svn-fast-backup

svn-fast-backup(1)					      General Commands Manual						svn-fast-backup(1)

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 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.

OPTIONS

       -h, --help
	      Shows some brief help text.

       -q, --quiet
	      Quieter-than-usual operation.

       -k, --keep=N
	      Keep a specified number of backups; the default is to keep 64.

       -k, --keep=all
	      Do not delete any old backups at all.

       -f, --force
	      Make a new backup even if one with the current revision exists.

       -t, --trace
	      Show actions.

       -s, --simulate
	      Don't perform actions.
