Hi Rajesh,

could it be that you only have data for a small amount of nodes in your server? 
Or that there is one exceptionally large node? IIRC bacup stg for DISK works by 
node, so if one process is working on the data of the last node, the other 
process will finish if there is no data of other nodes to backup. This is 
different for FILE and tape volumes, there backup stg works per volume.
