midadada yofunikira pa unyolo ndikupanga mfundo yatsopano. Kuyambira nthawi ino, padzakhala kale mfundo 2 mu unyolo - 8 mu unyolo waukulu + GFS.
Kupanga mfundo za GFS ndi "Werengani mfundo yonse".
Pamwambapa ndinanena kuti BCJ imagwira ntchito mopanda malire. Tsopano tiwona chosiyana ndi lamulo ili. Njira ya "Werengani mfundo yonse" ikayatsidwa, mfundo ya GFS idzapangidwa ndendende tsiku lomwe linakonzedwa. Ntchito yokhayo idzagwira ntchito mowonjezereka ndi zosunga zobwezeretsera nthawi ndi nthawi, zomwe takambirana pamwambapa. Kusungirako kudzagwiritsidwanso ntchito pochotsa gawo lakale kwambiri la unyolo. Komabe, pamenepa, zowonjezera zokha zidzachotsedwa, ndipo zosunga zobwezeretsera zonse zidzasiyidwa ngati mfundo ya GFS. Chifukwa chake, mfundo zolembedwa ndi mbendera za GFS sizimaganiziridwa powerengera kusungidwa.
Tinene kuti ntchitoyo yakhazikitsidwa kuti isunge ma point 7 ndikupanga mfundo ya GFS sabata Lolemba. Pankhaniyi, Lolemba lililonse ntchitoyo imapanga zosunga zobwezeretsera zonse ndikuzilemba ngati GFS. Kusungirako kudzagwiritsidwa ntchito pamene, mutatha kuchotsa zowonjezera kuchokera ku gawo lakale kwambiri, chiwerengero cha zowonjezera zotsalira sizitsika pansi pa 7. Izi ndi momwe zimawonekera pajambula:
Kotero, pakutha kwa sabata yachiwiri pali mfundo 14 zonse mu unyolo. Pa sabata yachiwiri, ntchitoyi idapanga ma point 7. Ngati iyi inali ntchito yosavuta, kusungirako kukadagwiritsidwa ntchito kale. Koma iyi ndi BCJ yokhala ndi kusungidwa kwa GFS, kotero sitiwerengera mfundo za GFS, zomwe zikutanthauza kuti pali 6 okha. Mu sabata yachitatu timapanga zosunga zobwezeretsera zonse ndi mbendera ya GFS. 15 mfundo, koma kachiwiri sitiwerengera iyi. Ndipo potsiriza, Lachiwiri la sabata lachitatu, timapanga zowonjezera. Tsopano, ngati tichotsa kuchuluka kwa unyolo kwa sabata yoyamba, kuchuluka kwa ma increments kudzakwaniritsa kusungidwa kokhazikitsidwa.
Monga tafotokozera pamwambapa, munjira iyi ndikofunikira kwambiri kuti ma backups athunthu amapangidwa nthawi zonse. Tiyerekeze, ngati muyika kusungirako kwakukulu kwa masiku 7, koma mfundo imodzi yokha yapachaka, n'zosavuta kuganiza kuti zowonjezera zidzaunjikana kwambiri, kuposa 1. Zikatero, ndi bwino kugwiritsa ntchito njira yopangira kupanga. GFS.
Komanso "Chotsani zinthu zochotsedwa"
Njira iyi iliponso ku BCJ:
Lingaliro la njirayi pano ndilofanana ndi ntchito zosunga zobwezeretsera nthawi zonse - ngati makina sanasinthidwe kwa masiku omwe atchulidwa, ndiye kuti deta yake imachotsedwa pa unyolo. Komabe, kwa BCJ phindu la njirayi ndilokwera kwambiri, ndipo ndichifukwa chake.
Mumayendedwe abwinobwino, BCJ imagwira ntchito mopitilira muyeso, kotero ngati nthawi ina makina achotsedwa ntchito, kusungirako kumachotsa pang'onopang'ono mfundo zonse zobwezeretsa mpaka patsala imodzi yokha - mu VBK. Tsopano tiyeni tiyerekeze kuti ntchitoyi idakonzedwabe kuti ipange mfundo za GFS zopangira. Nthawi ikadzafika, ntchitoyo iyenera kupanga GFS yamakina onse omwe ali mu unyolo. Ngati makina ena alibe mfundo zatsopano, ndiye kuti muyenera kugwiritsa ntchito yomwe ili. Ndipo kotero nthawi zonse. Zotsatira zake, zinthu zotsatirazi zingachitike:
Samalani ndi gawo la Mafayilo: tili ndi VBK yayikulu ndi mfundo ziwiri za GFS sabata iliyonse. Ndipo tsopano ku Bwezerani mfundo gawo - kwenikweni, mafayilowa ali ndi chithunzi chomwecho cha makina. Mwachibadwa, palibe mfundo mu mfundo zotere za GFS, zimangotenga malo.
Izi ndizotheka pokhapokha mukugwiritsa ntchito GFS yopanga. Pofuna kupewa izi, gwiritsani ntchito njira ya "Chotsani zichotsedwa". Ingokumbukirani kuyiyika kwa masiku okwanira. Thandizo laukadaulo lawona milandu yomwe mwayiwu udakhazikitsidwa kwa masiku ocheperako kuposa nthawi yolumikizira - BCJ idayamba kusokoneza ndikuchotsa mfundo zisanapangidwe.
Chonde dziwani kuti izi sizikhudza mfundo za GFS zomwe zidapangidwa kale. Ngati mukufuna kuyeretsa zakale, muyenera kuchita izi pamanja - ndikudina kumanja pamakina ndikusankha "Chotsani ku disk" (pazenera lomwe likuwoneka, musaiwale kuyang'ana bokosi "Chotsani GFS zonse zosunga zobwezeretsera") :
Innovation v.10 - kukopera mwamsanga
Popeza tathana ndi magwiridwe antchito a "classic", tiyeni tipite ku chatsopanocho. Pali luso limodzi, koma lofunika kwambiri. Iyi ndi njira yatsopano yogwirira ntchito.
Palibe chinthu ngati "nthawi yolumikizirana"; ntchitoyo imayang'anira nthawi zonse ngati mfundo zatsopano zawonekera ndikuzikopera zonse, ngakhale zitakhala zingati. Koma panthawi imodzimodziyo, ntchitoyo imakhalabe yowonjezera, ndiko kuti, ngakhale ntchito yaikulu imapanga VBK kapena VRB, mfundozi zidzakopedwa ngati VIB. Kupanda kutero, palibe zodabwitsa munjira iyi - zonse zokhazikika ndi GFS zosungira zimagwira ntchito molingana ndi malamulo omwe tafotokozazi (komabe, GFS yokhayo yopangidwa ikupezeka pano).
Ma disks akuzungulira. Makhalidwe a repositories okhala ndi ma drive ozungulira
Kuwopseza kosalekeza kwa ma virus a ransomware kwapangitsa kuti ikhale mulingo wachitetezo cha de facto kukhala ndi kopi ya data pa sing'anga pomwe kachilomboka sikangathe kufikira. Njira imodzi ndiyo kugwiritsa ntchito ma disk rotation repositories, kumene ma disks amagwiritsidwa ntchito imodzi panthawi imodzi: pamene disk imodzi imagwirizanitsidwa ndi kulembedwa, zina zonse zimasungidwa pamalo otetezeka.
Kuti muphunzitse B&R kuti igwire ntchito ndi nkhokwe zotere, muyenera dinani batani la Advanced muzosunga zosungira, pagawo la Repository, ndikusankha njira yoyenera:
Pambuyo pa izi, VBR idzayembekezera kuti tcheni chomwe chilipo chidzazimiririka nthawi ndi nthawi kuchokera kumalo osungira, zomwe zikutanthauza kuzungulira kwa disk. Kutengera mtundu wa malo ndi mtundu wa ntchito, B&R imachita mosiyana. Izi zitha kuyimiridwa ndi tebulo ili:
Tiyeni tione njira iliyonse.
Ntchito wamba ndi malo osungira Windows
Chifukwa chake, tili ndi ntchito yomwe imasunga unyolo ku disk yoyamba. Panthawi yozungulira, unyolo wopangidwa umasowa, ndipo ntchitoyo iyenera kupulumuka kutayika uku. Amapeza chitonthozo popanga zosunga zobwezeretsera zonse. Chifukwa chake, kuzungulira kulikonse kumatanthauza kusunga kwathunthu. Koma chimachitika ndi chiyani pazigawo zomwe zili pa disk yolumikizidwa? Amakumbukiridwa ndikuganiziridwa powerengera kusungidwa. Choncho, chiwerengero cha mfundo mu ntchito ndi mfundo zingati zomwe ziyenera kusungidwa pa disks zonse. Nachi chitsanzo:
Ntchitoyi imagwira ntchito mopanda malire ndipo imakonzedwa kuti isunge mfundo zitatu zobwezeretsa. Koma timakhalanso ndi diski yachiwiri, ndipo timayitembenuza kamodzi pa sabata (pakhoza kukhala ma disks ambiri, izi sizikusintha kwenikweni).
Mu sabata yoyamba, ntchitoyi idzapanga mfundo pa disk yoyamba ndikuphatikiza zina zowonjezera. Choncho, chiwerengero chonse cha mfundo chidzakhala chofanana ndi atatu:
Kenaka timagwirizanitsa galimoto yachiwiri. Pambuyo poyambitsa, B&R idzawona kuti disk yasinthidwa. Unyolo pa disk yoyamba udzazimiririka kuchokera pa mawonekedwe, koma zambiri za izo zidzakhalabe mu database. Tsopano ntchitoyi idzasunga mfundo za 3 pa disk yachiwiri. Zinthu zonse zikhala motere:
Pomaliza, timagwirizanitsa galimoto yoyamba. Musanapange mfundo yatsopano, ntchitoyi idzayang'ana zomwe zikuchitika ndi kusungidwa. Ndipo kusungirako, ndikukumbutsani, kwakhazikitsidwa kuti musunge mapointi atatu. Pakalipano, tili ndi mfundo za 3 pa disk 3 (koma imachotsedwa ndikusungidwa pamalo otetezeka omwe B & R sangathe kufika) ndi mfundo za 2 pa disk 3 (koma iyi ikugwirizana). Izi zikutanthauza kuti titha kuchotsa mfundo za 1 mosamala kuchokera pa disk 3, chifukwa zimadutsa kusungirako. Pambuyo pake ntchitoyi imapanga zosunga zobwezeretsera zonse, ndipo unyolo wathu umayamba kuwoneka motere:
Ngati kusungirako kukonzedwa kuti kusungidwe masiku m'malo mwa kuchuluka kwa mfundo, ndiye kuti malingalirowo sasintha. Kuphatikiza apo, kusungidwa kwa GFS sikuthandizidwa konse mukamagwiritsa ntchito zosungirako zokhala ndi disk rotation.
Ntchito yokhazikika komanso malo osungira a Linux
Izi ndizothekanso, koma nthawi zambiri sizikulimbikitsidwa chifukwa cha zoletsa zomwe zimayikidwa. Ntchitoyo idzachitapo kanthu pa kusinthasintha kwa disk ndi kuzimiririka kwa unyolo mofananamo - popanga zosunga zobwezeretsera zonse. Cholepheretsacho ndi chifukwa cha njira yochepetsera yosungira.
Apa, panthawi yozungulira, unyolo wonse pa disk yolumikizidwa umangochotsedwa ku database ya B&R. Chonde dziwani kuti kuchokera ku database, mafayilowo amakhalabe pa disk. Zitha kutumizidwa kunja ndikugwiritsidwa ntchito kuti zibwezeretsedwe, koma ndizosavuta kuganiza kuti posachedwa maunyolo oyiwalika oterowo adzadzaza nkhokwe yonse.
Yankho ndikuwonjezera DWORD ForceDeleteBackupFiles monga zasonyezedwera patsamba lino: . Ntchitoyo idzayamba kungochotsa zonse zomwe zili mufoda yantchito kapena chikwatu chosungira (kutengera mtengo) pakusintha kulikonse.
Komabe, uku sikusungidwa kokongola, koma kuyeretsa zonse zomwe zili mkati. Tsoka ilo, chithandizo chaukadaulo chinakumana ndi milandu pomwe chosungira chinali chabe chikwatu cha diski, pomwe, kuwonjezera pa zosunga zobwezeretsera, deta ina idapezeka. Zonsezi zinawonongeka panthawi ya kasinthasintha.
Kuphatikiza apo, ForceDeleteBackupFiles ikayatsidwa, imagwira ntchito kumitundu yonse ya nkhokwe, ndiye kuti, ngakhale zosungira pa Windows zimasiya kugwiritsa ntchito zosungira ndikuyamba kufufuta zomwe zili. Mwanjira ina, disk yakomweko pa Windows ndiye chisankho chabwino kwambiri chosungirako chosungirako.
Koperani zosunga zobwezeretsera ndi Windows repository
Zinthu zimakhala zosangalatsa kwambiri ndi BCJ. Sikuti imangokhala ndi kusungidwa kwathunthu, koma palibe chifukwa chosunga zosunga zobwezeretsera nthawi zonse mukasintha disk! Zimagwira ntchito motere:
Choyamba, B&R imayamba kupanga mfundo pa chimbale choyamba. Tiyerekeze kuti takhazikitsa kusungirako ku 3 points. Ntchitoyi idzagwira ntchito mopitilira muyeso ndikuphatikiza zonse zosafunikira (ndikukumbutsani kuti kusungidwa kwa GFS sikumathandizidwa pakadali pano).
Kenaka timagwirizanitsa galimoto yachiwiri. Popeza palibe unyolo pakali pano, timapanga zosunga zobwezeretsera zonse, pambuyo pake tili ndi unyolo wachiwiri wa mfundo zitatu:
Pomaliza, ndi nthawi yolumikizanso choyendetsa choyamba. Ndipo apa ndipamene matsenga amayambira, popeza ntchitoyi sidzapanga zosunga zobwezeretsera zonse, koma m'malo mwake ingopitiliza unyolo wowonjezera:
Pambuyo pake, pafupifupi diski iliyonse idzakhala ndi unyolo wake wodziimira. Choncho, kusungirako apa sikukutanthauza chiwerengero cha mfundo pa disks zonse, koma chiwerengero cha mfundo pa disk iliyonse mosiyana.
Koperani zosunga zobwezeretsera ndi Linux repositorynetwork yosungirako
Apanso, kukongola konse kumatayika ngati chosungira sichili pa Windows drive yakomweko. Script iyi imagwira ntchito mofanana ndi yomwe takambirana pamwambapa ndi ntchito yosavuta. Ndi kuzungulira kulikonse, BCJ imapanga zosunga zobwezeretsera zonse, ndipo mfundo zomwe zilipo zidzayiwalika. Kuti mupewe kutha kwa malo aulere, muyenera kugwiritsa ntchito DWORD ForceDeleteBackupFiles.
Pomaliza
Chifukwa chake, chifukwa cha lemba lalitali chotere, tawona mitundu iwiri ya ntchito. Nβzoona kuti pali ntchito zinanso zambiri, koma sizingatheke kuziganizira zonse ngati nkhani imodzi. Ngati mutatha kuwerenga mukadali ndi mafunso, lembani mu ndemanga, ndidzakhala wokondwa kuyankha ndekha.
