Data backup clean-up

How can i clean up previous data backup results and begin backup from scratch?

NethServer Version: 7.3.1611
Module: Backup

Just mount the the backup dir:

rm -rf /mnt/backup/<your_machine_name>

But I still see a tree of previously saved folders in web-interface in the section ‘Restore files’.
How to remove it?

Cleanup cache dir:

rm -rf /var/cache/restore/*

Thanks. All worked.
