I faced a similar problem several times. Even yesterday, about the same story. Until I understood tightly ...

I dont understand what you understand tightly?
Let's say you going to backup folder which is 10 GB.
If you do Incremental backup, so first backup will be full with 10GB, next one incremental should small with only changes were made and so on... but in my situation it is doing full every day. and my disk fulfilled in a week.
So where I made mistake?

An interesting question. Dear Hermes101, do a FULL BACKUP. Maybe files have been added to the source folder since the creation of the FULL BACKUP? This is an option.

Interesting. Clear archive attribute is checked. Is Use archive attribute also checked on the General table?

Check user's privelegies. User has to be permitted to set additional attributes. Cobian Backup does not check that archive attribute has been removed successfully, and do not show any notifications about this issue.

PS sorry for my english :)

Actually it shows those errors as well but you need to change the log type to Verbose. It will slow down your backup a bit though.
