Restore data backuped with Redo-backup

I made backup with app Redo backup (front end of partclone, http://redobackup.org/). But this application can't restore data on one partition, only on whole disks. I need find the way how to extract my backup on partition for data only, in my case /dev/sda8.

Backuped files:

Re-reading the partition table ...

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
