I have inherited a server running SQL Server 2008 R2 and it keeps running out of space. After doing some digging with WinDirStat, I found that it is almost entirely due to the SQL Server backups folder, which has backups going back for years that have never been cleaned up. In SQL Server Management Studio, however, I do not see any defined maintenance tasks for regular backup, so I can find no way to turn them off.
Per this thread, it looks like it safe for me to go remove those old backup files, so that will deal with my imminent and routine space problems. I would like to confirm that if possible with someone who actually knows what they're doing.
Beyond that, can anyone point me in the right direction for figuring out how these backups are defined? With no defined maintenance tasks, I'm at a loss as to how they keep happening. I'd like to adjust the automatic backup cadence and automate some clean-up to help keep this under control in the future.
