Is this accurate? Depends what your goals are. If you only want to be able to recover the latest database state then you only need archived WAL segments back to the start of the latest filesystem backup. If you are interested in the "PITR" aspect of it --- being able to revert back to last Tuesday before some bad guy injected bad data, say --- then you'll want to keep older filesystem backups too, and a continuous string of archived WAL files covering the period of interest. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
