I have a SQL Server that with 4 drives. On drive E I store the mdf file and on drive F (SAN) I store the backup .bak file. The storage size for both drives is about 630 gig.
In the last running of the database it grew to over 600 gig. Then I wanted to see what the backup file grew to and it is gone, acutally it went to 2kb.
Could it be that last Thursday I have a job in SQL Server Agent that runs the weekly backup. When that ran since it overwrites the previous backup that it removed the current bak and there may not have been enough drive space to rebuild and hence I have what I have?
