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_dirDESCRIPTION
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.
