I am wondering if there is an easy way, ie like a simple cron job, to regularly pull from a remote git repository to a local read only mirror for backup purposes?
Ideally it would pull all branches and tags, but the master/trunk/head would be sufficient.
I just need a way to make sure that if the master git server dies, we have a backup location that we could manually fail over to.
First create a mirror with
git clone --mirror [email protected]:repo.git
then setup a cron job like this:
*/1 * * * * gitbackup cd /backup/repo.git && git fetch -q
This will backup the changesets every minute. Maybe you want to do this less frequently.
do you have direct access to the server? then you could just rsync the .git directory
As Andrew noted, every clone of a git repo is a full-fledged backup of the repo. That said, if you want something backed up automatically to a particular machine, you can create a bare repo on the backup server, push into it with all the branches you want backed up in order to initially populate it. Then just setup a post update hook on the "main" repo so that as soon as there are commits pushed in, it goes ahead and pushes them to the backup repo. No need for a cron job or rsync, and its an almost live copy.
