database backup: sessions + whos_online tables in General Add-Ons Support Posted June 22, 2012 · Edited June 22, 2012 by xvoyance Because you don't want to start with those outdated data in those tables. so...don't back up, and discard already backup data for those two tables? If I restored these two tables will it cause problems? I undertand whos_online is inmaterial. But how about an out of date session information?
