I ran a FULL backup of a large windows server on Wednesday night,
starting aft the regular backups had completed.
The policy was configured with only one schedule named "Test-Full"
=20
Yesterday, after the backup had completed successfully, I removed the
"Test-Full" schedule, and added two new schedules called Weekly-Full and
Daily_Cumumlative, of types Full, and Cumulative Incremental,
respectively.
=20
Last night, the Cumulative job ran, but backed up 100% of the data on
the machine......unfortunately, the job was split into 4 streams to two
LTO2 drives, and hogged those drives most of the night, causing some
jobs to fail as their window had closed.
=20
Why would these Cumulative jobs back up everything, when there was a
valid FULL from less than 12 hour before?
