I did not really test that but I have some mixed environments NFS and
NDMP.
On average my ndmp is faster at least 10 to 20 times depending on kind
of data being backed up.

Subject: [Veritas-bu] NFS Backups


All,

A group I support here is looking very heavily at a Sun Storagetek
appliance like storage device that I've got to backup somehow.  After
seeing the NDMP price tag (we don't do any other NDMP here) the question
of NFS file backups has come up.  So I'm going to try to benchmark NDMP
backups with the NBU NDMP extension (temporary licenses) versus the same
backups on a client server over NFS.

OBVIOUSLY NDMP to Media Server is the way to go here (not an argument
from anyone on that.)  HOWEVER - apparently from a budget perspective
it's a difficult pill to swallow.

(Ok, my disclaimer is complete - so flame on!)

My current plan is to benchmark to NDMP, then load up a test Linux
server and optimize that NFS backup.  I'm assuming the NDMP will be (for
example) some 50+MB/sec and the wire-2-wire is going to be significantly
slower (the percentage slower being directly related to whether or not
this is even feasible.)

Has anyone done any testing like this before?  I'd appreciate any
results anyone can share.

Thanks,

-J
