svnadmin hotcopy — Make a hot copy of a repository.
svnadmin hotcopy REPOS_PATH NEW_REPOS_PATH
This subcommand makes a “hot” backup of your repository, including all hooks, configuration files, and, of course, database files. You can run this command at any time and make a safe copy of the repository, regardless of whether other processes are using the repository.
Prior to Subversion 1.8, svnadmin hotcopy always
made a full hot copy of the source repository. Beginning with
Subversion 1.8 it supports incremental copy to the existing
destination copy of the same source repository. By passing the
--incremental option to
svnadmin hotcopy, you can instruct Subversion to
copy only new revisions and revisions which have changed in size or had
timestamp modifications. The UUID of the hotcopy destination
repository must match the UUID of the hotcopy source repository.
Incremental hotcopy mode is supported for FSFS repositories
If you pass the
svnadmin will perform a hot copy of your
repository, and then remove unused Berkeley DB logs from
the original repository.
As described in the section called “Architectural Limitations”, hot-copied Berkeley DB repositories are not portable across operating systems, nor will they work on machines with a different “endianness” than the machine where they were created.
