is "svnadmin dump" a safe/atomic backup mechanism?
Let's say that I want to make a backup of a repository by running
"svnadmin dump", and for whatever reason, I can't prevent client
access to the repository during the process.
What happens if a client commit is in progress when I run the "svadmin
dump" command? Will the "svnadmin dump" command fail? If it doesn't,
will the resulting dump file create a consistent repository if loaded
with "svnadmin load"?
What happens if a client attempts to start a commit while the "svadmin
dump" command is in progress? Will the commit block until the
"svadmin dump" command completes, will the commit abort/fail, or will
the commit abort the "svnadmin dump" command? If the former, will the
resulting dump file create a consistent repository if loaded with
"svnadmin load"?
Thanks,
James

Don't forget to back up your hook-scripts separately, since they aren't included in the dump.

It should work just fine. I don't know whether dump will include revisions committed or not, but you won't end up with corrupt dumps.
