VTL and Dedup ( TS7569G)

[Sabar Martin Hasiholan Panggabean]

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
