Which to me indicates I need to do a base backup every day...? You just need any base backup plus *all* archived WALs since the beginning of the backup. Of course you want a fairly recent backup, otherwise applying the WAL files can take very long. It is a good idea to keep more than one base backup in case something goes wrong (bad backup). Another reason to keep older backups is that you may want to recover to a point in time that lies further in the past, e.g. if it takes some time to discover a problem that requires recovery (corruption, ...).
