Kutsigira michina chaiyo ndiyo imwe yenzvimbo dzinoda kupihwa kutariswa zvakanyanya kana uchikwenenzvera mutengo wekambani. Isu tinokuudza kuti iwe unogona sei kumisikidza backups mugore uye chengetedza bhajeti yako.
Databases chinhu chakakosha chekushandisa kune chero kambani. Ichi ndicho chikonzero nei michina chaiyo yave kudiwa. Vashandisi vanogona kushanda munzvimbo chaiyo inopa dziviriro kubva pakubatwa kwedata remuviri uye kuburitswa kweruzivo rwakavanzika.
Mazhinji makambani makuru uye epakati nepakati anovimba nemaVM neimwe nzira. Vanochengeta huwandu hukuru hweruzivo rwakakosha. Ndicho chikonzero nei zvakakosha kutarisira kugadzira zvinyorwa kuitira kuti rimwe zuva "oops" rirege kuitika uye dhatabhesi iyo yakazadzikiswa kwemakore kamwe kamwe inoshanduka kuva yakakuvadzwa kana isingasviki.
Kazhinji, makambani anogadzira makopi ekuchengetedza eVM avo uye anoachengeta munzvimbo dzakasiyana dzedata. Uye kana kamwe-kamwe nzvimbo yekutanga yekugadzira ruzivo ikangoerekana yatadza, unogona kukurumidza kupora kubva kune backup. Izvo zvakanaka kana iyo backup ichichengetwa munzvimbo dzakasiyana dzedata, sezvazvinoita . Nekudaro, vazhinji vanopa havagone kupa sevhisi yakadai kana kukumbira imwe mari pairi. Nekuda kweizvozvo, kuchengetedza ma backups kunodhura peni rakanaka.
Nekudaro, kushandisa zvine hungwaru kugona kwegore kunogona kuderedza mutoro wemari.
Sei gore?
VM backups inochengetwa zviri nyore pamapuratifomu emakore. Pane zvakawanda zvinogadzirisa pamusika izvo zvinorerutsa maitiro ekutsigira uye kudzoreredza chaiwo michina. Nerubatsiro rwavo, unogona kuronga kudzoreredzwa kwedata kusingapindiki kubva kumashini chaiwo uye kuve nechokwadi chesevhisi yakagadzikana yezvishandiso zvinoenderana neiyi data.
Maitiro ekuchengetedza anogona kuve otomatiki zvichienderana nekuti ndeapi mafaera uye kangani iyo data inoda kutsigirwa. "Gore" harina chero miganhu yakaoma. Kambani inogona kusarudza mashandiro uye mashandiro anoenderana nezvido zvebhizinesi ravo uye kubhadhara chete zviwanikwa zvavanoshandisa.
Zvivakwa zvemuno hazvina kugona uku. Iwe unofanirwa kubhadhara midziyo yese kamwechete (kunyangwe midziyo isina basa), uye kana paine kudikanwa kwekuwedzera kubereka, iwe unofanirwa kutenga mamwe maseva, izvo zvinotungamira kukuwedzera mari. Cloud4Y inopa nzira ina dzekudzikisa mari yako yekuchengetedza database.
Saka ungachengetedza sei mari?
Kuwedzera kopi
Iyo kambani inofanirwa kugara ichitsigira data yakakosha. Asi iyi data inowedzera muhuwandu nekufamba kwenguva. Nekuda kweizvozvo, imwe neimwe inotevera backup inotora yakawanda uye yakawanda nzvimbo uye inoda nguva yakawanda yekuisa mudura. Iwe unogona kurerutsa maitiro nekuchengetedza ekuwedzera backups.
Iyo yekuwedzera nzira inotora kuti iwe unoita backup kamwe chete kana pane dzimwe nguva (zvinoenderana negadziriro yako yekuchengetedza). Imwe neimwe inotevera backup ine chete shanduko dzakaitwa kune yekutanga backup. Nekuti mabhekisheni anoitika zvishoma uye shanduko nyowani chete dzinotsigirwa, masangano haafanire kubhadharira hombe yegore data kutamiswa.
Deredza kuchinjanisa mafaira kana zvikamu
Dzimwe nguva RAM yemuchina chaiwo inogona kunge isina kukwana kuchengetedza maapplication uye OS data. Mune ino kesi, iyo OS inotora imwe chikamu cheiyo hard drive kuchengetedza imwe data. Iyi data inodaidzwa kuti peji faira kana swap partition muWindows neLinux zvakateerana.
Kazhinji, mafaira emapeji ane 1,5 nguva yakakura kupfuura RAM. Iyo data iri mumafaira aya inochinja nguva nenguva. Uye pese panoitwa backup, mafaera aya anotsigirwawo. Saka zvingava nani kusabvisa aya mafaera kubva kubhaubheri. Ivo vanozotora yakawandisa nzvimbo mugore, sezvo sisitimu ichivachengetedza neyega yega backup (mafaira ari kugara achichinja!).
Kazhinji, pfungwa ndeyekudzosera chete iyo data iyo kambani inoda chaizvo. Uye izvo zvisina kufanira, senge paging faira, hazvifanirwe kutsigirwa.
Kudzokorora uye kuchengetedza backups
Virtual muchina backups inorema yakawanda, saka iwe unofanirwa kuchengetedza yakawanda nzvimbo mugore. Naizvozvo, iwe unogona kuchengetedza mari nekudzikisa saizi ye backups dzako. Apa ndipo panogona kubatsira kudzokorora. Iyi ndiyo nzira yekukopa chete zvidhinha zvakashandurwa zve data uye kutsiva makopi ezvivharo zvisina kuchinjika nereferensi kumabhuroko ekutanga. Iwe unogona zvakare kushandisa akasiyana dura kudzvanya iyo yekupedzisira backup kuchengetedza yakanyanya ndangariro.
Ichi chinyorwa chinonyanya kukosha kana iwe uchitevera mutemo we 3-2-1 kana zvasvika pakuchengeta ma backups. Mutemo unoti kuti uve nechokwadi chekuchengetwa kwedata kwakavimbika, unofanirwa kunge uine makopi MATATU ekuchengetera akachengetwa muMAVIRI akasiyana mafomati ekuchengetera, aine IMWE yemakopi akachengetwa kunze kwekuchengetera kukuru.
Iyi musimboti wekuona kukanganisa kushivirira inotora yakawandisa data chengetedzo, saka kudzikisa iyo backup vhoriyamu kungave kwakakosha.
GFS (Sekuru-Baba-Mwanakomana) mutemo wekuchengetedza
Maitiro ekugadzira uye kuchengetedza ma backups akarongwa mumakambani mazhinji? Asi hapana nzira! Masangano anogadzira ma backups uye... kanganwa nezvawo. Kwemwedzi, kana kunyange makore. Izvi zvinoguma nemitengo isingakoshi yedata risingambo shandiswe. Nzira yakanaka yekutarisana neizvi ndeyekushandisa mitemo yekuchengetedza. Aya marongero anosarudza kuti mangani ma backups anogona kuchengetwa mugore panguva imwe chete.
Iyo yakapfava yekuchengetera mutemo inotsanangurwa neiyo "yekutanga mukati, yekutanga kubuda". Nepolicy iyi, imwe nhamba yema backups inochengetwa, uye kana muganho wasvika, yekare inobviswa kuti iwane nzvimbo yeitsva. Asi zano iri harina kunyatsoshanda, kunyanya kana iwe uchida kupa huwandu hwekudzoreredza mapoinzi mudiki diki rekuchengetedza. Mukuwedzera, kune mitemo yepamutemo uye yekambani inoda kuchengetedza data kwenguva refu.
Dambudziko iri rinogona kugadziriswa nekushandisa mutemo weGFS (Sekuru-Baba-Mwanakomana). "Mwanakomana" ndiyo inonyanya kushandiswa kuchengetedza. Somuenzaniso, zuva nezuva. Uye "sekuru" chinhu chisingawanzoitiki, semuenzaniso, pamwedzi. Uye pese painogadzirwa backup yemazuva ese, inova mwanakomana wevhiki rapfuura backup yevhiki. Iyi modhi inopa iyo kambani mamwe mapoinzi ekudzoreredza ane imwechete yakaderera nzvimbo yekuchengetera.
Kana iwe uchida kuchengetedza ruzivo kwenguva yakareba, kune yakawanda, asi haina kumbobvira yakakumbirwa, unogona kushandisa iyo inonzi ice inotonhorera yekuchengetedza. Mutengo wekuchengetedza data ipapo wakaderera, asi kana kambani ikakumbira iyi data, uchafanirwa kubhadhara. Zvakafanana newadhiropu yerima iri kure. Pane zvinhu zvakawanda mairi izvo zvichange zvisina chinhu mumakore 10-20-50. Asi paunosvika kune imwe chete, iwe uchapedza nguva yakawanda. Cloud4Y yakadana iyi chengetedzo "".
mhedziso
Backup chinhu chakakosha chekuchengetedza kune chero bhizinesi. Kuchengetedza ma backups mugore kuri nyore kwazvo, asi dzimwe nguva sevhisi inodhura zvakanyanya. Uchishandisa nzira dzatakanyora, unogona kuderedza mari yekambani yako pamwedzi.
