NAME
       svn-backup-dumps - Create dumpfiles to backup a subversion repository.

SYNOPSIS
       svn-backup-dumps <repos> <dumpdir>

DESCRIPTION
       svn-backup-dumps  creates  dumpfiles from a subversion repository.  It is intended for use in
       cron jobs and post-commit hooks.

       The basic modes of operation are:

       •      Create a full dump (revisions 0 to HEAD)

       •      Create incremental dump containing at most N revisions.

       •      Create incremental single-revision dumps (for use in post-commit).

       Dumpfiles are named in the format basename.rev.svndmp or basename.rev.rev.svndmp, where base‐
       name is the repository directory name, and the rev arguments are the first and last  revision
       numbers represented in the dumpfile, zero-padded to 6 digits.

       Optionally, svn-backup-dumps can compress dumpfiles with gzip or bzip2, and can transfer them
       to another host using FTP or SMB (using smbclient).

OPTIONS
       --version
              Show program's version number and exit.

       -h, --help
              Show this help message and exit.

       -b     Compress the dump using bzip2.

       --deltas
              This is passed through to svnadmin dump.

       -c count
              Maximum number of revisions per dumpfile.

       -o     Overwrite files.

       -O     Overwrite all files.

       -q     Quiet.

       -r rev Specify a single-revision dumpfile.

       -t ftp:host:user:password:path
       -t smb:share:user:password:path
              Transfer  dumps  to  another machine using the FTP or SMB protocols.  path is where to
              store the dumpfiles on the remote server; any occurrence of %r in the path is replaced
              by the repository name.  Support for "smb:" requires the smbclient program.

       -z     Compress the dump using gzip.

EXAMPLES
       To create a full dump of  all  revisions  of  a  repository  /srv/svn/foo  in  the  directory
       /var/backup/svn:

       svn-backup-dumps /srv/svn/foo /var/backup/svn

       The dumpfile will be named src.000000-NNNNNN.svndmp.gz where NNNNNN is the head revision num‐
       ber.

       To create incremental dumps containing at most 1000 revisions:

       svn-backup-dumps --deltas -z -c 1000 /srv/svn/foo /var/backup/svn

       If the youngest revision is 2923, it creates the following files:

              foo.000000-000999.svndmp.gz
              foo.001000-001999.svndmp.gz
              foo.002000-002923.svndmp.gz

       If run again, later, when the youngest revision is 3045, it creates these two files:

              foo.002000-002999.svndmp.gz
              foo.003000-003045.svndmp.gz

       Note that it does not remove the redundant file foo.002000-002923.svndmp.gz.

       To create incremental single-revision dumps from a post-commit hook:

       svn-backup-dumps -r $rev $repos /var/backups/svn

       where $rev and $repos are variables previously set in the post-commit script from its command
       line.  The dumpfile name will be in the form foo.000352.svndmp.

       To  send  the  dumpfiles  to the SMB share \\ERNEST\BACKUPS in a directory \svn\foo with user
       svnuser and password w0rth1ng:

              svn-backup-dumps   -t    "smb://ERNEST/BACKUPS:svnuser:w0rth1ng:svn/%r    /srv/svn/foo
              /tmp/tmpbackup

       Note  that the %r in the path is replaced by the repository name foo.  Note also that a local
       backup directory is required, at present, even when using the -t option.
