Synopsis

svnadmin dump REPOS_PATH [-r LOWER[:UPPER]] [--incremental]

Description

Dump the contents of filesystem to stdout in a “dumpfile” portable format, sending feedback to stderr. Dump revisions LOWER rev through UPPER rev. If no revisions are given, dump all revision trees. If only LOWER is given, dump that one revision tree. See the section called “Migrating a Repository” for a practical use.

If the size of your Subversion dumpfile is a concern, you can use the --deltas switch to (in some cases drastically) reduce the size of the dumpfile that svnadmin creates. With this switch, instead of writing the full content of each revision to the dumpfile, svnadmin dump will only emit the differences from one revision to the next. There are, however, disadvantages to creating deltified dumpfiles—it's more CPU intensive to create them, svndumpfilter can't operate on them, and non-deltified dumpfiles tend to compress better.

Switches

--revision (-r)
--incremental
--quiet
--deltas

Examples

Dump your whole repository:

$ svnadmin dump /usr/local/svn/repos
SVN-fs-dump-format-version: 1
Revision-number: 0
* Dumped revision 0.
Prop-content-length: 56
Content-length: 56
…

Incrementally dump a single transaction from your repository:

$ svnadmin dump /usr/local/svn/repos -r 21 --incremental 
* Dumped revision 21.
SVN-fs-dump-format-version: 1
Revision-number: 21
Prop-content-length: 101
Content-length: 101
