My backups failed. Don’t panic!
Both of my Western Digital backup disks decided to break a few months back. Fortunately I also backup on the cloud, so could recover much of what was lost.
Except for my collection of films and TV shows purchased on Apple iTunes over the years. Now lost after a region changed rendered them ‘unavailable in your location’.
I sometimes wonder what archeologists three or four thousand years from now will think of our society when it’s been lost to endless upgrades, tech glitches and takeovers.
