git-backup

Simple shell scripts for creating and restoring incremental backups of git repositories using git bundles.

The backup routine uses git bundle create --all last_backup_tag..master to create incremental bundles. After restoring the backup only the master branch will be restored.

Backup

Create a backup of a single repository and save it into /backup:

backup-git.sh /path/to/repository /backup

Create backups of multiple repositories located in ~/projects and save them into /backup:

backup-git.sh ~/projects /backup

Restore

In order to restore a repository named repository into /tmp/git/repository, run the restore script from the directory containing repository_*.bundle files:

backup-git-restore.sh /tmp/git repository

Testing

The simplified test suite clones a repository from a bundle file, simulates a few commits and runs the backup after every single commit.

Afterwards the repository is restored from multiple bundle files.

cd test
./run.sh
