Hi,
 
I have specific issue here in Netbackup 7. Master/media server  is same --  solaris 10
 
Backup is not spanning media. let me put forward an example
 
Policy : A with 3 clients , volume pool : VP1, schedule : Inc
 
Yesterday policy run at scheduled time - took 3 scratch and wrote 70-80  GB data on it, rest tape is empty. Scratch media is assigned VP1 volume pool 
Today again policy run at scheduled time - took again 3 more scract tapes and wrote 40 - 50 GB data on it, rest tape is empty. Scratch media is assigned VP1 volume pool .
and i run a manual backup again for this policy and 3 more scratcn tapes are picked up.
 
So the issue is Netbackup is picking up scratch tapes each time a backup runs and tapes of yesterday and today which still have considerable amt of space left  ,are not getting appended.
 
- Checked master and media host properties...spanning is checked for media and disk.
- in bp.conf, ALL_Media_Overwrite entry is there in bp.conf
- Tapes are not frozen/suspended
- Same schedule runs each time - Incremental
 
We are falling short of scratch tapes and have no idea how to fix it. Please help me !!!!!
 
Regards'
Sam
