repos_path backup_dir
DESCRIPTION¶
svn-fast-backup uses
rsync snapshots for very fast backup of a
Subversion
fsfs repository at
repos_path to
backup_dir/
repos-rev, the latest revision number in the
repository. Multiple
fsfs backups share data via hardlinks, so old
backups are almost free, since a newer revision of a repository is almost a
complete superset of an older revision.
This is good for replacing incremental log-dump+restore-style backups because it
is just as space-conserving and even faster; there is no inter-backup state
(old backups are essentially caches); each backup directory is self-contained.
It has the same command-line interface as
svn-hot-backup(1) (if you use
--force), but only works for
fsfs repositories.
svn-fast-backup keeps 64 backups by default and deletes backups older
than these; this can be adjusted with the
-k option.
