a wal archive plus occasional basebackups lets you restore to any point
in time (PITR) covered since the oldest basebackup.
think of a base backup as a 'full' backup, and the wal logs in the
archive as incrementals. one such approach might be a weekly
basebackup, where you keep the last 4 weeks, and keep all wal files
since the start of oldest basebackup. yes, this will take quite a bit
of space
