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.

              Warning | 
|---|---|
| 
                 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.  |
