NDMP Copy from Primary Pool to Offsite Pool

[Will Clopein]

All,

I have just configured NDMP based backups for our NetApp filers. I am able to backup to the primary pool (which is a NetApp VTL) and I am now trying to copy or migrate this data to physical tape so I can send it off-site.

When I try to backup the primary NAS storage pool I am getting the following:

ANR2767E BACKUP STGPOOL: The data format of storage pool NASPOOL does not match the data format of storage pool NDMPOFFSITE. (SESSION: 78)

I believe that I can have the Filer copy between storage pools, but I am trying not to use the filer to copy the data (due to overhead). The dataset is about 11TB.

I would be interested if anyone else is using VTL infront of Tape for NDMP backups, and how they are getting it to physical type.

I thought that DRM (Disaster Recovery Manager) might work, but running into same issues of not being able to copy the storage pool.

I am using TSM 5.5 Extended Edition.

I would appreciate any help or suggestions.

Thanks,
Will

hi will,

how do you define the copypool? dataformat=NETAPPDUMP

cheers ingo

Ingo,

It is defined as NETAPPDUMP. I did some more research, and looks like I have to define a datamover for the off-site pool, and have the filer handle the data copy from pool to pool. I was hoping that there was some way to have TSM copy this data since it is about 11TB of data and will tie up the prod filers for the copy.

Hey Will,

did you manage the ba stg? I have the same problem this days...

backup stg NDMP pool

Running TSM 5.5.2.0 on SLES9 SP4.
Have NDMP setup and it is working for primary stg pool.
The data format is NetApp Dump for the primary and the copy pool.
Have the datamovers setup.
When I try to backup the primary pool to the copy pool is failing, with "drive path or data mover unavailable".
Did you get it to work in your environment?

I dont believe you are able to migrate NDMP data from disk to tape (copy pool) until version 5.5 or TSM. We ran into this about a year or so ago and ended up migrating to a newer version of TSM to make it possible.
