What about disaster recovery? Assuming I take the approach you suggest and have to restore the cache (with the tested versions) after it's lost in a disaster, is there a way to do that (short of backing it up)? I'd rather be able to keep a list of package versions instead of having to move around entire cache backups across continents.
