i had a little problem about backing up 2TB from a NAS to tape via Dataprotector. After nearly 8 hours a approx 500 GB Total Data i got this error message:
Major] From: BSM@cellserver "ARCHIVE" Time: 04.08.2016 16:00:01
[61:3003] Lost connection to MMD named "noname"
on host cellserver.
Ipc subsystem reports: "IPC Read Error
System error:  Verbindung wurde von Peer zurückgesetzt
I googled and find a solution on data-protector,org
but the solution is for DP7, i wonder if is applicable for DP9 too.
