I needed it today, when I found that the estimated size of a backup was greater than the available space on the drive and had to abort the backup - It works, but it just seems a bit clumsy!
ALSO: I know the estimates are ONLY ESTIMATES, but they're usually fairly accurate - or are they? - I reset my main backup and restarted it:
It correctly reported 19GB to be backed up (2 drives).
Estimated size of backup (after compression) 29GB
![Exclamation :!:](./images/smilies/icon_exclaim.gif)
The actual size of the backup was 14.8GB.
The next backup (smaller) reported estimates that were much more accurate.

Just one of those computer glitches!
