Dumping PostgresSQL database wavelets ..
.. dump failed! <pre>pg_dump: [custom archiver] could not open archive file "/tmp/.webmin/359009_2_backup.pl/wavelets.scipy.org_postgres_wavelets": Permission denied
I get the above error when backing up with Virtualmin, despite PostgreSQL module successfully backing up. Virtualmin.com exhibits this problem, but backing up the virtualmin.com domain takes too long to be useful as a test case. I'll set you up another test case, if you need one.
