Some background... We have an Overland ArcVault 800, 24 tapes, 1 drive. Symantec BackupExec 11d.
We are running LTO3 "800GB" tapes. As I understand it, these tapes are 400GB tapes in "native mode" and 800GB with compression. I will never actually see the tapes' capacity extend to 800GB because of compression variables. But it should AT LEAST expand a little beyond 400GB. On the contrary, I am getting 391GB out of every tape. How can this be changed? How can I get better functionality out of the ArcVault?
