if Duplicate job failed to run it multiplies backup sets next time
I observed the following behaviour with BE2012SP3.
Full Backup of Server ABC is scheduled to run every MON/TUE/WED/THU/FRI 08:00 PM (to DedupStore, Notification is enabled)
Duplicate of Server ABC is scheduled for every SAT 08:00 PM (from DedupStore to Tape, Most recent full backup, Notification is enabled)
The Full Backup Job still runs on SAT 08:00 PM so the Duplicate doesn't run (WITHOUT ANY Error or Notification!) and schedules itself to the next following Saturday.
Next week and the week after, same situation (NO Duplicate)...
Now I realized, that the Duplicate job didn't run and started it manually with "Run now" option. In that case the duplicate job wrote the triple amount of data to the backup tapes 1.384GB instead of 461GB !!!
I observed that already before, but was not sure if I made a mistake. But now, I am sure, that BackupExec causes the problem.
I don't believe that this is a wanted feature and hope to get some hints how to get only the data of the "Most recent full backup" duplicated to tape!
Many thanks for your help in advance.
