We have a weird occurence in our company. Our network administor was looking over backups on SQL server and it appears the size of database went from 8 gigs to 10 gigs overnight between 6pm and 7am the next day. We have no employees that hits the database during non business hours so we aren't sure where all that data came from. The log file was also about 5 gigs when normally it should be about 20 to 50 megs. What is best way to try to solve this weird occurence? I tried looking at each size of the table and rows but nothing out of the ordinary sticks out. Thanks in advance for your help.
