Some records might be missing their SHA-1 in\nthe backup if that particular object wasn't pushed there, but the\nreflog code is generally tolerant of those garbage records.\n\n-- \nShawn.\n"},{"id":"124852","messageId":"194a2c240910130943j40c12902o760e463e7a8ce8fa@mail.gmail.com","threadId":"21212","inReplyTo":"20091012143043.GJ9261@spearce.org","subject":"Re: backup git repo on every commit","fromName":"Israel Garcia","fromEmail":"igalvarez@gmail.com","sentAt":"2009-10-13T16:43:51Z","receivedAt":"2009-10-13T16:43:51Z","isPatch":false,"sender":{"key":"igalvarez@gmail.com","avatar":"https://gravatar.com/avatar/8ccdadcbfb98c0cb0940523de930580bd60319c2802d3dbfce9aeaa7c778116c?d=mp&s=160"},"body":"Hi Shawn,\n\nSorry to ask again, but I'm a little confuse about how git work in my case.\nI use gitosis on a server where I have all repos\n(/usr/local/git/repositories/), so different people clone their repos\non their computers.

E.g. `git clone --bare`.\nSince this leaves you with a directory, you need to then perhaps\nuse some sort of file combiner tool like tar or zip to produce a\nsingle file for backup to tape.\n\nYou can incrementally update that backup clone using git push to\nwrite into it, or you can just blow it away and recreate it each\ntime you make a backup.\n\nOne could also use `git bundle` to create backup file that had\neverything packaged in one neat file, but this can be slightly\nharder to work with since a bundle is not a git repository.\n \n-- \nShawn.\n"},{"id":"124857","messageId":"20091013181843.GZ9261@spearce.org","threadId":"21212","inReplyTo":"194a2c240910131108h10acbacdy68306c9c3389517@mail.gmail.com","subject":"Re: backup git repo on every commit","fromName":"Shawn O.
