I have the the same problem. I'm running Ubuntu 10.10, ext4 filesystem -
nothing complicated.

I tried both 0.11.3 and 0.11.4 versions of sbackup, and found this problem in both - it adds non-modified files to output file. In the log, and in the notification area applet, it shows reasonable sizes - around 300-500 Mb. But sometimes, when those are backupped, the notification area reaches 100% completion, and the archive grows after it for a long time - up to 6.3 Gb. (The size of full backup is around 10.4 Gb).
In fact, almost all of those 6.3 Gb come from single directory, but it contains only static content - nothing is modified during the day.

Backup log:

As you see, program was going to write 2.5 Gb, and ended writing 18 Gb
instead.
