I used the terminal command as suggested...and to my surprise Timeshift still operated...clicked on its link and it still showed its main windows.....
So...I accessed it via synaptic and marked it for complete removal. That stopped the link operating.
Then, accessed /var/log/timeshift, and opened it as root....and deleted it....same for /etc/timeshift.json
Then accessed the snapshot folder on the seagate 1TB, opened it as root, and right clicked and selected delete for both snapshots. This process too approx 15 minutes to finish
I rebooted....Reinstalled Timeshift from Software manager
Followed t he 'wizard' through...set the 1TB as the Location and Rsync etc etc....set my desired schedule....I only keep 2 daily snapshots and the on demand snapshots.....
Created an on demand snapshot
I will observe tomorrow morning to ensure that the desired schedule is adhered to, and thats that !!!
Gotta go....drive my girl to Deepwater
