How Incremental backup works? CWPpro

Hi,

For CWP pro users.

Is it just me or the incremental backup is just the same as full backup but uncompressed?

By definition: Incremental Backup
a security copy which contains only those files which have been altered since the last full backup.

But when I look at my backups, it's the whole account being backed up that is uncompressed.

Hello!

Yes, actually, this system should be improved.
