NDMP NAS restore performance

martin3399

Newcomer
Hello,

we have a problem with our performance when performing NDMP restores. We configured the 3-way-solution.

We are testing a new file server where we are already successfully backing up the data to tape using NDMP.

600 GB of data are transferred in 45 minutes. But the restore takes 14.5 hours. The TOC is created during the backup.

The relevant data is located on a single tape.

Can this be related to a configuration issue on our side or is it really the case that the restore is significantly slower?

The backup command was:

backup node VBERLIN2_PBLU_PRD /vberlin2_fs1 mgmtclass=MGM_KEEP3VER toc=yes mode=full

The restore command was:

restore node VBERLIN2_PBLU_PRD /vberlin2_fs1 /vberlin2_fs2_restore

The copygroup with the destinations looks like followed:

Policy Domain Name: FS_ARC

Copy Group Name: STANDARD
