Lesi sibuyekezo siyaqhubeka , ebhalwe ngesicelo sabafundi, izokhuluma nge-UrBackup, BackupPC, kanye ne-AMANDA.
Isibuyekezo se-UrBackup.
Ngesicelo sombambi qhaza Ngengeza isibuyekezo se-UrBackup, uhlelo lwesipele lweseva yeklayenti. Ikuvumela ukuthi udale izipele ezigcwele nezikhuphukayo, ingasebenza nezifinyezo zedivayisi (Win kuphela?), futhi ingakha futhi izipele zamafayela. Iklayenti lingatholakala kunethiwekhi efanayo neseva, noma lixhumeke nge-inthanethi. Ukulandelela kokushintsha kumenyezelwe, okukuvumela ukuthi uthole ngokushesha umehluko phakathi kwamakhophi ayisipele. Kukhona futhi ukusekelwa kokudonswa kwedatha ye-server-side, okugcina isikhala. Uxhumano lwenethiwekhi lubethelwe, futhi kukhona futhi isixhumi esibonakalayo sewebhu sokuphatha iseva. Ake sibone ukuthi yini angayenza:
Kumodi yokulondoloza ephelele, imiphumela elandelayo itholakele:

Usayizi wekhosombe kuzo zombili izimo wawucishe ube ngu-14 GB, okubonisa ukuphindaphinda okusebenzayo ohlangothini lweseva. Kufanele futhi kuqashelwe ukuthi kunomehluko phakathi kwesikhathi sokudala ikhophi yasenqolobaneni kuseva neklayenti, okubonakala ngokucacile kumagrafu futhi kuyibhonasi emnandi kakhulu, njengoba isikhombimsebenzisi sewebhu sibonisa isikhathi sokusebenza kwenqubo yokusekelayo ohlangothini lweseva ngaphandle kokucabangela
isimo seklayenti. Ngokuvamile, amagrafu amakhophi agcwele nakhuphukayo awahlukaniseki. Umehluko kuphela mhlawumbe ukuthi iphathwa kanjani ohlangothini lweseva. Ngijabule futhi ngomthwalo ophansi weprosesa ohlelweni olungasasebenzi.
Ukubuyekezwa kwe-BackupPC
Ngesicelo sombambi qhaza Ngengeza isibuyekezo se-BackupPC. Le softhiwe ifakwe kuseva yokugcina ikhophi, ebhalwe nge-perl, futhi isebenza phezu kwamathuluzi ahlukahlukene okulondoloza - ngokuyinhloko i-rsync, i-tar. I-Ssh ne-smb zisetshenziswa njengezokuthutha; kukhona futhi isikhombimsebenzisi sewebhu esekwe ku-cgi (efakwe phezulu kwe-apache). I-interface yewebhu inohlu olubanzi lwezilungiselelo. Phakathi kwezici yikhono lokusetha isikhathi esincane phakathi kwama-backups, kanye nesikhathi lapho ama-backups angeke adalwe. Lapho ukhetha isistimu yefayela yeseva eyisipele, udinga ukuqinisekisa ukuthi izixhumanisi eziqinile ziyasekelwa. Ngakho, isistimu yefayela yokugcina ayikwazi ukuhlukaniswa ngamaphoyinti wokukhweza. Sekukonke, isipiliyoni esimnandi, ake sibone ukuthi le software ikwazi ukwenzani:
Kumodi yokudala izipele ezigcwele nge-rsync, kutholwe imiphumela elandelayo:

Kumodi yokulondoloza ekhuphukayo, bekufanele ngilahle itiyela ngoba izipele azizange zidalwe ngalezi zilungiselelo.
Imiphumela yokudala ama-backups akhuphukayo usebenzisa i-rsync yile:

Ngokuvamile, i-rsync inenzuzo encane yesivinini; Lokhu kungase kususwe ngokwengxenye ukusetshenziswa kwe-CPU encane nge-tar njengohlelo oluyisipele. Enye inzuzo ye-rsync ukuthi isebenza namakhophi akhuphukayo. Ubukhulu benqolobane lapho udala izipele ezigcwele ziyafana, i-16 GB, esimweni samakhophi akhuphukayo - i-14 GB ngokugijima ngakunye, okusho ukuphindaphinda kokusebenza.
Ukubuyekeza kwe-AMANDA
Ngesicelo sombambi qhaza ingeza izivivinyo ze-AMANDA,
Imiphumela yokuhlolwa okwenziwa nge-tar njengoba i-archiver nokucindezelwa kunikwe amandla imi kanje:

Uhlelo lulayisha ngokugcwele umongo wephrosesa owodwa, kodwa ngenxa yediski ye-IOPS enomkhawulo ohlangothini lweseva yokugcina ikhophi yasenqolobaneni, alukwazi ukuzuza isivinini sokudlulisa idatha. Ngokuvamile, ukusetha kube nzima kakhulu kunabanye ababambiqhaza, njengoba umbhali wohlelo engasebenzisi i-ssh njengendlela yokuthutha, kodwa usebenzisa uhlelo olufanayo olunokhiye, ukudala nokugcina i-CA egcwele. Kungenzeka ukukhawulela kabanzi iklayenti neseva eyisipele: isibonelo, uma bengakwazi ukwethembana ngokuphelele, ungakwazi, njengenketho, ukuvimbela iseva ukuthi iqalise ukubuyisela isipele ngokusetha inani lokuguquguquka okuhambisanayo kuya ku-zero ku-13. ifayela lezilungiselelo. Kungenzeka ukuxhuma isixhumi esibonakalayo sewebhu sokuphatha, kodwa ngokuvamile isistimu emisiwe ingenziwa ngokuzenzakalelayo kusetshenziswa imibhalo emincane ye-bash (noma i-SCM, isibonelo evumelekile). Kunohlelo oluthize olungeyona into encane lokusetha isitoreji, ngokusobala kungenxa yokusekelwa kohlu olubanzi lwamadivayisi ahlukahlukene okugcina idatha (amakhasethi e-LTO, ama-hard drive, njll.). Kuyaqapheleka futhi ukuthi kuzo zonke izinhlelo okuxoxwe ngazo kulesi sihloko, i-AMANDA iyona kuphela ekwazile ukuthola ukuqanjwa kabusha kohla lwemibhalo. Usayizi wenqolobane wokugijima okukodwa ubungu-XNUMX GB.
