You would need to look at one of the replication solutions. I don't know
lot about them.

It depends on what kind of crash. If the machine unexpectedly shutdown,
then should be able to just start the server back up. If you lost a hard
drive then you will need to restore from backup. Note that backing up the
data directory while the postmaster is running will not give you a usable
backup. You either need to use pg_dump or you need to do a backup while
the postmaster is shutdown. There is no point in time recovery available
at this time.
