Yemahara software ndiro musimboti webudiriro yemazuva ano uye nhaka yakajairika yerudzi rwese. Mission GitHub Archive zvirongwa - kuchengetedza iyi kodhi yezvizvarwa zvinotevera, kuitira kuti nhoroondo yeLibhurari yeAlexandria isazombodzokororwa.

Kuti uite izvi, GitHub inochengetedza akawanda backups pane akasiyana midhiya, kusanganisira yekugara kwenguva refu. Arctic Code Vault paSvalbard. Inogara mune waichimbova mugodhi wemarasha pakadzika 250 metres mupermafrost uye yakagadzirirwa kugara kwemakore angangoita chiuru.

Mufananidzo wekodhi yesoftware yevanhu ichatorwa muna Kukadzi 2, 2020..

Chirongwa chekuchengetedza data kwenguva refu chakatangwa mukubatana neLong Now Foundation, Internet Archive, Software Heritage Foundation, Arctic World Archive, nevamwe vanobatika.

LOCKSS Project

Kodhi yanhasi yakakosha inogona kukanganwika kana kurasika nekufamba kwenguva. Mamiriro ezvinhu akaipisisa angave kana, kana pakaitika njodzi yenyika yose, takarasikirwa nemashoko ose akachengetwa pa "ephemeral" media: HDDs, SSDs, CDs, uye maDVD, akagadzirirwa kugara kwemakumi emakore, uye matepi, ane makore makumi matatu ehupenyu hunoda kusimba kwekushisa uye kudzora hunyoro.

Mhinduro kudambudziko iri kudzokorora kudzokorora, ndiko kuti, kuchengetedza software mumasangano akawanda uye nenzira dzakasiyana. Chirongwa ichi, chinonzi LOCKSS zvakatanga anenge makore makumi maviriChirongwa chakapihwa muna Chivabvu 2019. LOCKSS 2.0-alpha -yekutanga prototype yesoftware yakagoverwa yenguva refu yekuchengetedza data nerutsigiro rwevazhinji vatori vechikamu uye kunze kwekuchengetedza.

Vagadziri vehurongwa vanofungidzira kuti Hardware inogona kusimba zvakanyanya kupfuura ephemeral yekuchengetedza midhiya: 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: Kongiri yeRoma (resipi yaro yakawanikwa zvakare muna 2014), mushonga unodzivirira marariya DDFT, akarasika Saturn V roketi mifananidzoZviri nyore kufungidzira ramangwana iro software yanhasi inoonekwa seisina basa, yakakanganwika kwenguva refu kusvika pakuda kusingatarisirwe kwamuka: "Senge chero backup, GitHub's archive chirongwa chakagadzirirwa ramangwana risingatarisirwe," inodaro GitHub Archive chirongwa webhusaiti.

GitHub Archive

GitHub Archive inopa matatu mazinga ema backups:

• Kupisa: inenge munguva chaiyo
• Kudziya: inovandudzwa mwedzi wega wega kusvika pagore
• Cold: inogadziridzwa makore ese e5+

Mushure mekuita chero kweGitHub mushandisi, data rese reGit rinodzokororwa kune akawanda data nzvimbo kutenderera pasirese. Git backups, nyaya, zvikumbiro zvekudhonza, uye yese data yemushandisi paGitHub inochengetwa munzvimbo dzakawanda. Iyi ruzivo inowanikwa munguva chaiyo kuburikidza neGitHub API.

Pamusoro pezvo, kudzokorora indexing kwakarongwa neGHTorrent crawler, iyo inoshambadza zvinyorwa zuva nezuva kana pamwedzi. Snapshots kubva mudura inogona kutorwa kuburikidza neBigQuery mibvunzo kuburikidza neGH Archive. Mamwe makopi ekodhi anogarwa mune inozivikanwa Internet Archive "Time Machine," inochengeta makopi munzvimbo dzakawanda. Chekupedzisira, iyo Software Heritage Foundation inogara ichitarisa 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 inozviisa muGitHub Arctic Repository.

Iyo data ichachengetwa pa 3500-foot film reels inopiwa naPiql, kambani yeNorway inorapa kuchengetedza data kwenguva refu. Zvinoenderana ne ISO zviyero, iyi sirivheri halide polyester firimu ine hupenyu hwemakore mazana mashanu. Kutevedzera kuchembera bvunzo kwakaratidza kuti firimu rePiql rinochengeta ruzivo kweinenge kaviri kureba.

Pamusoro pezvo, GitHub Archive iri kushanda pamwe nevatsvagiri kubva kuMicrosoft Silica purojekiti kurekodha zvese zveruzhinji repositori pamagirazi equartz slabs vachishandisa femtosecond laser. Iyi svikiro yekuchengetedza ichachengetedza data kweanopfuura makore gumi.

Iyo Arctic GitHub kodhi repository iri kuvakwa paArctic World Archive (AWA) pakadzika 250 metres mupermafrost. Nzvimbo inochengeterwa zvinhu iri mune waimbova mugodhi wemarasha pazvitsuwa zveSvalbard, kusiri kure neNorth Pole. Kudziya kwepasi rose kuchakanganisa mamita mashoma epermafrost uye hakukonzeri njodzi yekumugodhi (zviuru zvemakore).

Spitsbergen inodzorwa chibvumirano chenyika dzakawanda senzvimbo isina mauto. Ndiyo imwe yenzvimbo dziri kure uye dzakagadzikana dzekugara kwevanhu paPasi, maererano neGitHub. Iyo yakakurumbira Global Mbeu Vault, tariro yakanakisa yevanhu muchiitiko cheapocalypse, inowanikwawo padyo.

Iyo Svalbard Global Seed Vault

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

Iyo GitHub kodhi reels ichachengetwa mumudziyo wakakomberedzwa nesimbi mukati mekamuri yakavharwa. Iyo Kukadzi 02.02.2020, 100, snapshot ichasanganisira ese anoshanda GitHub repositori uye chikamu chakakosha cheasingaite (zvichienderana nenyeredzi, zvinoenderana, nezvimwewo), ese emabhinari mafaera anosvika zana KB muhukuru. Imwe neimwe repository ichave mune yakaparadzana tar faira. Iyo yese reel inofanirwa kukwana pa200 120 GB reels.

Pamwe chete nearchive, kabhuku inoverengwa nevanhu uye zvinyorwa zvehunyanzvi paQR decoding, mafomati efaira, maencodings ehunhu, uye mamwe mametadata akakosha anozoverengerwa kuitira kuti zvizvarwa zvinotevera zvishandure data kudzoreredza kodhi yekutanga.

Iyo dura ichasanganisirawo general Tech Tree gwara kana vaverengi vemangwana vakasara vasina kushanda makomputa uye vachifanira kuvaka zvakare tekinoroji kubva kutanga.
