files are not archived
No file *.rar or *.zip
the files are unpacked

My settings:

“Archive” just means that backup will not be deleted while they are still marked as archived. It does not mean that they are zipped or rar’d. They are just protected from deletion by the system.

I would like the option to back up over the week, month, year …
Very necessary, saving disk space.
