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
switch,
svnadmin will perform a hotcopy 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.
