within Backup Set´s of a Server i can see the last Backup Sets and where the data is stored.
I have some Backup 2 Disk -> Duplicate to LTO Jobs.

In the Backup Set´s i see the size of Snapshot Full to my Disk Storage, reporting a size of 2.27GB

The same size of the Duplicate Job, shows about 101GB on LTO.

I use Symantec Backup Exec 14.2 (1180) with Feature Pack 4.

Why is there any difference ?
