Single file? Multiple files? How much of it changes over time?

My point: add another disk; use something like rsnapshot (if you're on Linux) or Time Machine (on a Mac) to ship the deltas to another disk.

Or, if it's multiple small files that change independantly, use source control (e.g. Subversion, Mercurial or Git).
