Hi,

The size of my incremental backups seems to be very large. On 29/1/2011 I did a full backup, which came to 12.7GB. I've configured sbackup to do a full backup every 30 days.

Today I ran a backup. It detected that it should be an incremental backup, but it wants to transfer 11086MiB. I'm pretty sure I haven't created another 11GB worth of files in 7 days! I can't see why it wants to transfer so much?

I enabled debug logging mode, but I can't see exactly which new files it's transferring. Here's some of the log:
