This is a nice solution if you can get the speed out of it. I prefer doing
backups this way as large NDMP streams fail and cause havoc when you have
to restart it.

You can then setup a 'catch all'  policy that backs up All Local Drives,
or all the mount points, but has exclusions for everything you've
specified in the other policies. This way when someone adds something and
doesn't inform you, it's still protected.

Subject: [Veritas-bu] NDMP backups

forget NDMP with Isilon.....there is much better method, which I have only
done with NFS.

Take your media server and hard mount UNC to each individual node.

take the number of subdirectories in the root and divide by the number of
nodes

yes it might not be an even number, but you'll have slight imbalance..1

yes...you could script to check for subs in root and chop it up evenly and
update backup selections

Or, if you have tight controls where you work...anytime storage admin
creates a new subdirectory in root, you are notified to rebalance backup
selections.

then set backup selections as follows

For example: you have four nodes and 16 subs

NEW_STREAM

//unc-path-node1/ifs/directories 1-4

NEW_STREAM
//unc-path-node2/ifs/directories 5-8

NEW_STREAM
//unc-path-node3/ifs/directories 9-12

NEW_STREAM
//unc-path-node4/ifs/directories 13-16


what this winds up doing is making the Isilon use its backplane
(Infiniband) between nodes because that's what its meant for...the
collective throughput of many connections to many nodes being hit all at
once.

10GbE on media server really rips!!

I've seen 500+ MB per seond
