Hello; I have an Exchange 2003 server and have been doing backups of the Exchange store since I started the server about 2 years ago. The middle of December, 2005, my backups failed and I stopped backing up the store until I purchased a new backup unit. I noticed that my hard drive was filling up very fast. I checked my log files in the MDBDATA directory and the files were not being deleted because I was not backing up . I deleted several of the files to free up about 3 gig of space. I started backing up shortly after and noticed that since I restarted my backups, using Microsoft Server 2003 Backup, I noticed that my log files are not being deleted. I still have log files that are going back to December 20, 2005. Any thoughts?
