Hello Bob
I suspect that the main problem is that you are
backing up a remote file server using protocols that are not optimized
for this type of activity.
You might want to look at the cifs stats on the netapp box and the
network and fs stats on the nt box. Their may be some way to twist
some knobs to speed things up. But I expect that you might be breaking
new ground here. Maybe the Tivoli and/or netapp support folks could
help with this.
If you are not using nt security for the filesystem then you
might get faster response with a unix client and nfs.
There was some talk that IBM/Tivoli and the netapp folks might do some
work to offer better support for the netapp with the TSM product.
Does anyone have any news on this front?
We have a number of Netapp here, but are using another vendors product,
with the ndmp protocol. This process is much quicker then the TSM
incremental only system, but does use more in the way of media and
drive hardware. I suspect that TSM could handle the ndmp process
with an client written with the TSM api library. But it would have to
be a full/inc backup scheme. But that appears to be what most of the
api clients do.
Or since the netapp is based on the bsd kernel, one would think that
Tivoli could write a client that works on the netapp and does there
classic backups. Of course this would have to be in partnership with
netapp.
Please let us know how you make out with this.
