I had a question regarding backing up my database. I upgraded from vBulletin 4 and that all went well. Before moving to Xenforo, my vBulletin database was averaging about 1GB in size, and I would backup usually from phpmyadmin. When I tried recently to backup the Xenforo database, it was around 15MB. This size discrepancy was so big that I wasn't sure it could be attributed to just vBulletin bloat. So, my question is, are posts etc still stored in the old database that was being used for vBulletin, and should I continue to back that one up? Or is Xenforo really that marvelous that the database is only 15MB?
