Unless you're using synchronous replication to clone *every* transaction
on commit to a spare machine, you'll still lose transactions on a
failure no matter how good your backups are.
Even if the OP was doing nightly dumps, they'd be entirely justified in
wanting to try to get a more recent dump on failure.
If they're not backing up at all, yes, that was dumb, but they know that
now. Asking for help isn't unreasonable, and this isn't a stupid "just
google it" question. They've made an effort, posted useful info and log
output, etc. Please don't be too hard on them.
