The Backup process is fine for me:
Backup file is created in documents/admin/backup
Download links are available.
The Restore process I find poor.
Currently it gives only a description of how to do it using the command line or doing it my phpmyadmin.
I would have expected it to list the files in documents/admin/backup so you can select one to restore.
Is there any reason it cannot be like this/is open to changes?
