Since there are no naysayers and I'd really like a full archive backup
soon, and since Bluewind told me in IRC that the boxes work well, I'll
just go ahead now get a BX60.

I'll then sync vostok to that box overnight and after verifying that I'm
able to read/write backups from all current backup clients on the new
box, I'll start decommissioning vostok. I won't delete any data or
cancel boxes without at least one other person checking that work, though.

Wish me luck!

Sven
