Hi @wizardfromoz ,What I'll do next is to show you how I have my Timeshift configured, with a view to your taking a full snapshot of your working distro to be stored to your 4TB drive.
As part of that, we may get you to take a leap of faith and blow away existing snapshots, and start the collection of them afresh.
Any such operations should be done when you are bright-eyed and bushy-tailed, ie not when you are about to catch zzzz's
Just read your above coming, in, noted.
Get a good night's sleep and I'll have more for you on your tomorrow.
I've already blown away all older snapshots and created a fresh one. I really love timeshift.
It has saved my butt a few times. I look forward to your new entry tomorrow morning my time.
