A job performed with encryption, that spans tapes, fails with the error "Job manager lost message channel unexpectedly"
The job manager trace returns the following:
0 PLGLIB :33408 10003 0 195729.347699 C:\BUILD\Windows\HALO_2010AUG12_805205\source\base\library\plugin\plgbackupstreamtape.c:2633: assert(FALSE == oStream->bBlockEncrypted)
0 PROCESS :33408 209 0 195729.347699 Crash program
If encryption is disabled the job will span and complete successfully or if the job does not span it will complete successfully.
Disable the compression on the tape drive. This must be done on the software and on the hardware level. Please consult with tape drive's manufacturer on how to disable the hardware compression. On netvault go to Device Management - locate the drive - select it and right click on it- Select Configure. In the new window -go to the configuration tab - and turn the compression off.
If turning compression off is not suitable - then increase the Media Reserve. The Media Reserve settings needed to work around this issue go beyond what can be achieved through the Netvaut GUI.
