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 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 the section called “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.
