Because you only have one NDMP device, you should set either the client 
parallelism, or the NDMP pool's max parallelism equal to 1.  This will ensure 
that only one saveset is processed at a time.

For backups to NDMP devices, each device can only process one stream.  
Multiplexing is not allowed.

If the savesets are processed one at a time, the save group will have 2 
savesets in the work list, and process it one at a time.

Timeouts typically happen if NetWorker thinks that the client is not 
responding.  That would not apply here, especially if you are performing full 
backups.

Note:  for NDMP backups, if you are performing non fulls (i.e level 1-9), then 
there could be inactivity at the filer level that would cause NetWorker to 
timeout.  Because of this, set the save group's inactivity timeout to a higher 
value than norm.  For example, set it to 120 mins.
