NAME
svn-fast-backup - very fast backup for Subversion fsfs repositories.
SYNOPSIS
svn-fast-backup
[-q]
[-k{N|all}]
[-f]
[-t]
[-s]
repos_path
backup_dir
DESCRIPTION
svn-fast-backup
uses
rsync
snapshots for very fast backup of a Subversion
fsfs
repository at
repos_path
to
R 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
R --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.
