Hi,

Currently I have the following situation;

Two Netapp files being backed up via NDMP. Each filer is attached to a
jukebox with 2 drives. The drives are assigned to each jukebox, ie 1:1.
The index files generated are backed up to a second jukebox directly
attached to the Legato server.

Because there is a mismatch of disk capacity on the netapps, one
finishes well in advance of the other on incremental and full backups.

I would like to reconfig the drives to pool the drives, ie netapp1 takes
both drives and completes ndmp operations. It then releases the drives
and they are taken by the
second netapp. This will improve utilisation of resources ( the under
used drive on the smaller netapp ) and shorten the backup window for the
filers as a whole.

Is these feasible, and if so, are there any pointers on setting up or
operational issues. One thing that springs to mind is if both filers are
set to backup at the same time, and one grabs both drives, will the
second one simply wait for the drive or will the ndmp timeout and backup
fail ?

Tks for any assistance.

-Bob
