I think what Lawrence meant was that say full backup takes 33GB, as
the one below.

| 1,089 | tic FS          | 2011-01-08 02:05:03 | B    | F     |
464,798 | 33,390,404,320 | T         |

Now, if you do Incremental backup, it's going to be reported by
bconsole as even bigger, eg.:

| 1,097 | tic FS          | 2011-01-09 02:05:03 | B    | I     |
6,573 | 39,758,701,241 | T         |
| 1,105 | tic FS          | 2011-01-10 02:05:08 | B    | I     |
4,585 | 39,502,153,253 | T         |
| 1,113 | tic FS          | 2011-01-11 02:05:02 | B    | I     |
4,585 | 39,808,375,917 | T         |
| 1,122 | tic FS          | 2011-01-12 02:05:02 | B    | I     |
4,441 | 39,939,208,908 | T         |
| 1,130 | tic FS          | 2011-01-13 02:05:03 | B    | I     |
7,584 | 40,036,714,059 | T         |

This is something that I don't have an answer for and I guess it's
somewhere within the documentation and I have missed it.  Logically to
me would be to show only how much Incremental backup took space, not
the total of the last full + incremental.

Kind regards.
