Qhov tsab xov xwm no yuav piv cov cuab yeej thaub qab, tab sis ua ntej koj yuav tsum paub sai thiab zoo npaum li cas lawv tiv nrog cov ntaub ntawv rov qab los ntawm kev thaub qab.
Txhawm rau kom yooj yim ntawm kev sib piv, peb yuav txiav txim siab rov qab los ntawm kev thaub qab tag nrho, tshwj xeeb tshaj yog vim txhua tus neeg sib tw txhawb hom kev ua haujlwm no. Rau kev yooj yim, cov lej twb tau nruab nrab (tus lej lej ntawm ntau qhov kev khiav). Cov txiaj ntsig yuav raug muab sau tseg rau hauv ib lub rooj, uas tseem yuav muaj cov ntaub ntawv hais txog lub peev xwm: muaj lub vev xaib sib txuas, yooj yim ntawm kev teeb tsa thiab kev ua haujlwm, muaj peev xwm automate, muaj ntau yam ntxiv (piv txwv li, tshawb xyuas cov ntaub ntawv ncaj ncees) , lwm. Cov graphs yuav qhia cov load ntawm tus neeg rau zaub mov qhov twg cov ntaub ntawv yuav raug siv (tsis yog lub server rau khaws cov ntaub ntawv thaub qab).
Cov ntaub ntawv rov qab
rsync thiab tar yuav siv los ua qhov taw qhia siv txij li thaum yooj yim scripts rau ua backup luam.
Rsync coped nrog cov ntaub ntawv xeem teev nyob rau hauv 4 feeb thiab 28 vib nas this, qhia
xws li load
Cov txheej txheem rov qab tau tsoo ib qho kev txwv ntawm disk subsystem ntawm cov ntaub ntawv khaws cia (sawtooth graphs). Koj tseem tuaj yeem pom meej qhov chaw thau khoom ntawm ib lub ntsiav yam tsis muaj teeb meem (tsawg iowait thiab softirq - tsis muaj teeb meem nrog lub disk thiab network, feem). Txij li thaum lwm ob qhov kev pab cuam, xws li rdiff-backup thiab rsnapshot, yog raws li rsync thiab tseem muab rsync li niaj zaus rov qab, lawv yuav muaj kwv yees li tib lub sijhawm thauj khoom thiab lub sijhawm rov qab.
Tar tau ua sai dua me ntsis
2 feeb thiab 43 feeb:
Tag nrho cov kab ke thauj khoom tau siab dua ntawm qhov nruab nrab los ntawm 20% vim qhov nce softirq - cov nqi nyiaj siv ua haujlwm thaum lub sijhawm ua haujlwm ntawm lub network subsystem tau nce.
Yog hais tias lub archive yog ntxiv compressed, lub sij hawm rov qab mus rau 3 feeb 19 vib nas this.
nrog xws li ib tug load ntawm lub ntsiab server (unpacking ntawm sab ntawm lub ntsiab server):
Cov txheej txheem decompression yuav siv sij hawm ob lub processor cores vim tias muaj ob txheej txheem khiav. Feem ntau, qhov no yog qhov kev xav tau. Tsis tas li ntawd, qhov txiaj ntsig sib piv (3 feeb thiab 20 vib nas this) tau txais thaum khiav gzip ntawm lub server sab nrog thaub qab; cov ntaub ntawv thauj khoom ntawm lub server tseem ceeb heev zoo ib yam li khiav tar yam tsis muaj gzip compressor (saib daim duab dhau los).
Π rdiff- thaub qab koj tuaj yeem synchronize qhov thaub qab kawg uas koj tau ua siv rsync li niaj zaus (cov txiaj ntsig yuav zoo sib xws), tab sis cov thaub qab qub tseem yuav tsum tau rov qab los siv rdiff-backup program, uas ua tiav qhov kev kho dua tshiab hauv 17 feeb thiab 17 vib nas this, qhia.
qhov no load:
Tej zaum qhov no tau npaj, yam tsawg kawg kom txwv qhov ceev ntawm cov neeg sau ntawv . Cov txheej txheem ntawm kev rov ua kom rov qab tau daim ntawv theej nws tus kheej yuav siv sij hawm tsawg dua ib nrab ntawm ib qho tseem ceeb, nrog kev ua tau zoo sib xws (piv txwv li 2-5 zaug qeeb) dhau disk thiab network nrog rsync.
Rsnapshot Rau kev rov qab los, nws qhia tias siv rsync li niaj zaus, yog li nws cov txiaj ntsig yuav zoo sib xws. Feem ntau, qhov no yog li cas nws tig tawm.
Ua faus Kuv ua tiav txoj hauj lwm ntawm kev rov ua kom thaub qab hauv 7 feeb thiab 2 vib nas this nrog
nrog rau qhov load:
Nws ua haujlwm sai heev, thiab tsawg kawg yog yooj yim dua li cov ntshiab rsync: koj tsis tas yuav nco ntsoov cov chij, ib qho yooj yim thiab intuitive cli interface, built-in txhawb rau ntau daim ntawv luam - txawm hais tias nws yog ob zaug qeeb. Yog tias koj xav tau rov qab cov ntaub ntawv los ntawm qhov kawg thaub qab koj tau ua, koj tuaj yeem siv rsync, nrog rau ob peb qhov lus ceeb toom.
Qhov kev zov me nyuam tau pom kwv yees li tib qhov ceev thiab thauj khoom Thaub laus thaum ua kom rsync hloov hom, xa cov thaub qab rau
7 feeb thiab 42 feeb:
Tab sis nyob rau hauv cov ntaub ntawv hloov tsheb hom, BackupPC coped nrog tar ntau maj mam: nyob rau hauv 12 feeb thiab 15 vib nas this, lub processor load feem ntau qis dua.
ib thiab ib nrab sijhawm:
Qhov du tsis muaj encryption pom tau zoo dua me ntsis, rov ua kom rov qab tau hauv 10 feeb thiab 58 vib nas this. Yog tias koj qhib encryption siv gpg, lub sijhawm rov qab yuav nce mus rau 15 feeb thiab 3 vib nas this. Tsis tas li ntawd, thaum tsim ib lub chaw khaws cia rau khaws cov ntawv theej, koj tuaj yeem hais qhia qhov loj me uas yuav siv tau thaum faib cov ntaub ntawv nkag. Nyob rau hauv dav dav, ntawm cov pa nyuaj drives, kuj vim hais tias ntawm ib leeg-threaded kev khiav hauj lwm hom, tsis muaj ntau qhov sib txawv. Nws yuav tshwm sim ntawm qhov sib txawv ntawm qhov sib txawv thaum siv hybrid cia. Lub load ntawm lub server tseem ceeb thaum rov qab los yog raws li hauv qab no:
tsis muaj encryption

Lub sijhawm ua haujlwm 14 feeb
AES encryption, lzo compression
Lub sijhawm ua haujlwm 6 feeb, 19 vib nas this
Zuag qhia tag nrho, tsis phem. Nws tag nrho yog nyob ntawm qhov ceev ntawm lub processor ntawm lub backup server, uas tuaj yeem pom meej los ntawm lub sijhawm khiav ntawm qhov kev pab cuam nrog cov compressors sib txawv. Nyob rau sab nraud neeg rau zaub mov, ib txwm tar tau pib, yog li yog tias koj piv nrog nws, qhov rov qab yog 3 zaug qeeb. Tej zaum nws yuav tsim nyog kuaj xyuas cov haujlwm hauv ntau txoj xov, nrog ntau tshaj ob txoj xov.
BorgBackup nyob rau hauv unencrypted hom nws yog me ntsis qeeb dua tar, nyob rau hauv 2 feeb 45 vib nas this, txawm li cas los, tsis zoo li tar, nws tau los ua deduplicate lub repository. Lub load tig tawm los ua
cov hauv qab no:
Yog tias koj ua kom blake-raws li encryption, qhov thaub qab rov qab nrawm dua me ntsis. Lub sij hawm rov qab nyob rau hauv hom no yog 3 feeb 19 vib nas this, thiab lub load ploj mus
zoo li no:
AES encryption qeeb qeeb me ntsis, lub sijhawm rov qab yog 3 feeb 23 vib nas this, qhov thauj khoom tshwj xeeb
tsis tau hloov:
Txij li thaum Borg tuaj yeem ua haujlwm nyob rau hauv ntau txoj xov xov, lub processor load yog qhov siab tshaj plaws, thiab thaum ua haujlwm ntxiv, lub sijhawm ua haujlwm tsuas yog nce. Thaj, nws tsim nyog tshawb nrhiav multithreading zoo ib yam li zbackup.
Rawg coped nrog qhov rov qab me ntsis qeeb dua, lub sijhawm ua haujlwm yog 4 feeb 28 vib nas this. Lub load zoo li
zoo li no:
Pom tau tias cov txheej txheem rov qab ua haujlwm hauv ntau txoj xov, tab sis qhov ua tau zoo tsis yog siab npaum li BorgBackup, tab sis piv rau lub sijhawm rau rsync li niaj zaus.
Nrog kev pab los ntawm Kev ceev Nws tuaj yeem rov qab tau cov ntaub ntawv hauv 8 feeb thiab 19 vib nas this, lub load yog
xws li:
Lub load tseem tsis siab heev, txawm tias qis dua li ntawm tar. Hauv qee qhov chaw muaj qhov tawg, tab sis tsis muaj ntau tshaj qhov load ntawm ib qho tseem ceeb.
Kev xaiv thiab kev ncaj ncees ntawm cov txheej txheem rau kev sib piv
Raws li tau hais nyob rau hauv ib qho ntawm cov kab lus dhau los, cov txheej txheem thaub qab yuav tsum ua raws li cov hauv qab no:
- Yooj yim ntawm kev siv
- Versatility
- Kev ruaj khov
- Ceev ceev
Nws yog tsim nyog xav txog txhua lub ntsiab lus sib cais hauv kev nthuav dav ntxiv.
Kev ua haujlwm yooj yim
Nws yog qhov zoo tshaj plaws thaum muaj ib lub pob "Ua txhua yam kom zoo," tab sis yog tias koj rov qab mus rau cov kev pab cuam tiag tiag, qhov yooj yim tshaj plaws yuav yog qee qhov kev paub thiab cov qauv kev ua haujlwm.
Cov neeg siv feem ntau yuav zoo dua yog tias lawv tsis tas yuav tsum nco ntsoov ntau pawg ntawm cov yuam sij rau cli, teeb tsa ntau pawg sib txawv, feem ntau tsis pom kev xaiv ntawm lub vev xaib lossis tui, lossis teeb tsa cov ntawv ceeb toom txog kev ua haujlwm tsis tiav. Qhov no kuj suav nrog kev muaj peev xwm yooj yim "haum" cov kev daws teeb meem thaub qab rau hauv cov txheej txheem uas twb muaj lawm, nrog rau kev ua haujlwm ntawm cov txheej txheem thaub qab. Kuj tseem muaj peev xwm ntawm kev teeb tsa siv tus thawj tswj pob, lossis hauv ib lossis ob lo lus txib xws li "download thiab unpack". curl ΡΡΡΠ»ΠΊΠ° | sudo bash - ib txoj kev nyuaj, txij li thaum koj yuav tsum tau xyuas dab tsi tuaj txog ntawm qhov txuas.
Piv txwv li, ntawm cov neeg sib tw tau txiav txim siab, ib qho kev daws teeb meem yooj yim yog burp, rdiff-backup thiab so, uas muaj cov yuam sij mnemonic rau ntau hom kev ua haujlwm. Me ntsis complex yog borg thiab duplicity. Qhov nyuaj tshaj plaws yog AMANDA. Tus so yog qhov chaw nyob nruab nrab ntawm qhov yooj yim ntawm kev siv. Txawm li cas los xij, yog tias koj xav tau ntau dua 30 vib nas this los nyeem cov neeg siv phau ntawv, lossis koj yuav tsum tau mus rau Google lossis lwm lub tshuab tshawb nrhiav, thiab tseem scroll los ntawm daim ntawv ntev ntawm kev pab, qhov kev txiav txim siab nyuaj, ib txoj kev lossis lwm qhov.
Qee tus neeg sib tw tau txiav txim siab tuaj yeem xa cov lus ntawm e-mailjabber, thaum lwm tus cia siab rau cov lus ceeb toom hauv qhov system. Tsis tas li ntawd, feem ntau cov kev daws teeb meem nyuaj tsis muaj teeb meem kev ceeb toom tag nrho. Txawm li cas los xij, yog tias qhov kev pabcuam thaub qab tsim tawm tsis yog xoom xa rov qab code, uas yuav raug nkag siab los ntawm qhov kev pabcuam rau lub sijhawm ua haujlwm (cov lus yuav raug xa mus rau tus thawj tswj hwm lossis ncaj qha rau kev saib xyuas) - qhov xwm txheej yooj yim. Tab sis yog tias cov txheej txheem thaub qab, uas tsis khiav ntawm lub server thaub qab, tsis tuaj yeem teeb tsa, txoj hauv kev pom tseeb hais txog qhov teeb meem yog qhov nyuaj dhau lawm. Txawm li cas los xij, tshaj tawm cov lus ceeb toom thiab lwm cov lus tsuas yog rau lub vev xaib interface lossis rau lub cav yog qhov kev coj ua tsis zoo, vim feem ntau lawv yuav tsis quav ntsej.
Raws li rau automation, ib qho kev pab cuam yooj yim tuaj yeem nyeem cov kev hloov pauv ib puag ncig uas teeb tsa nws txoj haujlwm ua haujlwm, lossis nws muaj qhov tsim kho cli uas tuaj yeem ua tiav tus cwj pwm thaum ua haujlwm hauv lub vev xaib, piv txwv li. Qhov no kuj suav nrog qhov muaj peev xwm ua haujlwm tsis tu ncua, muaj cov hauv kev nthuav dav, thiab lwm yam.
Versatility
Ib nrab echoing cov ntu ntu dhau los hais txog automation, nws yuav tsum tsis yog ib qho teeb meem tshwj xeeb kom "haum" cov txheej txheem thaub qab rau hauv cov txheej txheem uas twb muaj lawm.
Nws yog tsim nyog sau cia tias kev siv cov chaw nres nkoj tsis yog tus qauv (zoo, tshwj tsis yog lub vev xaib interface) rau kev ua haujlwm, kev siv cov encryption tsis yog tus qauv, kev sib pauv ntawm cov ntaub ntawv uas siv cov txheej txheem uas tsis yog tus qauv yog cov cim qhia tias tsis yog. - universal daws. Feem ntau, txhua tus neeg sib tw muaj lawv nyob rau hauv ib txoj kev los yog lwm qhov rau qhov pom tseeb vim li cas: simplicity thiab versatility feem ntau tsis mus ua ke. Raws li ib qho kev zam - burp, muaj lwm yam.
Raws li kev kos npe - muaj peev xwm ua haujlwm siv ssh tsis tu ncua.
Ua hauj lwm ceev
Qhov teeb meem feem ntau thiab tsis sib haum xeeb. Ntawm qhov tod tes, peb tau tsim cov txheej txheem, nws ua haujlwm sai li sai tau thiab tsis cuam tshuam nrog cov haujlwm tseem ceeb. Ntawm qhov tod tes, muaj surge hauv tsheb thiab processor load thaum lub sij hawm thaub qab. Nws tseem tsim nyog sau cia tias cov kev pabcuam ceev tshaj plaws rau kev luam ntawv feem ntau yog cov neeg pluag tshaj plaws ntawm cov haujlwm uas tseem ceeb rau cov neeg siv. Ntxiv dua thiab: yog tias yuav kom tau txais ib daim ntawv tsis muaj hmoo ntawm ob peb kaum ntawm bytes loj nrog tus password, thiab vim tias nws tag nrho cov nqi kev pabcuam (yog, yog, kuv nkag siab tias cov txheej txheem thaub qab feem ntau tsis txhob liam ntawm no), thiab koj yuav tsum tau rov nyeem dua txhua cov ntaub ntawv nyob rau hauv lub repository los yog nthuav tag nrho cov archive - lub backup system yeej tsis ceev. Lwm lub ntsiab lus uas feem ntau dhau los ua qhov tsis txaus ntseeg yog qhov ceev ntawm kev xa cov thaub qab los ntawm ib qho archive. Muaj qhov zoo dua ntawm no rau cov neeg uas tuaj yeem luam tawm lossis txav cov ntaub ntawv mus rau qhov chaw xav tau yam tsis muaj kev tswj hwm ntau (rsync, piv txwv li), tab sis feem ntau qhov teeb meem yuav tsum tau daws nyob rau hauv ib txoj hauv kev, empirically: los ntawm kev ntsuas lub sij hawm rov qab. thiab qhib qhia cov neeg siv txog qhov no.
Kev ruaj khov
Nws yuav tsum nkag siab txog txoj kev no: ntawm ib sab, nws yuav tsum muaj peev xwm xa cov ntaub ntawv thaub qab rov qab rau txhua txoj hauv kev, ntawm qhov tod tes, nws yuav tsum tiv taus ntau yam teeb meem: kev cuam tshuam hauv network, disk tsis ua haujlwm, tshem tawm ib feem ntawm cov khoom siv. chaw cia khoom.
