Yemahara software ndiro musimboti webudiriro yemazuva ano uye nhaka yakajairika yevanhu vese. Mission - chengetedza iyi kodhi yezvizvarwa zvinotevera kuitira kuti nhoroondo yeLibhurari yeAlexandria isazombodzokororwa.
Kuti uite izvi, GitHub ichagadzira akawanda makopi ekuchengetedza pane akasiyana midhiya, kusanganisira yekugara kwenguva refu paSpitsbergen. Inowanikwa mune waimbova mugodhi wemarasha pakadzika 250 metres mupermafrost uye yakagadzirirwa hupenyu hwesherufu hwemakore angangoita 1000.
Mufananidzo wekodhi yesoftware yevanhu ichatorwa muna Kukadzi 2, 2020.
Iyo yenguva refu yekuchengetedza data chirongwa chakatangwa pamwe chete neLong Now Foundation, iyo Internet Archive, iyo Software Heritage Foundation, Arctic World Archive nevamwe vanobatika.

Kodhi yakakosha nhasi inogona kukanganwika kana kurasika nekufamba kwenguva. Chinhu chakaipisisa ndechekuti kana pakaitika njodzi yepasirese isu ticharasikirwa neruzivo rwese rwakanga rwakachengetwa pa "ephemeral" media: HDD, SSD, CD neDVD, yakagadzirirwa kwemakumi emakore anoverengeka, pamatepi ane mamiriro ehupenyu hwesevhisi yemakore makumi matatu anoda. kudzora zvakanyanya tembiricha uye mwando .
Mhinduro yedambudziko ndeyekudzokororwa kwemakopi ekuchengetedza, ndiko kuti, kuchengetedza software nemasangano akati wandei uye nenzira dzakasiyana. Chirongwa ichi chakadana zvatanga . Chirongwa chakapihwa muna Chivabvu 2019 -yekutanga prototype yesoftware yekugovera kuchengetedza data kwenguva yakareba nerutsigiro rwevazhinji vatori vechikamu uye ekunze kuchengetedza.
Vagadziri vehurongwa vanofungidzira kuti hardware inogona kusimba zvakanyanya kupfuura ephemeral media: saka, "kune huwandu hwenguva yemberi inogoneka umo kushanda kwemakomputa emazuva ano aripo, asi software yavo inonyanya kurasika."
GitHub inotiyeuchidza nezve akawanda akarasika matekinoroji angadai akabatsira: (resipi yake yakangowanikwazve muna 2014), , akarasika . Zviri nyore kufungidzira remangwana umo software yanhasi inoonekwa seyakajeka, yakakanganwa kwenguva refu isingakoshi, kusvika pakuda kusingatarisirwe kwayo kwamuka: "Senge chero backup, GitHub's archive chirongwa chakagadzirirwawo ramangwana risingatarisirwe," inodaro chirongwa cheGitHub. website Archive.
GitHub Archive
GitHub Archive inopa matatu mazinga ema backups:
- Kupisa: inenge nguva chaiyo
- Kudziya: inovandudzwa panguva dzakasiyana kubva pamwedzi kusvika pagore
- Cold: inovandudzwa ega ega 5+ makore
Mushure mekuita chero kwevashandisi veGitHub, data rese reGit rinodzokororwa kune akawanda data data kutenderera pasirese. Git backups, nyaya, zvikumbiro zvekudhonza, uye yese data yemushandisi paGitHub inochengetwa munzvimbo dzinoverengeka. Ruzivo urwu rwunowanikwa munguva chaiyo kuburikidza neGitHub API.
Pamusoro pezvo, inodzokorodza indexing inorongwa neGHTorrent crawler, iyo inozoisa zvinyorwa zuva nezuva kana pamwedzi. Kuburikidza neGH Archive, mifananidzo kubva mudura inogona kuwanikwa uchishandisa BigQuery mibvunzo. Mamwe makopi ekodhi akaiswa muInternet Archive inozivikanwa kwazvo Time Machine, inochengeta makopi munzvimbo dzakawanda. Chekupedzisira, iyo Software Heritage Foundation inogara ichikambaira GitHub uye kuwedzera veruzhinji marepositori kune yayo yekuchengetedza, iyo ine yeruzhinji API.
Arctic GitHub repository
Musi waFebruary 2, 2020, GitHub ichaita kopi yezvese zvinoshanda zveruzhinji repositori - uye woiisa muGitHub Arctic repository.
Iyo data ichachengetwa pa 3500-foot film reels inopiwa naPiql, kambani yeNorway iyo inonyanya kukoshesa kuchengetedza data kwenguva refu. Zvinoenderana nezviyero zveISO, iyi sirivheri halide polyester firimu ine hupenyu hwemakore mazana mashanu. Kutevedzera kuchembera bvunzo kwakaratidza kuti Piql firimu rinochengeta ruzivo kanenge kaviri kureba.
Pamusoro pezvo, GitHub Archive iri kushanda pamwe neMicrosoft Silica vaongorori vepurojekiti kupisa matura ese eruzhinji pamagirazi equartz egirazi vachishandisa femtosecond laser. Iyi svikiro ichave nechokwadi chekuchengetedza data kweanopfuura makore gumi,10.
Iyo Arctic GitHub kodhi repository yakagadzirwa pahwaro hweArctic World Archive (AWA) pakadzika 250 metres mupermafrost. Nzvimbo iyi iri mune waimbova mugodhi wemarasha paSpitsbergen archipelago, iyo isiri kure zvakanyanya kubva kuNorth Pole. Kudziya kwepasi rose kunongokanganisa mashoma emamita epermafrost uye hakutyisidzire mugodhi munguva pfupi iri kutevera (makore zviuru zvinoverengeka).
Svalbard inodzorwa senzvimbo isina mauto. Ndiyo imwe yenzvimbo dziri kure uye geopolitically yakagadzikana yekugara kwevanhu paPasi, maererano neGitHub. Pedyo neiyo inozivikanwa World Mbeu Vault, tariro huru yevanhu muchiitiko cheapocalypse.

AWA chirongwa chakabatana pakati pekambani yeNorwegian yehurumende yemigodhi Norske Spitsbergen Kulkompani (SNSK) uye mupi wekuchengetedza digital Piql AS. Nhoroondo uye tsika data kubva kuItari, Brazil, Norway, Vatican nedzimwe nyika dzakatochengetwa ipapo.

Reels yeGitHub kodhi ichachengetwa mumudziyo wesimbi-parutivi mukati mekamuri yakavharwa. Mufananidzo we02.02.2020 uchasanganisira ese anoshanda GitHub repositori uye chikamu chakakosha cheasina kushanda (tichitonga nenyeredzi, zvinoenderana, nezvimwewo), ese mabhinari mafaera anosvika zana KB. Imwe neimwe repository mune yakaparadzana tar faira. Zvese zvinofanirwa kukwana pa100 200 GB spools.
Pamwe chete neiyo archive pachava nekabhuku inoverengwa nevanhu uye zvinyorwa zvehunyanzvi paQR decoding, mafomu efaira, maencodings ehunhu uye mamwe mametadata akakosha kuitira kuti vazukuru vashandure data kudzoreredza kodhi.
Iyo dura ichasanganisirawo general Tech Tree gwara kana vaverengi vemangwana vapererwa nemakomputa ekushanda uye vachifanira kuvaka zvakare tekinoroji kubva kutanga.
