As noted before, when you specify a backup store in the Postfix memcache client configuration file, Postfix memcache client will update both the memcache and the backup store. That includes adding entries and deleting entries that are too old. *Some* Postfix memcache client will need to remove old entries from the backup database. If the text in memcache_table(5) is incorrect, report a bug. Wietse
