Hi Yes, you can share it with multiple backup applications by defining more than 1 library. Each library needs it's own dedicated drives though (as with all VTL's).
Since TSM & BackupExec writes information differently to the VTL, data backed up using TSM wont be deduped against data backed up with BackupExec. If this has any impact on your dedup ratio depends on the amount of information you store with each application. At a certain point, TSM will have enough "own" information stored to dedup against, and so will BackupExec. Hope that answers your question.

If yes, will this affect deduplication ratio? Please compare it with the case if all systems send their backups to a single solution: TSM+VTL. Thank you, Mehdi
