We have configured, Netbackup with Pure Disk setup. we are taking 17 TB backup. Now customer is requesting us to configure Dupllicate backup to tape for higer retentoin. 

My question is > i see full backup logs shows 17 TB backup has been completed and SLP duplicate jobs shows only 3.8 TB of data writen and no errors found.

Can you elaborate the hierarchy of your SLP policy ?

Is this the backup done for the first time or you are seeing this behaviour on repetition

Please show us where you are seeing these two numbers:  17TB and 3.8TB.

Can we assume that the 17TB is not written by a single policy or backup job? How many duplication jobs run after the backup jobs/window? Can you confirm that all policies have been changed to SLP backup destination? Are you aware that only new backups will be duplicated, not previous ones before SLP config?
