My database just shot up from 117MB to 140MB in only three days! I'm new to SQL Server and don't know what might have caused this - it wasn't any growth on my site - nor ways to prevent it. Is compacting safe? Also, how do people here back up their database?
It's not really all that unusual to see SQL Databases increase in size like that, SQL Reserves space for inserts etc, you can compress out the space but it's only going to reclaim it again eventually. What Rui suggested will help keep the log file size down most people dont need full transactional logging anyway so the Simple recovery mode is generally more appropriate to use.
