Hi
There 3020 configured for NDMP backups has three vols they are as
follows -
/vol/exch_vs1 - this is snapvalt volume on a 3020 filer snap vault'd
from a 980 filer at the production site, the data is Exchange db and
logs snapshots - this ran at 2mb\sec
/vol/exch_vs1 - is snapvalt volume on a 3020 filer snap vault'd from a
980 filer at the production site, the data is Exchange db and logs
snapshots - this ran at 2mb\sec
/vol/vol0 - this is small and I suspect the performance is not accurate
it showed around 2-3 mb\sec but finished in a couple of mins

Subject: RE: [Veritas-bu] NDMP backups very slow
We also use NDMP in this manner. We have found that some volumes on the
NAS backup slower than others. We are still looking into the issue but
our issues is these volume are snap mirrored and for exchange and these
backup twice as slow as the regular volumes we have. Check to see if
these are snap mirrored volumes. Check the fragmentation level as well.
Does the issue happen with all your volumes on the same NAS or just
certain ones?

Subject: [Veritas-bu] NDMP backups very slow
Hi
Can anyone help with this issue?
We have a NetApps 3020 filer connected directly (no FC switch) to two HP
LTO3 drives. The drives are in a SL500 library and the library robot is
directly connected to a windows NetBackup v6.0Mp4 master. We are using
the NDMP licence to backup the vols on the filer over the fibre to the
drives but instead of the expected 40-60mb\sec we are getting 2-3mb\sec
on both the drives.
In NetBackup we have an NDMP storage unit with NDMP host as the filer
and two NDMP drives with the nrstxa paths for both drives. I have
created a NDMP policy to backup the vols using the client as the NDMP
host (filer)
Does anyone have any suggestions?
Kind Regards,
Imran Khan
