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.
