Are you serious? If the source of the calculations hasn't been modified
in some time, then what you do is restore it from the backups. Same as
if it was modified recently.

The older files weren't backed up recently because they hadn't changed.
They didn't get erased from the backups, so they're still available for
restoration, just like the recently changed files.

Did you think that all backups older then one day were somehow erased?
