Kutheni kufuneka wenze i-backups? Emva kwayo yonke loo nto, izixhobo zithembeke kakhulu, kwaye ngaphandle koko, kukho "amafu" angcono ekuthembekeni kunamaseva abonakalayo: ngolungelelwaniso olufanelekileyo, iseva "yelifu" inokusinda ngokulula ukusilela kwesiseko somncedisi, kwaye ukusuka. indawo yokujonga abasebenzisi benkonzo, kuya kubakho ukutsiba okuncinci, okungabonakaliyo kwinkonzo yexesha. Ukongeza, ukuphinda-phindwa kolwazi kudla ngokufuna ukuhlawulela ixesha "elilongezelelweyo" leprosesa, umthwalo wediski, kunye netrafikhi yenethiwekhi.
Inkqubo efanelekileyo iqhuba ngokukhawuleza, ayivuzi imemori, ayinamingxuma, kwaye ayikho.
-Akwaziwa
Ekubeni iinkqubo zisabhalwa ngabaphuhlisi beeprotheyini, kwaye ngokuqhelekileyo akukho nkqubo yokuvavanya, kunye neenkqubo azifane zihanjiswe kusetyenziswa "iinkqubo ezilungileyo" (nazo ngokwazo ziyiprogram kwaye ngenxa yoko zingafezekanga), abalawuli benkqubo bahlala besombulula iingxaki ezivakalayo ngokufutshane kodwa ngokufutshane: "buyela kwindlela ebiyiyo", "zisa isiseko ekusebenzeni okuqhelekileyo", "isebenza kancinci - buyela umva", kunye nento endiyithandayo "Andazi, kodwa yilungise".
Ukongeza kwiimpazamo ezinengqiqo ezivelayo ngenxa yomsebenzi wokungakhathali wabaphuhlisi, okanye indibaniselwano yeemeko, kunye nolwazi olungaphelelanga okanye ukungaqondi kakuhle kweempawu ezincinci zeenkqubo zokwakha - kuquka ukudibanisa kunye nenkqubo, kuquka iinkqubo zokusebenza, abaqhubi kunye ne-firmware - kukho nezinye iimpazamo. Ngokomzekelo, abaninzi abaphuhlisi baxhomekeke kwixesha lokuqhuba, belibala ngokupheleleyo ngemithetho yendalo, engenakukwazi ukujikeleza usebenzisa iinkqubo. Oku kubandakanya ukuthembeka okungapheliyo kwesistim esezantsi yediski kwaye, ngokubanzi, nayiphi na inkqubo esezantsi yokugcina idatha (kubandakanya i-RAM kunye ne-cache yeprosesa!), kunye nexesha lokucutshungulwa kwe-zero kwiprosesa, kunye nokungabikho kweempazamo ngexesha lokuhanjiswa kwenethiwekhi kunye nexesha lokucubungula kwiprosesa. iprosesa, kunye ne-network latency, elingana no-0. Akufanele ungawuhoyi umhla wokugqibela owaziwayo, kuba ukuba awuyi kudibana nayo ngexesha, kuya kuba neengxaki ezimbi ngakumbi kunee-nuances zenethiwekhi kunye nokusebenza kwediski.
Yintoni enokuyenza ngeengxaki eziphakama ngamandla kwaye zijinga phezu kwedatha ebalulekileyo? Akukho nto ithatha indawo yabaphuhlisi abaphilayo, kwaye ayisiyonyani ukuba iyakwenzeka kwixesha elizayo elingekude. Ngakolunye uhlangothi, kuphela iiprojekthi ezimbalwa eziye zaphumelela ekuqinisekiseni ngokupheleleyo ukuba inkqubo iya kusebenza njengoko bekucetywayo, kwaye akuyi kuba nako ukuthabatha nokusebenzisa ubungqina kwezinye iiprojekthi ezifanayo. Kwakhona, ubungqina obunjalo buthatha ixesha elininzi kwaye bufuna izakhono ezikhethekileyo kunye nolwazi, kwaye oku kunciphisa amathuba okusetyenziswa kwabo kuthathelwa ingqalelo imihla ebekiweyo. Ukongeza, asikayazi indlela yokusebenzisa itekhnoloji ekhawulezayo, engabizi kwaye ethembeke ngokungenasiphelo ukugcina, ukusetyenzwa kunye nokuhambisa ulwazi. Ubuchwephesha obunjalo, ukuba bukhona, bukwimo yeengqikelelo, okanye - ngokuqhelekileyo - kuphela kwiincwadi zesayensi kunye neefilimu.
Amagcisa amahle akhuphela, amagcisa abalaseleyo abile.

Ezona zisombululo ziphumeleleyo kunye nezinto ezilula ngokumangalisayo zihlala zisenzeka apho iikhonsepthi, itekhnoloji, ulwazi, kunye neenkalo zesayensi ezingahambelaniyo xa uqala nje ukuhlangana.
Ngokomzekelo, iintaka kunye neenqwelo-moya zinamaphiko, kodwa nangona ukufana okusebenzayo - umgaqo wokusebenza kwezinye iindlela ziyafana, kwaye iingxaki zobuchwepheshe zixazululwa ngendlela efanayo: amathambo angenalutho, ukusetyenziswa kwezinto ezinamandla kunye nezilula, njl. iziphumo zahluke ngokupheleleyo, nangona zifana kakhulu. Imizekelo emihle kakhulu esiyibonayo kwiteknoloji yethu nayo ibolekwe kakhulu kwindalo: amacandelo acinezelekileyo eenqanawa kunye ne-submarines yi-analogue ngqo kunye ne-annelids; ukwakha uhlaselo kunye nokujonga ingqibelelo yedatha - ukuphindaphinda ikhonkco leDNA; kunye nezitho ezidibeneyo, ukuzimela komsebenzi wamalungu ahlukeneyo ukusuka kwinkqubo ye-nervous central (automation of heart) kunye ne-reflexes - iinkqubo ezizimeleyo kwi-Intanethi. Ngokuqinisekileyo, ukuthatha kunye nokusebenzisa izisombululo esele zenziwe "intloko-on" igcwele iingxaki, kodwa ngubani owaziyo, mhlawumbi azikho ezinye izisombululo.
Akwaba bendisazi apho uya kuwa khona, ngendikwandlala iindiza!

Oku kuthetha ukuba iikopi zokugcina zibalulekile kwabo bafuna:
- Ukwazi ukubuyisela ukusebenza kweenkqubo zakho ngexesha elincinci lokuphumla, okanye ngaphandle kwalo konke
- Yenza ngesibindi, kuba xa kukho impazamo kusoloko kukho ithuba lokubuyisela umva
- Nciphisa iziphumo zorhwaphilizo lwedatha ngabom
Nantsi ithiyori encinci
Naluphi na ulwahlulo alunasizathu. Indalo ayicaluli. Sihlela kuba silungele ngakumbi. Kwaye sihlela ngokwedatha esiyithatha ngokungenasizathu.
βUJean Bruler
Kungakhathaliseki ukuba yeyiphi indlela yokugcina idatha, ukugcinwa kwedatha enengqiqo kunokwahlulwa ngeendlela ezimbini zokufikelela kule datha: ibhloko kunye nefayile. Olu lwahlulo kutshanje luye lwaphazamiseka kakhulu, kuba ibhloko ecocekileyo, kunye nefayile ecocekileyo, ukugcinwa okunengqiqo akukho. Nangona kunjalo, ukwenza lula, siya kucinga ukuba zikhona.
Vimba ukugcinwa kwedatha kuthetha ukuba kukho isixhobo somzimba apho idatha ibhalwe kwiindawo ezithile ezisisigxina, iibhloko. Iibhloko zifikelelwa kwidilesi ethile; ibhloko nganye inedilesi yayo ngaphakathi kwesixhobo.
Ugcino lwenziwa ngokukopa iibhloko zedata. Ukuqinisekisa ukuthembeka kwedatha, ukurekhodwa kweebhloko ezintsha, kunye notshintsho kwizinto ezikhoyo, zimisiwe ngexesha lokukopisha. Ukuba sithatha isifaniso kwihlabathi eliqhelekileyo, eyona nto ikufutshane ligumbi elineeseli ezinamanani afanayo.
Ukugcinwa kwedatha yefayile ngokusekelwe kumgaqo wesixhobo esinengqiqo kukufutshane nokugcinwa kwebhlokhi kwaye ihlala icwangciswa phezulu. Umahluko obalulekileyo bubukho bolawulo lwendawo yokugcina kunye namagama afundeka ngabantu. I-abstraction inikezelwa ngendlela yefayile - indawo yedatha ebizwa ngokuba yi-directory, kunye ne-directory - ifayile ekhethekileyo apho iinkcazo kunye nokufikelela kwezinye iifayile zigcinwa. Iifayile zinokubonelelwa ngemethadatha eyongezelelweyo: ixesha lokudala, iiflegi zokufikelela, njl. Ii-backups zihlala zenziwe ngolu hlobo: zijonga iifayile ezitshintshileyo, emva koko zikopishe kwenye indawo yokugcina ifayile enesakhiwo esifanayo. Ingqibelelo yedatha ngokuqhelekileyo iphunyezwa ngokungabikho kweefayile ezibhaliweyo. Imetadata yefayile igcinwe ngendlela efanayo. Owona mzekeliso usondeleyo lithala leencwadi, elinamacandelo aneencwadi ezahlukeneyo, kananjalo linekhathalogu enamagama eencwadi anokufundwa ngabantu.
Kungekudala, enye inketho ichazwa ngamanye amaxesha, apho, ngokomgaqo, ukugcinwa kwedatha yefayile kwaqala, kwaye eneempawu ezifanayo zakudala: ukugcinwa kwedatha yento.
Ihluke ekugcinweni kwefayile kuba ayinayo i-nesting engaphezu kweyodwa (i-flat scheme), kwaye amagama eefayile, nangona afundeka ngabantu, asafaneleka ngakumbi ukuqhutyelwa ngoomatshini. Xa usenza i-backups, ukugcinwa kwezinto kudla ngokuphathwa ngokufanayo nokugcinwa kweefayile, kodwa ngamanye amaxesha kukho ezinye iinketho.
- Kukho iindidi ezimbini zabalawuli benkqubo, abo bangenzi i-backups, kunye nabo ESELE besenza.
- Enyanisweni, kukho iintlobo ezintathu: kukho nabo bajonga ukuba ii-backups zinokubuyiswa.-Akwaziwa
Kukwafanelekile ukuqonda ukuba inkqubo yogcino lwedatha ngokwayo iqhutywa ziinkqubo, ngoko ke inazo zonke izinto ezingeloncedo njengayo nayiphi na enye inkqubo. Ukususa (kungekhona ukuphelisa!) Ukuxhomekeka kwinto yomntu, kunye neempawu - ezizimeleyo ezingenayo impembelelo enamandla, kodwa kunye inokunika umphumo obonakalayo - okubizwa ngokuba umthetho 3-2-1. Kukho iinketho ezininzi zendlela yokuyicacisa, kodwa ndithanda ukutolikwa okulandelayo ngcono: iiseti ze-3 zedatha efanayo kufuneka zigcinwe, iiseti ze-2 kufuneka zigcinwe kwiifomathi ezahlukeneyo, kwaye isethi ye-1 kufuneka igcinwe kwindawo yokugcina indawo ekude.
Indlela yokugcina kufuneka iqondwe ngolu hlobo lulandelayo:
- Ukuba kukho ukuxhomekeka kwindlela yokugcina umzimba, sitshintsha indlela yomzimba.
- Ukuba kukho ukuxhomekeka kwindlela yokugcina enengqiqo, sitshintsha indlela enengqiqo.
Ukufezekisa umphumo ophezulu womgaqo we-3-2-1, kuyacetyiswa ukuba utshintshe ifomathi yokugcina kuzo zombini iindlela.
Ukusuka kwindawo yokujonga ukulungelelaniswa kwenjongo ekujoliswe kuyo - ukubuyisela ukusebenza - ulwahlulo lwenziwa phakathi kwee-backups "ezishushu" kunye "ezibandayo". Ezishushu zihluke kwizinto ezibandayo kwinto enye kuphela: zilungele ukusetyenziswa ngokukhawuleza, ngelixa ezibandayo zifuna amanyathelo ongezelelweyo okubuyisela: ukuchithwa, ukutsalwa kwi-archive, njl.
Sukubhidanisa iikopi ezishushu nezibandayo kunye neekopi ze-intanethi kunye ne-offline, ezithetha ukwahlulwa ngokwasemzimbeni kwedatha kwaye, enyanisweni, lolunye uphawu lokuhlelwa kweendlela zokugcina. Ngoko ikopi engaxhunyiwe kwi-intanethi-engaqhagamshelwanga ngokuthe ngqo kwinkqubo apho kufuneka ibuyiselwe khona-inokuba ishushu okanye ibanda (ngokwemiqathango yokulungela ukubuyisela). Ikopi ye-intanethi inokufumaneka ngokuthe ngqo apho idinga ukubuyiselwa, kwaye ininzi idla ngokutshisa, kodwa kukho nezibandayo.
Ukongeza, ungalibali ukuba inkqubo yokwenza iikopi zogcino ngokwalo ngokuqhelekileyo ayipheli ngokudala ikopi enye yogcino, kwaye kunokubakho inani elikhulu leekopi. Ngoko ke, kuyimfuneko ukwahlula phakathi kwe-backups epheleleyo, i.e. ezo zinokubuyiselwa ngokuzimeleyo kwezinye ii-backups, kunye nokwahluka (ukunyuka, ukuhlukana, ukuhla, njl.)
Ii-backups ezongeziweyo ezongezelelweyo ziinzame zokugcina indawo yokugcina i-backup. Ngaloo ndlela, kuphela idatha etshintshileyo esuka kwi-backup yangaphambili ibhaliwe kwikopi yokugcina.
Ezahlukeneyo ezicuthayo zenzelwe injongo enye, kodwa ngendlela eyahlukileyo kancinane: kwenziwa ikopi epheleleyo egciniweyo, kodwa umahluko kuphela phakathi kwekopi entsha kunye naleyo yangaphambili igcinwa ngokwenene.
Ngokwahlukileyo, kuyafaneleka ukuqwalasela inkqubo yokugcina i-backup phezu kokugcinwa, exhasa ukungabikho kokugcinwa kwezinto eziphindwe kabini. Ngaloo ndlela, ukuba ubhala ii-backups ezipheleleyo phezu kwayo, kuphela ukungafani phakathi kwee-backups kuya kubhalwa ngokwenene, kodwa inkqubo yokubuyisela i-backups iya kufana nokubuyisela kwikopi epheleleyo kunye nokucaca ngokupheleleyo.

Kuyinto engathandekiyo kakhulu xa kungekho zikopi ezigcinayo, kodwa kubi kakhulu ukuba ikopi yogcino ibonakala yenziwe, kodwa xa ibuyisela kwakhona kuvela ukuba ayinakubuyiselwa kuba:
- Ukunyaniseka kwedatha yomthombo kuye kwathotywa.
- Ugcino lokugcina lonakele.
- Ukubuyisela kusebenza kancinane kakhulu; awukwazi ukusebenzisa idatha efunyenwe ngokuyinxenye.
Inkqubo yokugcina igcinwe ngokufanelekileyo kufuneka ithathele ingqalelo izimvo ezinjalo, ngakumbi ezimbini zokuqala.
Ukunyaniseka kwedatha yomthombo kunokuqinisekiswa ngeendlela ezininzi. Ezona zisetyenziswa ngokuqhelekileyo zezi zilandelayo: a) ukwenza imifanekiso ekhawulezayo yesixokelelwano sefayile kwinqanaba lebhloko, b) βukukhenkcezaβ imeko yenkqubo yefayile, c) isixhobo esikhethekileyo sebhloko esinogcino lwenguqulelo, d) ukurekhodwa ngokulandelelana kweefayile okanye iibhloko. Ii-checksums nazo zisetyenziselwa ukuqinisekisa ukuba idatha iqinisekisiwe ngexesha lokubuyisela.
Urhwaphilizo kugcino lunokubonwa kusetyenziswa iitshekhi. Indlela eyongezelelweyo kukusetyenziswa kwezixhobo ezikhethekileyo okanye iinkqubo zefayile apho idatha esele irekhodiwe ayinakuguqulwa, kodwa ezintsha zingongezwa.
Ukukhawulezisa ukubuyiswa, ukubuyiswa kwedatha kusetyenziswa kunye neenkqubo ezininzi zokubuyisela - ngaphandle kokuba akukho mbhobho ngendlela yenethiwekhi ecothayo okanye inkqubo yedisk ecothayo. Ukujikeleza imeko ngedatha efunyenweyo ngokuyinxenye, ungayaphula inkqubo yogcino kwimisetyenzana encinci, nganye leyo yenziwa ngokwahlukeneyo. Ngaloo ndlela, kunokwenzeka ukubuyisela ukusebenza ngokuqhubekayo ngelixa uqikelela ixesha lokubuyisela. Le ngxaki idla ngokulala kwinqwelomoya yombutho (SLA), ngoko asiyi kuhlala kule nto ngokweenkcukacha.
Ingcali yeziqholo ayinguye owongeza kuzo zonke isitya, kodwa lowo ungongeza nantoni na eyongezelelweyo kuyo.

Izenzo malunga nesoftware esetyenziswa ngabalawuli benkqubo zinokwahluka, kodwa imigaqo jikelele isahleli, ngendlela enye okanye enye, iyafana, ngakumbi:
- Kucetyiswa ngamandla ukusebenzisa izisombululo esele zenziwe.
- Iinkqubo kufuneka zisebenze ngokuqikelelwayo, okt. Akufunekanga kubekho iimpawu ezingabhalwanga okanye imiqobo.
- Ukuseta inkqubo nganye kufuneka kube lula kangangokuba akufuneki ukuba ufunde incwadi okanye iphepha lokukopela ngalo lonke ixesha.
- Ukuba kunokwenzeka, isisombululo kufuneka sibe yindawo yonke, kuba abancedisi banokuhluka kakhulu kwiimpawu zabo zehardware.
Kukho ezi nkqubo zilandelayo eziqhelekileyo zokuthatha i-backups kwizixhobo zebhloko:
- dd, eyaziwayo kumagqala olawulo lwenkqubo, oku kukwaquka iinkqubo ezifanayo (efanayo dd_rescue, umzekelo).
- Izinto eziluncedo ezakhelwe kwezinye iinkqubo zefayile ezenza ukulahlwa kwendlela yefayile.
- izinto eziluncedo kakhulu; umzekelo i-partclone.
- Izigqibo ezizezakhe, ezidla ngokuba zezobunikazi; umzekelo, NortonGhost kwaye kamva.
Kwiinkqubo zefayile, ingxaki yokugcina isonjululwe ngokuyinxenye kusetyenziswa iindlela ezisebenzayo kwizixhobo zebhlokhi, kodwa ingxaki inokusonjululwa ngokufanelekileyo kusetyenziswa, umzekelo:
- Rsync, inkqubo yenjongo-jikelele kunye neprotocol yongqamaniso lwenkqubo yefayile.
- Izixhobo ezakhelwe ngaphakathi zokugcina (ZFS).
- izixhobo zogcino lweenkcukacha zomntu wesithathu; oyena mmeli udumileyo yitar. Kukho abanye, umzekelo, i-dar - indawo yetha ejoliswe kwiinkqubo zanamhlanje.
Kuyafaneleka ukukhankanya ngokwahlukeneyo malunga nezixhobo zesoftware zokuqinisekisa ukungaguquguquki kwedatha xa usenza iikopi zogcino. Olona khetho luqhele ukusetyenziswa lu:
- Ukunyuswa kwenkqubo yefayile kwimodi yokufunda kuphela (ReadOnly), okanye ukukhenkceza inkqubo yefayile (i-freeze) - indlela yokusetyenziswa okulinganiselweyo.
- Ukudala i-snapshots yesimo seenkqubo zefayile okanye izixhobo zebhloko (LVM, ZFS).
- Ukusetyenziswa kwezixhobo zeqela lesithathu ukulungiselela ukubonakaliswa, nakwiimeko apho amanqaku angaphambili awanakubonelelwa ngesizathu esithile (iiprogram ezifana ne-hotcopy).
- Indlela yokukhuphela-ngokutshintsha (CopyOnWrite), nangona kunjalo, ikholisa ukubotshelelwa kwindlela yefayile esetyenziswayo (BTRFS, ZFS).
Ke, kwiseva encinci kufuneka unikeze iskimu sokugcina esihlangabezana nezi mfuno zilandelayo:
- Kulula ukuyisebenzisa - akukho manyathelo ongezelelweyo awongezelelweyo afunekayo ngexesha lokusebenza, amanyathelo amancinci okudala nokubuyisela iikopi.
- Universal - isebenza kuzo zombini iiseva ezinkulu nezincinci; oku kubalulekile xa ukhulisa inani labancedisi okanye ukukala.
- Ifakwe ngumphathi wepakethe, okanye kumyalelo omnye okanye emibini efana "khuphela kwaye ukhuphe".
- Izinzile - ifomathi yokugcina esemgangathweni okanye ixesha elide isetyenzisiweyo.
- Ukukhawuleza emsebenzini.
