Re: [Veritas-bu] Using multiple drives with NDMP.

Hello Jeff,

It works for me. I have two policies via two different media servers and they run at the same time, I tried and tested to run multistreamed backup policy and it was running fine as well. Double check your settings on the storage unit and make sure you have "Allow multiple data streams" checked on the backup policy with NDMP policy type. In my case, I am getting the same speed, 65 to 75 Mg/s for both jobs running at the same time, if I run the multiple stream policy, then I am getting just around 30 mg/s per stream. I have Celerra filers. Hope it helps.

regards,
Boris

Greetings,

I've got just about all the bugs worked out of the new test environment except 1. I can get my NDMP policies to back up more than one file system at a time.

I've got a 6.5.3 environment running on linux. I've got a library (tld0) with 4 Gen 3 Ultrium drives. I've defined a media manager storage unit because I'm doing remote NDMP. I've set up 3 test policies, 1 standard and 2 NDMP. All policies work fine one at a time, or either NDMP policy will run at the same time as the standard policy. The storage unit is set to allow the use of 4 drives and also allow multiplexing (for the standard policy). The policies vary on the number of jobs per policy. One is set to 9 and the other is not set. One NDMP policy has 3 file systems to back up and the other has 1.

When I run the policy with 3 file systems, it only runs one at a time to one tape. The other 2 just queue. I've tried putting in the new stream directive between them in the includes file but it didn't help. I can get them all to work one at a time but can't get them to backup more than one NDMP file system at a time. Is there some bp.conf directive I need to create?

Any help pointing down the correct path would be appreciated.

Thanks,

Jeff
