Just try, on the Pi:
wget https://raw.githubusercontent.com/graham8/osmc-backup/refs/heads/master/osmc-restore
@grahamh OK, I’ll remember that for next time 
Today I just copied it out of your git site and pasted it into the nano editor.
It ran with no errors however I had to do it without the -f option as it would still not complete because of the issue with the second partition.. There must be something special with that particular SDCard?
But, all did work correctly with the original version and a different SDCard…RDK
