Hi Martin,
The 1st Backup will probably don't do any major save for you. It always depend 
on what kind of data you backup.
What we normally see is saving on Archive Data and TDP Data. Everything else is 
most of the time unique data and you will not see any saving.

Dedup is a major saving for other backup software such Legato and NBU not for 
TSM because you are using Incremental forever.

Hi,


Does anyone here has been implementing or know how Dedup works in TSM using 
TS7569G ? Let say I have 100 TB of data and backup to this VTL. On the 1st 
attempt of backup / full backup, will this data size decrease on the VTL

BR,

Martin P
