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 basename 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 number.

       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.
