svnadmin hotcopy — Make a hot copy of a repository.
This subcommand makes a full “hot” backup
of your repository, including all hooks, configuration files, and, of course,
database files. If you pass the --clean-logs
option, svnadmin will perform a hot copy of
your repository and will then remove unused Berkeley DB logs from
the original repository. 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.
--clean-logs
As described in Berkeley DB, 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.
