even wierder.

just noticed this only happened on 2 of the 4 streams

The system is a cluster with 4 virtual servers.
Each virtual server serves up one drive letter (R, S, T, U)
=20
two of the jobs kicked off "proper" incrementals and completed in a
couple minutes, and the other two backed up everything.

        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?
        =20
        Paul
