problem with jobs on deduplication volume

Hello.
I'm having a problem running jobs on the deduplication disk.
At startup, the server connects to the BE agent on the hyper-v host, passes the job parameters, but then depends on the status "execution" and the current operation "scan backup".
It has also been noticed that there are problems with tasks of the Exchange and Hyper-V types, but if the backup is launched via the BE agent or SQL type, then the tasks work fine.
Also, jobs of all types on Normal disk and Cassette are performed without problems.
Below are parts of the logs that may give a hint to the solution, but I could not find a solution.

  • so the problem only happened on Exchange VM, right?

     

    Backup Exec 21 Best Practices (veritas.com)

    • Veritas recommends that you do not send an incremental GRT-enabled Exchange backup to a deduplication disk storage device. The transaction logs contain primarily unique data that does not deduplicate well. For best results, create a backup definition that runs a full backup of Exchange to a deduplication disk storage device, and then runs an incremental backup to a disk storage device.

  • Thank you for your reply.
    Yes, that's right, but my problem is that the tasks on the deduplication disk hang at 0kb in the "Running - backup scan" status, while the same tasks are running without problems on a normal volume.
