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.
