The drive docking stations which are now available, make this easy:

and others...

With a dock, you can just buy bare drive mechanisms as needed.  I like
to use 2.5" mechanisms because they are so compact, although I'm not
sure whether a 750 GB 2.5" drive or a 3 TB 3.5" drive has a greater
volumetric data density.

Get a safe deposit box.  You ought to have one anyway.   If it's
small, use 2.5" drives, which the docks above also support.    Rotate
one set of backups out to the safe deposit box on some kind of
schedule.

Even if you don't stick to the schedule, having some kind of back up
off site is better than nothing.  It may not be up to the minute, but
at least it will preserve most of your stuff.

I keep thinking about setting up a bank of BD-R drives, because
Retrospect will move to the next available drive as it fills the
first.  So with several, one can load them all with blank media and
only need to come back every hour or two to swap media.  However, I
think hard drives are (or were, before the flooding) actually cheaper
per GB than blank BR media.

It takes about 100 BR disks to equal one 2 TB hard drive.   Recently
I've seen the BR blanks at about $35 per 50.   So $70 per 2 TB.  And
this summer hard drives were about $70 per 2 TB. Sigh.
