I know that this feature was just announced this morning and because v7 isn't out yet, I'm somewhat expecting the "we're not allowed to say just yet" answer, but I'm going to ask anyway.
Based on the video that was posted, it looks like hardware compression will be supported by this new feature, but unless I missed it, I didn't see anything relating to encryption. Will the files that are written to tape have the option to be encrypted? Unless feature announcement 6 or 7 is the introduction of encrypting the native VBR files (which would be awesome, BTW), I'll have unencrypted files being written to unencrypted tapes. If you're like me and store your tapes at an offsite location (and you're not responsible for transporting them there), I'm sad to say that I won't be able to use this feature until there's a mechanism to encrypt the native files or tapes.
Personally, I'd love to see the ability to encrypt my VBR files, so if that's not one of the remaining two feature announcements, please consider this a +1 for that feature request.
As always, thanks for listening!
