However there is the use case for people that just want a minimal backup solution that works for their specific environment, and don't want to bring along a lot of extra machinery that a full coverage all-singing-and-dancing product includes - this *can* be accomplished by a few shell scripts. Yes, it does mean that you spend extra time testing and debugging [1]. Err - I think that is all the original author (who is probably scared off now), was wanting a bit of help with. regards Mark [1] which is where a pre-existing more complex solution is likely to be better - it has had more testing in the field, and of course it is fine to point that out. -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
