Eli nqaku lophononongo liyaqhubeka , ebhaliweyo ngesicelo sabafundi, iya kuthetha nge-UrBackup, BackupPC, kunye ne-AMANDA.
UrBackup uphononongo.
Ngesicelo somthathi-nxaxheba Ndiyongeza uphononongo lwe-UrBackup, inkqubo yokugcina iseva yomxhasi. Ikuvumela ukuba wenze i-backups epheleleyo kunye neyongeziweyo, inokusebenza kunye ne-snapshots yesixhobo (Win kuphela?), Kwaye unokwenza kwakhona iifayile zefayile. Umxhasi unokufumaneka kuthungelwano olufanayo nomncedisi, okanye aqhagamshele nge-Intanethi. Ukulandelwa kokutshintsha kubhengezwe, okukuvumela ukuba ufumane ngokukhawuleza umahluko phakathi kweekopi ezigcinayo. Kukwakho nenkxaso ye-server-side data deducation, egcina indawo. Uqhagamshelo lwenethiwekhi lunoguqulelo oluntsonkothileyo, kwaye kukho ujongano lwewebhu lokulawula umncedisi. Makhe sibone ukuba yintoni anokuyenza:
Kwimo yogcino olupheleleyo, ezi ziphumo zilandelayo zifunyenwe:

Ubungakanani bogcino kuzo zombini iimeko bebumalunga ne-14 GB, nto leyo ebonisa ukukhutshwa kokusebenza kwicala lomncedisi. Kufuneka kwakhona kuqatshelwe ukuba kukho ukungavisisani phakathi kwexesha lokudalwa kogcino kumncedisi kunye nomxhasi, obonakala ngokucacileyo kwiigrafu kwaye yibhonasi emnandi kakhulu, kuba ujongano lwewebhu lubonisa ixesha elisebenzayo lenkqubo yogcino kwi. icala lomncedisi ngaphandle kokuthathela ingqalelo
imeko yomxhasi. Ngokubanzi, iigrafu zeekopi ezipheleleyo kunye nezandisiweyo azibonakali. Umahluko kuphela mhlawumbi indlela ephathwa ngayo kwicala lomncedisi. Ndikwavuyiswa ngumthwalo ophantsi weprosesa kwinkqubo engafunekiyo.
Uphononongo lwe-BackupPC
Ngesicelo somthathi-nxaxheba Ndiyongeza uphononongo lwe-BackupPC. Le software ifakwe kwi-server yokugcina i-backup, ebhalwe kwi-perl, kwaye isebenza ngaphezulu kwezixhobo ezahlukeneyo zokulondoloza - ngokuyinhloko i-rsync, i-tar. I-Ssh kunye ne-smb zisetyenziswa njengezothutho; kukho kwakhona i-cgi-based interface yewebhu (ebekwe phezulu kwe-apache). Ujongano lwewebhu lunoluhlu olubanzi lwezicwangciso. Phakathi kweempawu kukukwazi ukuseta ixesha elincinci phakathi kwee-backups, kunye nexesha apho ii-backups zingayi kudalwa. Xa ukhetha inkqubo yefayile ye-server yogcino, kufuneka uqinisekise ukuba amakhonkco anzima ayaxhaswa. Ngaloo ndlela, inkqubo yefayile yokugcina ayinakwahlulwa ibe ngamanqaku okunyuka. Ngokubanzi, amava amnandi, makhe sibone ukuba le software iyakwazi ukwenza ntoni:
Kwimowudi yokudala i-backups epheleleyo nge-rsync, iziphumo ezilandelayo zifunyenwe:

Kwimowudi eyongeziweyo yokugcina, kuye kwafuneka ndiyilahle i-tar kuba ii-backups azizange zenziwe ngezi setingi.
Iziphumo zokwenza i-backups ezongeziweyo usebenzisa i-rsync zezi:

Ngokubanzi, i-rsync inenzuzo encinci yesantya i-rsync iphinda isebenze ngakumbi ngokwezoqoqosho kunye nenethiwekhi. Oku kunokulungiswa ngokuyinxenye kusetyenziso oluncinci lwe-CPU ngetar njengenkqubo yokugcina. Enye inzuzo ye-rsync kukuba isebenza kunye neekopi ezongezelelweyo. Ubungakanani bendawo yokugcina i-repository xa udala i-backups epheleleyo iyafana, i-16 GB, kwimeko yeekopi ezikhulayo - i-14 GB ngokubaleka, oku kuthetha ukuchithwa kokusebenza.
Uphononongo lwe-AMANDA
Ngesicelo somthathi-nxaxheba yongeza iimvavanyo ze-AMANDA,
Iziphumo zovavanyo oluqhutywa nge tar njengovimba kunye nocinezelo luvuliwe ngolu hlobo lulandelayo:

Inkqubo ilayisha ngokupheleleyo i-core core processor, kodwa ngenxa yediski ye-IOPS elinganiselweyo kwicala leseva yokugcina i-backup, ayikwazi ukufikelela kwisantya esiphezulu sokudlulisa idatha. Ngokubanzi, ukuseta kwakunzima ngakumbi kunabanye abathathi-nxaxheba, ekubeni umbhali weprogram akasebenzisi i-ssh njengothutho, kodwa uphumeza isikimu esifanayo kunye nezitshixo, ukudala nokugcina i-CA epheleleyo. Kuyenzeka ukunqanda ngokubanzi umxhasi kunye nomncedisi ogcinayo: umzekelo, ukuba abanakuthembana ngokupheleleyo, ngoko unako, njengokhetho, ukuthintela umncedisi ekuqaliseni ukubuyisela ngokucwangcisa ixabiso lenguqu ehambelanayo ukuya ku-zero ifayile yesethingi. Kuyenzeka ukuba udibanise ujongano lwewebhu lolawulo, kodwa ngokubanzi inkqubo eqwalaselweyo inokuzenzekela ngokupheleleyo kusetyenziswa izikripthi ezincinci ze-bash (okanye i-SCM, umzekelo ofanelekileyo). Kukho inkqubo ethile engeyiyo encinci yokuseta ugcino, ekubonakala ukuba kungenxa yenkxaso yoluhlu olubanzi lwezixhobo ezahlukeneyo zokugcina idatha (ikhasethi ze-LTO, ii-hard drives, njl.). Kuyafaneleka ukuba uqaphele ukuba kuzo zonke iinkqubo ezixutyushwa kweli nqaku, i-AMANDA yiyona kuphela ekwazile ukufumana ukutshintshwa kwegama. Ubungakanani bogcino lwendawo enye yayiyi-13 GB.
