Scheduled Database Backup job fails due to lack of disk space Two of my scheduled SQL Server backups failed over the weekend because of a lack of space.

The C: drive has 25.3 GB of free space out of 400 GB. The primary space taker is SQL.


149.9 GB C:\Program Files\Microsoft SQL Server\MSSQL\BACKUP
139.7 GB C:\Program Files\Microsoft SQL Server\MSSQL\DATA


Any suggestions as to how to fix this problem? Please help! I'm a rookie DBA confronted with this issue
(Can post this as comment due to lack of rep)
