These are sufficiently large that the problem is harder to resolve, as =
nobody "makes" a 5TB drive I can ship to a colo. Drive failures in the =
"backups" host also become painful to work with as I'm cheap so the ZFS =
pool isn't 100% mirrored.

Stretching the definition of "cloud" (why not, everyone else has), you =
can include SmugMug, Flixter, Picassa, etc. For $20-$40/year (yes, =
_year_), some of these allow infinite uploads.
Moreover, while you only get a few MB/s per session, you can open =
multiple simultaneous uploads. I've filled my upstream pipe uploading =
things - which still takes days, but not 100s of days.
Anyway, this is one way to get an off-site backup, lower your b/w =
requirements on your personal server, and even get someone else to do =
things like make thumbnails, multiple sizes / magnifications, allow =
(paid) prints to be made, etc., etc.
