I know that AppAssure is not a "tape product", but Dell has been promising that AppAssure would include tape backup functionality in the next release. I have not installed 5.4 yet, but I didn't see it mentioned anywhere in the release notes.
When does Dell plan to include tape functionality in AppAssure?
AppAssure and NetVault on the same server is not supported by Dell. As you can imagine both AppAssure and NetVault are part of 2 seperate teams........ We have been chasing this for a long time for Archiving to tape and we ended up building a application (and OEM applicance) to enable AppAssure to use NetVault as the Archiving engine to tape.
I apologize using the wrong name in my reply to your question!
