No, there is a difference here.

If you want your database to be up 24x7, then obviously you need some
sort of replication.  If on the other hand it's a casual website which
can be down for a few hours while things get restored from backups,
then replication isn't needed.

ACID compliance _is_ necessary though because without that your
database gets silently corrupted, and the corruption ends up in your
backups.

FWIW, I have found PostgreSQL to be extremely reliable, and if you
really want replication then you can probably do something with Xen &
LVM.
