Bingo. Or even better IMHO:

1. Yesterday. (most recent nightly)
2. Day before yesterday. (old nightly)
3. Last week. (nightly from seven days ago)
4. Last month. (recent nightly from the 1st of the month)

Optional:

5. Month before last. (Two months ago)
6. Three days ago.

These will more than take care of most situations! 90% of the time you'll just want the most recent nightly backup anyway.
