Ignoring security, there is also a bandwidth issue.

I'm backing up about 300GB across a T-1.  Not very active, so I'm
sending less that a GB per night most times.

A T-1 basically does about .5 GB/hr., so the nightly activity is no big deal.

But 600 hrs to backup / restore the entire 300GB  dataset is not very
practical for routine use.  ie. a few weeks to do the restore.

So I treat that as a true disaster recovery backup (fire / natural
disaster / etc.).

If I were to lose my production raid array, I would restore from the
local backup.
