Re: Best backup strategy for production systems

If your database is relatively small, I would recommend
http://www.pgbarman.org/. It does binary backup and will take care of your
WAL files. The laster version of pgbarman can also take backups from a
slave using pgespresso extension. Note that pgbarman runs over streaming
replication protocol.

If your database is big, go for pg_basebackup and archive_command. You can
run this on a slave. The pg_basebackup will give you the base and during
restore you can use restore_command with recovery_target_time for example
to replay from the archived WAL files.
