ICapacity Tier (okanye njengoko siyibiza ngaphakathi kweVim - captir) yavela emva ngeentsuku zeVeeam Backup kunye neReplication 9.5 Hlaziya 4 phantsi kwegama leTier yoLondolozo lweNdawo. Ingcamango emva kwayo kukwenza ukuba kwenzeke ukuhambisa ii-backups eziwileyo kwinto ebizwa ngokuba yinkqubo yokubuyisela ifestile kwindawo yokugcina into. Oku kuncede ekucoceni isithuba sedisk kwabo basebenzisi bebenayo kancinci. Kwaye olu khetho lubizwa ngokuba yiModi yokuHambisa.

Ukwenza le ntshukumo ilula (njengoko ibonakala), kwakwanele ukuhlangabezana neemeko ezimbini: zonke iingongoma ezisuka kwi-backup esusiweyo kufuneka zibe ngaphandle kwemida yefestile yokubuyisela yokusebenza ekhankanywe ngasentla, ebekwe ngokucacileyo kwi-UI. Kwaye okwesibini: ikhonkco kufuneka ibe kwinto ebizwa ngokuba "yifom etywiniweyo" (ikhonkco elitywiniweyo okanye i-Inactive Backup Chain). Oko kukuthi, akukho lutshintsho lwenzekayo kweli khonkco ekuhambeni kwexesha.

Kodwa kwi-VBR v10, ingqikelelo yongezwa ngemisebenzi emitsha- Imowudi yokuKhuphela, iMowudi etywiniweyo kunye nento enegama elinzima ukulibiza I-Immutability yavela.

Ezi zizinto ezinomdla esiza kuthetha ngazo namhlanje. Okokuqala, malunga nendlela esebenze ngayo kwi-VBR9.5u4, kwaye emva koko malunga notshintsho kwinguqulo yeshumi.

Kwaye kwanga iintshatsheli zentetho enyulu zingandixolela, kodwa kukho amagama amaninzi kakhulu angenako ukuguqulelwa.
Ke kuya kubakho itoni yee-Anglicisms apha.
Kwaye ezininzi gifs.
Kunye nemifanekiso.

• Ngaphandle kokuzisola nokuncinci. Umbhali wenqaku.

Njengoko kwakunjalo

Kulungile, masiqale ngokuhlalutya ifestile yokubuyisela esebenzayo kunye ne-backup etywiniweyo (okanye njengoko zibizwa kuxwebhu lwe-Inactive Backup Chain). Ngaphandle kokuqonda kwabo, ingcaciso eyongezelelekileyo ayinakwenzeka.

Njengoko sibona emfanekisweni, sinohlobo lwekhonkco lokugcinwa kunye neebhloko zedatha, ezifumaneka kwi-Performance tier SOBR yendawo yokugcina apho i-Capacity Tier ixhunyiwe. Ifestile yethu yokusebenza yogcino yientsuku ezintathu.

Ngokuhambelanayo, i-.vbk eyenziwe ngoMvulo itywina ikhonkco yangaphambili, ifestile yayo ibekwe kwiintsuku ezintathu. Kwaye oko kuthetha ukuba unokuqalisa ngokukhuselekileyo ukuthutha yonke into endala kunezi ntsuku zintathu ukuya kuluhlu lokudubula.

Kodwa yintoni kanye kanye eyayithethwa ngekhonkco elitywiniweyo kwaye yintoni enokuthunyelwa kuluhlu lokudubula umthamo ekuhlaziyweni 4?

Kwi-Forward Incremental, uphawu lokutywina ikhonkco kukudala i-backup entsha epheleleyo. Kwaye akunamsebenzi ukuba olu gcino lugcweleyo lufumaneka njani: zombini ii-backups ezipheleleyo ezenziweyo kunye nezisebenzayo ziyaqwalaselwa.

Kwimeko ye-Reverse, ezi zizo zonke iifayile ezingaweliyo kwifestile yokusebenza.

Kwimeko yokuya phambili ngokunyuswa ngokubuyisela umva, ezi zonke zizii-rollbacks kwaye .vbk, ukuba kukho enye .vbk kubungakanani bomsebenzi

Ngoku makhe sithathele ingqalelo ukhetho lokusebenza nge Copy Copy chain. Kuphela zizinto eziwela phantsi kweGFS eziye zathunyelwa apha. Kuba yonke into egcinwe kumatyathanga ekopi ekopi yamva nje inokutshintshwa ngendlela enye okanye enye.

Ngoku makhe sijonge phantsi kwe-hood. Apho, inkqubo ebizwa ngokuba yi-dehydration iyenzeka-ukushiya iifayile ezigciniweyo ezingenanto kubungakanani kunye nokutsala iibhloko ukusuka kwezi fayile ukuya kuluhlu lokudubula. Ukwandisa le nkqubo, okubizwa ngokuba yi-index dehydration index isetyenzisiweyo, okukuvumela ukuba ugweme ukukopisha iibhloko esele zikopishwe kuluhlu lokudubula umthamo.

Makhe sibone ukuba oku kujongeka njani ngomzekelo: Masithi sine .vbk ephume kwifestile yentengiselwano kwaye iyeyekhonkco elitywiniweyo. Oku kuthetha ukuba sinelungelo lonke lokuyihambisa kuluhlu lokufota. Ngexesha lokuhamba, ifayile yemethadatha yenziwa kwidash yomthamo kunye neebhloko zefayile edlulisiweyo. Ifayile yemetadata yenqanaba lekhonkco ichaza ukuba yintoni evimba ifayile yethu equlathwe yiyo. Kwimeko emfanekisweni, ifayile yethu yokuqala iqulathe iibhloko a, b, c kunye nemetadata iqulathe amakhonkco kwezi bhloko. Xa sinefayile yesibini .vbk, ilungele ukuhamba kwaye iqulethwe iibhloko a, b kunye ne-d, thina, sihlalutya isalathisi sokuchithwa kwamanzi, siyaqonda ukuba i-block d kuphela kufuneka idluliselwe. Kwaye ifayile yayo yemethadatha iya kuba nekhonkco kwiibhloko ezimbini zangaphambili kunye nenye entsha.

Ngokufanelekileyo, inkqubo yokuzalisa ezi zithuba zingenanto emva ngedatha ibizwa ngokuba yi-rehydration. Isele isebenzisa i-rehydration index yayo, esekelwe kwifayile ye-.vbk endala kumlinganiselo wokusebenza kwendawo. Okokuthi, ukuba umsebenzisi ufuna ukubuyisela ifayile ukusuka kuluhlu lokudubula umthamo, siqala ukudala isalathisi seebhloko ze-backup endala kakhulu kwaye sidlulisele kuphela iibhloko ezingekhoyo kwigalari yokudubula umthamo. Kwimeko evezwe emfanekisweni, ukwenzela ukubuyisela kwakhona i-FullBackup1.vbk ngokwe-rehydration index, sifuna kuphela ibhloko ye-C, esiyithathayo kuluhlu lokudubula umthamo. Ukuba into yokugcina ilifu isebenza njengoluhlu lokudubula, oku kukuvumela ukuba wonge imali eninzi.

Apha kunokubonakala ngathi le teknoloji iyafana naleyo isetyenziswa kwi-WAN Accelerators, kodwa kubonakala kunjalo kuphela. Kwi-accelerators, uphindaphindo lwelizwe jikelele; apha, uphinda-phindo lwasekhaya lusetyenziswa ngaphakathi kwefayile nganye kwi-offset ethile. Oku kwenzeka ngenxa yomahluko kwimisebenzi esonjululwayo: apha kufuneka sikhuphele iifayile ezinkulu ezipheleleyo ezigciniweyo, kwaye ngokutsho kophando lwethu, nokuba kudlula ixesha elide phakathi kwabo, le algorithm yokuqhawula inika esona siphumo silungileyo.

Kodwa ngakumbi izalathisi kuthixo wezalathisi! Kukho kwakhona isalathiso sokubuyisela idatha! Xa siqala ukubuyisela umatshini obekwe kwidash yomthamo, siya kufunda kuphela iibhloko zedatha ezizodwa ezingekho kwisikhewu sokusebenza.

Ingaba yenzeke njani?

Kuphelele apho kwintshayelelo. Ineenkcukacha ezininzi, kodwa njengoko kukhankanyiwe ngasentla, ngaphandle kwezi nkcukacha akunakukwazi ukuchaza indlela imisebenzi emitsha esebenza ngayo. Ke ngoko, ngaphandle kokuphazamiseka, makhe siqhubele phambili kweyokuqala.

Imowudi yokukopa

Ikakhulu isekelwe kubuchwephesha obukhoyo, kodwa ithwala ingqiqo eyahlukileyo yokusetyenziswa. 

Injongo yale ndlela kukuqinisekisa ukuba yonke idatha ebekwe kwindawo yendawo inekopi kwidash yomthamo.

Ukuba uthelekisa iimowudi zokuHambisa kunye noKhuphela entloko, iya kujongeka ngolu hlobo:

• Litsheyini elitywiniweyo kuphela elinokushenxiswa. Kwimeko yendlela yokukopisha, yonke into idluliswa, kungakhathaliseki ukuba kwenzekani kumsebenzi wokugcina.
• Ukushukuma kuqalwa xa iifayile zihamba ngaphaya kwemida yefestile yogcino lokusebenza, kwaye ukukopa kuqalwa nje ukuba ifayile yogcino ibonakala.
• Ukubekw'esweni kwedatha entsha yokukopa kwenzeka rhoqo, kwaye ukuyihambisa kwakusenziwa kanye kwiiyure ezi-4.

Ekuqwalaseleni imo entsha, ndiphakamisa ukuhamba kwimizekelo elula ukuya kweyinkimbinkimbi.

Kwimeko eqhelekileyo, sineefayile ezintsha ezinonyuso, kwaye sizikhuphela ngokulula kuluhlu lokufota. Kungakhathaliseki ukuba yeyiphi indlela esetyenziswayo kumsebenzi wokulondoloza, kungakhathaliseki ukuba iyingxenye etywiniweyo yekhonkco okanye hayi, kungakhathaliseki ukuba ifestile yethu yokusebenza iphelile. Bayithatha nje bayikhuphela.

Inkqubo esemva koku kukuphelelwa ngamanzi emzimbeni njengoko kuchaziwe ngasentla. Kwimo yokukopisha, ikwaqinisekisa ukuba asikhupheli iibhloko esele zikwindawo yokugcina. Ukwahlukana kuphela kukuba ukuba kwimodi ye-movie sitshintshe iifayile zangempela ngeefayile ze-dummy, apha asizichukumisi nangayiphi na indlela kwaye sishiye yonke into njengoko injalo. Ngaphandle koko, isalathiso sokuphelelwa ngamanzi emzimbeni, esizama ngononophelo ukugcina imali kunye nexesha lakho.

Umbuzo uvela - ukuba ujonga i-UI, kukho ithuba lokukhetha zombini iinketho ngaxeshanye. Ingaba imowudi edityanisiweyo enjalo iya kusebenza njani?

Makhe siqonde.

Isiqalo sisemgangathweni: ifayile yokugcina yenziwe kwaye ikopishwe ngokukhawuleza. Ukunyuswa kwenzelwe kuyo kwaye kukopishwe kwakhona. Oku kwenzeka kude kube ngumzuzu xa siqaphela ukuba iifayile zishiye ifestile yethu yokusebenza kwaye ikhonkco elitywiniweyo livele. Ngeli xesha senza umsebenzi wokuphelelwa ngamanzi emzimbeni kwaye sitshintshe ezi fayile ngeefayile ze-dummy. Ngokuqinisekileyo, asikhupheli nto kwakhona kuluhlu lokufota umthamo.

Yonke le ngqiqo inomdla inoxanduva lwebhokisi enye yokukhangela kwi-interface: Khuphela i-backups kwindawo yokugcina into nje ukuba zenziwe.

Kutheni le nto sifuna le ndlela yokuKhuphela?

Kungcono ukuphinda uphendule lo mbuzo ngale ndlela: yeyiphi imingcipheko esikhuselwe kuyo ngoncedo lwayo? Yeyiphi ingxaki esinceda siyisombulule?

Impendulo icacile: kunjalo, oku kukubuyisela idatha. Ukuba sinekopi epheleleyo yedatha yendawo kwindawo yokugcina into, ngoko kungakhathaliseki ukuba kwenzekani kwimveliso yethu, sinokuhlala sibuyisela idatha kwiifayile ezibekwe kwi-Amazon enemiqathango.

Ngoko makhe sidlule kwiimeko ezinokwenzeka, ukusuka kwezona zilula ukuya kwezona zintsokothileyo.

Ishwangusha elilula elinokuthi liwele kwiintloko zethu kukungafumaneki kwenye yeefayile kwikhonkco eligcinayo.

Ibali elibuhlungu lelokuba enye yemilinganiselo yendawo yethu yokugcina ye-SOBR yaphuka.

Iba mbi ngakumbi xa yonke indawo yokugcina ye-SOBR ingafikeleleki, kodwa uluhlu lokudubula lwamandla luyasebenza.
Kwaye yonke into imbi ngokwenene - oku kuxa iseva yogcino isifa kwaye umnqweno wakho wokuqala kukuzama ukubaleka kumda waseCanada ngemizuzu elishumi.

Ngoku makhe sijonge imeko nganye ngokwahlukeneyo.

Xa siphulukene nenye (kunye nezininzi) iifayile ezigcinayo, ke konke ekufuneka sikwenzile kukuqala inkqubo yokuskena indawo yokugcina, kwaye ifayile elahlekileyo iya kutshintshwa ngefayile eyidummy. Kwaye usebenzisa inkqubo yokubuyisela amanzi emzimbeni (eyaxutyushwa ekuqaleni kwenqaku), umsebenzisi uya kukwazi ukukhuphela idatha ukusuka kuluhlu lokudubula umthamo kwindawo yokugcina indawo.

Ngoku le meko intsonkothile. Masicinge ukuba i-SOBR yethu iqulathe imilinganiselo emibini esebenza kwimowudi yokuSebenza, nto leyo ethetha ukuba i-.vbk yethu kunye .vib zisasazwe phezu kwazo kumaleko angalinganiyo. Kwaye ngexesha elithile, enye yemilinganiselo ayifumaneki, kwaye umsebenzisi kufuneka abuyisele umatshini ngokukhawuleza, inxalenye yedatha elele ngokuchanekileyo kulo mgangatho.

Umsebenzisi uqalisa i-wizard yokubuyisela, ukhetha indawo afuna ukuyibuyisela kuyo, kwaye i-wizard, ngelixa isebenza, ifika ekuqondeni ukuba ayinayo yonke idatha eyimfuneko yokubuyisela kwindawo kwaye ngoko kufuneka ikhutshelwe kwi-capacity shooting. igalari. Kwangaxeshanye, iibhloko ezisele kugcino lwendawo aziyi kukhutshelwa kwilifu. Uzuko kwisalathisi sokubuyisela (ewe, kwakukhankanywe kwakhona ekuqaleni kwenqaku).

I-subtype yale meko kukuba yonke indawo yokugcina ye-SOBR ayizange ifikeleleke. Kule meko, asinanto yokukopisha kwindawo yokugcina indawo, kwaye zonke iibhloko zikhutshelwa kwilifu.

Kwaye eyona meko inomdla kukuba iseva yogcino yafa. Kukho iinketho ezimbini apha: umlawuli mkhulu kwaye wenza uqwalaselo backups, kwaye admin i Pinocchio ububi ngokwakhe kwaye akazange enze uqwalaselo backups.

Kwimeko yokuqala, kuya kukwanela ukuba abeke ngokulula ufakelo olucocekileyo lweVBR kwindawo ethile kwaye abuyisele idatabase yayo kwi-backup usebenzisa iindlela eziqhelekileyo. Ekupheleni kwale nkqubo, yonke into iya kubuyela kwisiqhelo. Okanye iya kubuyiselwa ngokuhambelana nenye yeemeko ezingentla.

Kodwa ukuba umlawuli ulutshaba lwakhe, okanye i-backup yoqwalaselo nayo inengxaki yokungaphumeleli, ngoko ke nalapha asizukumshiya kwinceba yelishwa. Kule meko, siye sazisa inkqubo entsha ebizwa ngokuba nguGcino Lwento yokuNgenisa ngaphandle. Ikuvumela ukuba utsibe inkqubo yokwenza kwakhona ngesandla indawo yokugcina ye-SOBR kwaye uncamathisele umthamo wokudubula kuyo kunye nokuphinda kuphindwe kwakhona, kwaye wongeze nje into yokugcina kwi-interface ye-Vim kwaye uqhube inkqubo yokuGcinwa kweNdawo yokuGcina. Ekuphela kwento enokuma endleleni phakathi kwakho kunye nee-backups zakho sisicelo sokungena igama eliyimfihlo ukuba ii-backups zakho zifihliwe.

Oku mhlawumbi konke malunga neNdlela yokuKhuphela kwaye siqhubela phambili

Imowudi etywiniweyo

Ingcinga ephambili yeyokuba ii-backups ezintsha azinakubonakala kubungakanani obukhethiweyo be-SOBR yendawo yokugcina. Ngaphambi kwe-v10, sasineModi yoLondolozo kuphela, xa nawuphi na umsebenzi kunye novimba wawuthintelwe ngokupheleleyo. Uhlobo lwemowudi eqinileyo yokuvala ugcino, apho kuphela iqhosha lokuPhuma likhoyo, elithutha i-backups ukuya kwelinye inqanaba ngexesha elinye.

Kwaye imowudi etywiniweyo luhlobo lwenketho "ethambileyo": siyakwalela ukwenziwa kwee-backups ezintsha kwaye ngokuthe ngcembe sicima ezindala ngokugcinwa okukhethiweyo, kodwa kwinkqubo asiphulukani amandla okubuyisela kumanqaku agciniweyo. Into eluncedo kakhulu xa sinokuba nesiqwenga se-hardware esisondela ekupheleni kobomi bayo kwaye sifuna ukuyibuyisela endaweni yayo, okanye sifuna ukuyikhulula nje into ebaluleke kakhulu, kodwa akukho ndawo yokuyithatha kwaye uhambise yonke into kanye. Okanye ayinakususwa.

Ngako oko, umgaqo wokusebenza ulula kakhulu: kuyimfuneko ukuvala yonke imisebenzi yokubhala (ukubonakala kwedatha entsha), ukushiya ukufunda (ukubuyisela) kunye nokucima (ukugcinwa).

Zombini ezi modi zingasetyenziswa ngaxeshanye, kodwa khumbula ukuba uLondolozo lunokubaluleka okuphezulu.

Njengomzekelo, qwalasela i-SOBR ebandakanya imilinganiselo emibini. Makhe sicinge ukuba kwiintsuku ezine zokuqala senze i-backups kwimowudi yokuPhambili ngoNaphakade, kwaye emva koko sitywina ubungakanani.Oku kukhokelela kwinto yokuba siqalise ukudala okutsha okusebenzayo ngokupheleleyo kwinqanaba lesibini elikhoyo. Ukuba ukugcinwa kwethu kusine, ngoko xa lonke ikhonkco elibekwe kumda otywiniweyo lingaphaya kwemida yalo, liyacinywa ngesazela esicocekileyo.

Kukho iimeko xa ukucinywa kwenzeka kwangaphambili. Umzekelo, oku kuPhambili ngokunyuka ngokugcwala kwexesha. Ukuba senze i-backups epheleleyo kwiintsuku ezimbini zokuqala, kwaye ngoLwesine sigqiba ekubeni sitywine indawo yokugcina, ngoko ngoLwesihlanu, xa kusenziwa i-backup entsha, ifayile ngoMvulo iya kususwa ngenxa yokuba. akukho zixhomekeke kule nqanaba. Kwaye ingongoma ngokwayo ayixhomekeke nakubani na. Emva koko silinda kude kube namanqaku amane adalwe kwinqanaba elikhoyo kwaye ucime ezintathu eziseleyo, ezingenakususwa ngokuzimeleyo komnye nomnye.

Izinto zilula ngeReverse Incremental. Kuyo, amanqaku amadala awaxhomekeke kuyo nantoni na kwaye anokususwa ngokukhuselekileyo. Ngoko ke, ngokukhawuleza ukuba i-vbk entsha yenziwe kwinqanaba elitsha, i-.vrbs endala iya kucinywa nganye nganye.

Ngendlela, kutheni sidala entsha .vbk rhoqo: ukuba asizange siyidale, kodwa saqhubeka ikhonkco elidala lokunyuka, ngoko i-.vbk endala yayiza kukhenkcela ixesha elide elingenasiphelo kuyo nayiphi na indlela, ukukhusela ukucima kwayo. Ke ngoko, kwagqitywa ekubeni kamsinya nje ukuba ubungakanani butywinwe, senze i-backup epheleleyo kumda wasimahla.

Izinto zinzima ngakumbi ngoluhlu lokudubula umthamo.

Okokuqala, makhe sijonge imowudi yokukhuphela. Masicinge ukuba besisenza ii-backups ngenkuthalo iintsuku ezine, kwaye ke uluhlu lokudubula lwavalwa. Asicimi nantoni na, kodwa ngokuthobeka sinyamezele ukugcinwa, emva koko sisusa idatha kuluhlu lokudubula umthamo.

Ngokumalunga nento efanayo eyenzekayo kwimodi yokuhamba - silindele ukuphinda sithintelwe, cima endala kwindawo yokugcina indawo, kwaye ucime leyo igcinwe kwindawo yokugcina into.

Umzekelo onomdla nge-Forever forward incremental. Sifaka ukugcinwa kumanqaku amathathu kwaye siqale ukwenza i-backups ngoMvulo, ezikhutshelwa rhoqo kwifu. Emva kokutywinwa kokugcinwa, i-backups iyaqhubeka nokudalwa, igcina amanqaku amathathu, kodwa idatha egcinwe kwi-dash yamandla ihlala ixhomekeke kwaye ayikwazi ukususwa. Ngoko ke, silinda kude kube ngoLwesine, xa .vbk yethu idlula ukugcinwa, kwaye kuphela emva koko sicima ngokuzolileyo lonke ikhonkco eligciniweyo.

Kwaye i-disclaimer encinci: yonke imizekelo apha iboniswe ngomatshini omnye. Ukuba unazo ezininzi kwi-backup yakho, ke ukuphinda kuchukunyiswe kwakhona kuya kwahluka ngokuxhomekeke ekubeni i-Active Full yenziwa okanye hayi.

Yiloo nto kuphela ekhoyo kuyo. Ke masiqhubele phambili kweyona nto inzima kakhulu-

Ukungakhuseleki

Njengamanqaku angaphambili, into yokuqala kukuba yintoni ingxaki esonjululwa ngulo msebenzi. Ngokukhawuleza ukuba silayishe ii-backups zethu kwindawo ethile yokugcina, kukho umnqweno onamandla wokuqinisekisa ukhuseleko lwabo, oko kukuthi, ukuthintela ngokwasemzimbeni ukucima kunye naluphi na ukuguqulwa ngexesha lokugcinwa okunikiweyo. Kubandakanya ii-admins, kubandakanywa phantsi kweeakhawunti zabo zeengcambu. Oku kukuvumela ukuba ubakhusele emonakalweni wengozi okanye ngabom. Nabani na osebenza nge-AWS usenokuba ufumene into efanayo ebizwa ngokuba yi-Object Lock.

Ngoku makhe sijonge imo ngokwemigaqo ngokubanzi, kwaye emva koko sijonge kwiinkcukacha. Kumzekelo wethu, Ukungaguquki kuya kwenziwa kuluhlu lwethu lokudubula ngokugcinwa kweentsuku ezine. Kwaye i Copy mode yenziwe kwi-backup.

Ukungaguquki akudibanisi nokugcinwa ngokubanzi nangayiphi na indlela. Umzekelo, ayongezi amanqaku angaphezulu okanye nantoni na enjalo. Kuphela nje umntu akanako ukucima iifayile zogcino phakathi kweentsuku ezine. Ukuba wenza i-backup ngoMvulo, uya kukwazi ukucima ifayile yayo kuphela ngoLwesihlanu.

Zonke iikhonsepthi ezichazwe ngaphambili zokuphelelwa ngamanzi emzimbeni, izalathisi kunye nemetadata ziyaqhubeka nokusebenza ngokufanayo. Kodwa ngemeko enye - ibhloko ayisetyenzisiweyo kuphela kwidatha, kodwa kunye nemetadata. Oku kwenziwa xa umhlaseli onobuqhophololo egqiba kwelokuba acime idatabase yethu yemetadata kunye nokuthintela iibhloko zedatha ukuba zijike zibe yimush yokubini engenamsebenzi.

Ngoku lixesha elihle lokuchaza iteknoloji yethu yokuvelisa ibhloko. Okanye ukuveliswa kwebhlokhi. Ukwenza oku, qwalasela imeko eyakhokelela ekuveleni kwayo.

Masithathe isikali sexesha leentsuku ezintandathu kwaye ngaphantsi siya kuphawula ixesha lokuphelelwa okulindelweyo kokungaguquki. Ngosuku lokuqala sithatha kwaye senze ifayile equkethe ibhloko yedatha kunye nemethadatha yayo. Ukuba ukungaguquki kumiselwe kwiintsuku ezintathu, kunengqiqo ukucinga ukuba ngosuku lwesine idatha iya kuvulwa kwaye isuswe. Ngosuku lwesibini siya kongeza ifayile2 entsha, equka ibhloko b enezicwangciso ezifanayo. I-block a isafuna ukususwa ngosuku lwesine. Kodwa ngosuku lwesithathu kwenzeka into embi - ifayile yeFayile3 yenziwe, equka ibhloko entsha d kunye nekhonkco kwibhloko endala a. Oku kuthetha ukuba kwibhloko kunye neflegi yayo yokungaguquki kufuneka ibuyiselwe kumhla omtsha, otshintshelwe kumhla wesithandathu. Kwaye nantsi ingxaki ivela - kwii-backups zangempela kukho inani elikhulu leebhloko ezinjalo. Kwaye ukuze kwandiswe ixesha labo lokungaguquki, kufuneka wenze inani elikhulu lezicelo ngexesha ngalinye. Kwaye eneneni, le iya kuba yinkqubo yemihla ngemihla ephantse ingapheli, kuba ngenqanaba eliphezulu lokunokwenzeka siya kufumana iibhloko ezikhutshiweyo kwikopi nganye. Lithetha ukuthini inani elikhulu lezicelo ezivela kubaboneleli bezinto zokugcina? Kunene! Ityala elikhulu ekupheleni kwenyanga.

Kwaye ukuze ungavezi abaxhasi bakho abathandayo ngemali eninzi, kwayilwa indlela yokuvelisa ibhlokhi. Eli lixesha elongezelelweyo esongeza kwixesha elimiselweyo lokungaguquki. Kulo mzekelo ungezantsi, eli xesha ziintsuku ezimbini. Kodwa lo ngumzekelo nje. Ngokwenyani, basebenzisa eyabo ifomula, enika malunga neentsuku ezilishumi ezongezelelweyo ngexesha lokutshixa kwenyanga.

Masiqhubeke siqwalasela imeko efanayo, kodwa nge-block block. Ngosuku lokuqala senza ifayile1 kwibhloko a kunye nemetadata. Songeza ixesha lesizukulwana kunye nokungaguquki - oku kuthetha ukuba ithuba lokucima ifayile liya kuba ngomhla wesithandathu. Ukuba ngosuku lwesibini senza iFayile2, equka ibhloko b kunye nekhonkco ukubhloka a, ngoko akukho nto eyenzekayo kumhla olindelekileyo wokucima. Wema njengoko wenzayo ngomhla wesithandathu. Kwaye ngoko sizama ukugcina imali kwinani lezicelo. Imeko kuphela xa umhla wokugqibela unokutshintshwa ukuba ixesha lesizukulwana liphelile. Oko kukuthi, ukuba ngosuku lwesithathu iFayile3 entsha iqulethe ikhonkco lokuvimba a, ngoko isizukulwana se-2 siya kongezwa ekubeni iGen1 sele iphelelwe lixesha. Kwaye umhla olindelekileyo wokucima ibhloko uya kutshintshela kusuku lwesibhozo. Oku kusivumela ukuba sinciphise ngokukhawuleza inani lezicelo zokwandisa ixesha lokuphila kweebhloko ezichithwayo, ezigcina abathengi itoni yemali.

Itekhnoloji ngokwayo iyafumaneka kubasebenzisi be-S3 kunye ne-S3-ehambelana ne-hardware, abavelisi babo baqinisekisa ukuba ukuphunyezwa kwabo akufani ne-Amazon. Ke ngoko impendulo yombuzo osemthethweni wokuba kutheni i-Azure ingaxhaswanga - banento efanayo, kodwa isebenza kwinqanaba lezikhongozeli, hayi izinto ezizimeleyo.
