Getting low throughput for NDMP backup jobs.
In our backup environment we are using Backup Exec 12.5, we are facing low throughput (Job Rate) issue for some of NDMP jobs, Filer is EMC celerra.
In the Window Events we are generally see the events ID:33152, Adamm mover Error:Get Drive info failure, Error= ERROR_GEN_FAILURE for some drives. while checking the drives we are able to see all medium changer & Tape Drives with proper HP drives.
We are using HP MSL4048 G3 Series Tape Library with LTO4 tape drives & medias.
Could you please suggest me how we can increase the throughputs for NDMP jobs. And which drivers we should be installed on Tape Drives- HP or Symantec?
Due to low throughput its taking a very long time to be complete or some time we need to cancel the jobs as we cant run the job in business hour.
Any suggestion or help will be greatful for me...
Thanks in advance...
