Hello,

Thank-you for your suggestions re. the partitioning of the USB in response to my previous email.

Note that I'm not especially concerned with restoring the USB exactly - with all its partitions, etc. It's a standard USB which was formatted on a windows machine to be a Live Fedora 32 stick. But prior to this I'd backed it up with duplicity simply by plugging into my Fedora machine when the weekly back-up was scheduled. It's true that even before it become the Live Fedora 32 stick,  it was a Live USB anyway. When I plugged it into the computer then I'd have a panel pop-up saying: 'Contains software. Would you like to run it?' But more importantly, there was data on it - in the data partition.

The restored USB could be reformatted to be a single large volume as has been suggested. I'm not clear if duplicity would only have backed-up the data partition on the USB (volume name '7160-75C1'). In a sense, it doesn't matter as the data is the part that matters and that remains in the archive which duplicity created. Does that all make sense?

This leads me to the use of duplicity. I notice a man entry for it here: https://linux.die.net/man/1/duplicity

duplicity restore [options] source_url target_directory

I couldn't understand how to use this command! My first unknown is the source URL. I'm using a external USB hardisk 'MyPassport' on /dev/sda1 for the duplicity archive.

Is it source file:///dev/sda1/Deja-Vu-Back-up where Deja-Vu-Back-up is the directory with the back-ups??

Somehow, I need to pass the name of the backed-up USB volume ('7160-75C1') too. Note that it's all the data contents of the the volume. Then there's the target directory too - anywhere in my hard disk in the home/user directory will do - on a standard Fedora setup.

Thanks for all your help and advice.

Thanks for this reply ... I should have said that the USB drive I mentioned (/run/media/awood/7160-75C1 ) was previously a bootable USB and partitioned as such. This leads me to wonder if I can simply rename the volume (is that the correct term?) to the previous name and then use Duplicity? But what's the parameters for a restore on this USB with this name?

Thanks for your help and assistance.

Andrew

You need to reformat it with the original filesystem id.  Open a

going to assume the drive is /dev/sdb and only has one partition.  Make 
sure it's unmounted by running:
umount /run/media/awood/Fedora-WS-Live-32-1-6
Don't click the eject button because that will also disconnect it from 
USB.  Then run "sudo mkfs.fat -i 716075C1 /dev/sdb1".  Replug the device 
and it should come up as before.
