Dear community,
we are running NDMP-backups from an EMC-NAS.
Some policies contain singular directives in the Backup Selections:
set snapsure=y
/root_vdm_1/fs_homes/Homes
These are the policies for the big filesystems that consume quite a lot of time.
The applied Storage Unit in this case has got for Maximum concurrent write drives the value of 4. (As we have 4 drives).
At the end of last weekend I observed that the 3 largest (remaining) policies were running parallell, but using only1 drive per policy, thus leaving 1 drive unused.
Especially with backing up the large filesystems we barely make it through the weekend and we would like to use as many drives as possible.
Is this a standard behaviour for backing up singular filesystems with NDMP, as I am used to see with non-NDMP backups that the drives in such a case are all in use and the load is spread over the drives ?
Thanks in advance for the answers !
Kind regards,
Jaap Hartog
