I have Arcserve 9.01 running on NetWare 6.5 SP3. After upgrading to SP3
from SP2 I have had problems with backups. When backing up multiple
local volumes I get the following error:
E1039 Failed to flush Tape Driver buffer - Drive or Media Failure.

I have a workaround to only backup one volume, and this always succeeds
so I conclude that the tape drive and tapes are fine.

Any suggestions?

Thank you in advance.
