[Server-devel] backup server

[Rodolfo D. Arce S.]

The moodle directory is /var/lib/moodle, that's for the files and
data, but the database, could that be backed up as a binary database
file? i had some expriences with mysql (not ps-sql) that didn't work
so well, should and "export" of the database work better for that?

cheers.. R
