I have scheduled full backups on my all virtual server which backups are FTP to my local computer. The backup is creating a domainname.tar.gz file for each server. These are running wihout problems. The backups are FULL backups.

But when I extraced a tar file i can see many folders (numbered folders) . Its something looks like folders for an Incremental backup. Each folders has different files!

Any Idea what the problem here??
Many Thanks
