Hi James,

just to mention:
since SV/SM is based upon SnapShots that are by design *readonly*, it's not possible to 'wipe' them through file system means. But if a hacker actually gains access to the destination filer itself and messes with it (e.g. vol destroy)...

And yes, you can SMTape. (Neat thing: it keeps dedupe savings, as opposed to NDMP-based backup)
smtape

Thanks everyone for your insight.  A VTL isn't in the budget at this
point, and candidly I'm not totally sold on the combination
snapmirror\snapvault with a pair of filers
geographically separated being insufficient, but the client has a
particular need.

I'm pretty happy with SV to a geographically diverse filer, but on
another mailing list I'm on there's some discussion about how any online
backup could be wiped by hackers. I have no interest in setting up a
tape infrastructure, so what options are there for offline disk backup?
Can you SMTape to disk? NDMP perhaps?

Thanks,
