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.

Best Regards

Hi,
Can a VTL like TS7650G be presented to more than one backup servers (like
TSM and BackupExec) simultaneously? 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
