Umsebenzi wesikole we Isipele Kubalulekile ukuvikela imininingwane esinayo kumakhompiyutha ethu, yize kusobala ukuthi into eyodwa ukukwenza ekhaya okunye futhi okunye ukuthi kufanele uvikele imininingwane yeyunivesithi noma yenkampani, lapho umthamo wolwazi ungakanani enkulu futhi kunezibopho ezahlukahlukene. Ngalesi sizathu, isidingo samathuluzi anamandla futhi enza izinto ezihlukahlukene sikhulu kakhulu, yize kusobala ukuthi lawa angasetshenziswa yinoma ngubani ekhaya.
Manje ake sibone ungayifaka kanjani futhi uyilungiselele kanjani i-rsnapshot yama-backups akhuphukayo, iyithuluzi elingasivumeli nje kuphela ukuba sivikele ukwaziswa ngendlela ephephile nelula kodwa futhi eliyenza ngokuyimpumelelo. Isibonelo salokhu esikushoyo iqiniso lokuthi i- isikhala esidingekayo sokugcina, noma ngabe siyisebenzisa kanjani, kunjalo iphakeme kancane kune-backup kusukela lapho ukuphela kwento egcinwe yikhophi yalawo mafayela aguquliwe. Enye inzuzo ye-rsnapshot ukuthi izipele ziyizixhumanisi ezinzima kuma-backups wangaphambilini, lokhu inqobo nje uma kungabikho zinguquko ku Ukusekela ngokulondoloza Kunjalo.
Ukuze ukwazi ukusebenzisa i-rsnapshot kufanele sihlangane nezinkinga ezithile, futhi ukuthi kuyithuluzi elithembela kwabanye ukuthi lisebenze. Isibonelo, ake need rsync ifakiwe futhi inokufinyelela nge-SSH kwikhompyutha esizogcina kuyo izipele zethu, okusho ukuthi, kufanele ukuthi siyifakile ssh kuwo womabili amadivayisi futhi ngamisa okhiye ukuze bakwazi ukufinyelela ngaphandle kokufaka iphasiwedi 'ngesandla'.
Ngakho-ke, okokuqala nje sizokulungisa lokhu:
ssh-keygen -t rsa
Lapha i-SSH izosicela ibinzana, kepha njengoba sizokwenza imiyalo ukude sifuna ukusebenzisana okungu-0 ngakho-ke sizokulahla lokhu ngokucindezela ukhiye we-Enter / Enter izikhathi ezi-2 esizicelile. Ekugcineni sizoba namafayela amasha ama-2 ku- ~ / .ssh: one is id_rsa and contains the key identification key, the other is id_rsa.pub and contains the ukhiye womphakathi. Sikopisha okokugcina kuseva ekude sisebenzisa umyalo we-ssh-copy-id, osicela iphasiwedi ye-akhawunti kwiseva eshiwo bese sinakekela ukuyilayisha nokuyigcina ngendlela efanele, okusho ukuthi, ukudala izinkomba ezihambisanayo nokubeka izimvume ezidingekayo:
# ssh-copy-id -i ~ / .ssh / id_rsa.pub user @ iseva eyihlane
Khona-ke sifaka i-rsync ne-rsnapshot:
# sudo apt-get ukufaka rsync rsnapshot
Manje sihlela ifayili lokumiswa kwe-rsnapshot ukusungula umkhombandlela esizokwenza kuwo izipele:
# nano /etc/rsnapshot.conf
Siguqula isigaba se-snapshot_root ukuze sibonise lapho sizogcina khona izipele kukhompyutha ekude:
# snapshot_root / disk1 / backup
Sakha isikhawu lapho i-rsnapshot izokwenza umsebenzi wayo (kulesi sibonelo, kane ngosuku okungamahora ayisithupha wonke), futhi kulokhu sisusa i- # ephambi kwaleyo esizoyisebenzisa, futhi siyishintshe ukunambitha, ngokwesibonelo:
isikhashana i-4 yehora
Manje sakha amafolda endawo esizowavumelanisa, esiwafaka ndawonye nenketho ethi 'isipele':
isipele / ikhaya / i-localhost /
isipele / njll localhost /
Kumele kuqashelwe ukuthi izinkambu zihlukaniswe 'ngamathebhu', okusho ukuthi ngemuva kokufaka eyodwa sicindezela ukhiye wethebhu, njalo njalo. Kanjalo singakhombisa ukuthi yimaphi amafayela esifuna ukuwakhipha kuzipele zethu, lapho sisebenzisa khona umugqa onikezelwe ngamunye wabo:
khipha i-_file /etc/rsnapshot.conf
khipha i-_file /etc/bashrc.conf
Ngemuva kwalokho silondoloza futhi siqede lokhu kumiswa, kodwa ngenhlanhla sinethuba lokukuhlola ngokusebenzisa ipharamitha:
# rnapshot ukumisa
Uma konke kuhamba kahle sizothola umyalezo othi 'Sintax KULUNGILE'.
Enye inketho ukuyisebenzisa ngemodi yokuhlola, esiyifaka kuyo:
# rsnapshot -t ngehora
Ekugcineni, simane nje sinakho sebenzisa i-rsnapshot, esikwenza ngokunamathisela imodi yokwenza, okumele ifane nesikhathi esisisebenzisile: ngehora, nsuku zonke, masonto onke noma ngenyanga.
Esimweni sethu:
#rsnapshot njalo ngehora
Sizokubona lokho ngaphakathi / disk1 / isipele amafolda azoba / nsuku zonke.0/localhost/home y nsuku zonke.0 / localhost / njll, futhi ngaphakathi kwazo kuzoba nokuqukethwe okufanayo nakumafolda eqembu ebesifuna ukuwavikela. Yilokho kuphela, futhi ngiyabonga i-rsnapshot kusukela manje kuqhubeke singathembela izipele ezikhulayo ohlelweni lwethu.
