Umsebenzi wasekhaya we backup Kubalulekile ukukhusela ulwazi esinalo kwiikhompyuter zethu, nangona kucacile ukuba yinto enye ukuyenza ekhaya kwaye enye into yokukhusela idatha yeyunivesithi okanye yenkampani, apho umthamo wolwazi uninzi. ezinkulu kwaye kukho uxanduva olwahlukeneyo. Ngoko ke, isidingo sokuba nezixhobo ezinamandla kunye neziguquguqukayo zikhulu kakhulu, nangona kucacile ukuba ezi nazo zinokusetyenziswa nguye nabani na wethu ekhaya.
Ngoku makhe sibone indlela yokufaka kunye nokuqwalasela i-rsnapshot yee-backups ezongeziweyo, sisixhobo esingasivumeli nje kuphela ukuba sikhusele ulwazi ngokukhuselekileyo nangokulula kodwa sikwenza oko ngokufanelekileyo kakhulu. Umzekelo wento esiyithethayo kukuba i indawo efunekayo yokugcina, kungakhathaliseki ukuba sisebenzisa kangakanani na, kunjalo phezulu kancinci kunogcino ukusukela ngoko inye kuphela into egciniweyo lukhuphelo lwezo fayile zilungisiweyo. Enye inzuzo ye-rsnapshot kukuba ii-backups zizikhonkco ezinzima kwii-backups zangaphambili, okoko nje bekungekho lutshintsho kwii-backups. zi cwangciso Kanjalo.
Ukuze ukwazi ukusebenzisa ngqube Kufuneka sihlangabezane nemiba ethile, kwaye oko kukuba sisixhobo esixhomekeke kwabanye ekusebenzeni kwaso. Umzekelo, makhe idinga i-rsync efakiweyo kwaye unofikelelo nge-SSH kwikhompyuter apho siza kugcina ii-backups zethu, oko kukuthi, kufuneka sizifakile SSH kuzo zombini iikhompyutha kunye nezitshixo ziqwalaselwe ukuba zikwazi ukufikelela ngaphandle kokungena igama eliyimfihlo 'ngesandla'.
Ke, kuqala kuzo zonke makhe siqwalasele oku:
I-ssh-keygen -t rsa
Apha i-SSH iza kusibuza eli binzana, kodwa njengoko siza kuphumeza imiyalelo ukude sifuna usebenziswano 0 ngoko ke siza kuyichitha le nto ngokucinezela iqhosha elithi Faka amaxesha ama-2 siyalelwa. Ekugqibeleni siza kuba neefayile ezi-2 ezintsha kwi ~/.ssh: enye yi-id_rsa kwaye iqulethe isitshixo sesazisi sabucala, esinye sithi id_rsa.pub kwaye iqulethe isitshixo soluntu. Sikhuphela le yokugqibela kwiseva ekude sisebenzisa i-ssh-copy-id yomyalelo, esicela igama eligqithisiweyo leakhawunti kwiseva exeliweyo kwaye emva koko ikhathalele ukulayisha nokuyigcina ngendlela eyiyo, oko kukuthi, ukwenza abalawuli abahambelanayo. kunye nokuseka iimvume eziyimfuneko:
# ssh-copy-id -i ~/.ssh/id_rsa.pub user@remoteserver
Emva koko sifaka i-rsync kunye ne-rsnapshot:
# sudo apt-fumana ukufaka i-rsync rsnapshot
Ngoku sihlela ifayile yoqwalaselo lwe-rsnapshot ukuseka ulawulo apho siza kwenza khona ii-backups:
# nano /etc/rsnapshot.conf
Silungisa icandelo le-snapshot_root ukubonisa apho siya kugcina khona ii-backups kwikhompyuter ekude:
# i-snapshot_root /disk1/backup
Siseka isithuba apho ngqube Iyakwenza umsebenzi wayo (kulo mzekelo, amaxesha amane ngosuku, oko kukuthi, rhoqo ngeyure ezintandathu), kwaye ukwenza oku sisusa i- # phambi kwaleyo siza kuyisebenzisa, kwaye siyiguqule njengoko sifuna, umzekelo. :
ikhefu ngeyure 4
Ngoku siseka iifolda zasekhaya esiza kuzilungelelanisa, apho sizongezela ecaleni kwendlela 'yogcino':
i-backup / ikhaya / i-localhost/
backup / etc localhost/
Kufuneka kuqatshelwe ukuba imihlaba yahlulwe 'ziithebhu', oku kuthetha ukuba emva kokungena enye sicinezela iqhosha lethebhu, njalo njalo. Kwakhona Singabonisa ukuba zeziphi iifayile esifuna ukuzikhupha kwii-backups zethu, apho sisebenzisa umgca onikezelwe kuye ngamnye kubo:
ngaphandle_ifayile /etc/rsnapshot.conf
ngaphandle_ifayile /etc/bashrc.conf
Emva koko sigcina kwaye sigqibezele olu lungelelwaniso, kodwa ngethamsanqa sinethuba lokuyijonga sisebenzisa iparamitha:
# rnapshot configtest
Ukuba yonke into ihamba kakuhle siya kufumana umyalezo othi 'I-Syntax Kulungile'.
Enye inketho kukuyiqhuba kwimo yovavanyo, esingena kuyo:
# rsnapshot -t ngeyure
Ekugqibeleni, sishiywe nje sebenzisa umfanekiso, esiyenzayo ngokuncamathisela indlela yokuphumeza, ekufuneka ihambelane nesithuba esisisebenzisileyo: ngeyure, yonke imihla, ngeveki okanye ngenyanga.
Kwimeko yethu:
# rsnapshot ngeyure
Siza kubona oko ngaphakathi /disk1/ugcino amaxwebhu ayakuba /daily.0/localhost/home y yonke imihla.0/localhost/etc, kwaye ngaphakathi kuzo kuya kuba yimixholo efanayo njengakwiifolda zekhompyuter ebesifuna ukuzikhusela. Kuphelele apho, kwaye ndiyabulela ngqube Ukususela ngoku sinokuthembela phambili i-backups ezongeziweyo kwinkqubo yethu.
