I had a maintenance plan fail last night (runs daily) for the first time in ages. The following is the specific error I received, minus the actual database name:
Extend Disk Backup: failure on backup device 'b:\Mydatabase.bak'. Operating system >error 112(There is not enough space on the disk.).
I use WhatsUp Gold for monitoring and upon looking at the historical report, there was more than enough space left during the point the SQL logs say it failed.
The database is nearly 7GB and there was well over 300 GB of free space at the time of failure.
Is this a fluke or am I missing some inside information?
