An incremental backup policy configured to protect the data disk of a Microsoft SQL server runs
once every 2 hours. This policy is configured with 48 generations, and the first full backup was
done on Sunday to the server. On Monday, Tuesday, and Wednesday, the incremental backup
total size resulted in a backup of 50 MB for each snapshot. On Thursday the 2 a.m. backup was
noted to be 4 GB by the IBM Tivoli Storage Manager FastBack (TSM FastBack) Status Monitor,
and was still a backup type of Incremental. Assuming that no software was installed or removed
on the server, and that there was not any change in usage patterns by users on Thursday, what is
the likely cause of the increased backup?

A.
The server was rebooted.

B.
The TSM FastBack client was restarted.

C.
Microsoft SQL backup was performed creating a full dump of all the SQL databases.

D.
TSMFastBack scheduled a full backup, because the policy has 48 generations, and the full
backup taken on Sunday expired.
