I use this on all my Pis.

Interesting take. I would have gone for “A known enemy of Putin suddenly dies in a plane crash over Russian airspace.”

I did have a problem with this, but it was due to a password manager (possibly Chrome’s built-in one which I had a load of passwords duplicated in at one point) auto-filling a hidden field with the wrong password.

The front-end error is backup corrupt, but it’s not, it’s just the encryption key has been changed at the point of restore. Sort that and error gone.

Backing up to a local server and then shunting off to B2 is largely what I do, except I just use a local file share and try not to store much locally. The Windows 10 built in backup works quite well for this. The file share I back up using Duplicati.

They finally worked out how to exit this realm?

I have a Backblaze B2 account I use for other things, I recently created a new bucket on it and attached it as a drive using s3fs. Works fine as far as I can tell (I’ve not used it much - prefer to keep things locally and just back them up off-site, which is actually what I have my B2 account for), so you certainly can do this with an S3 (AWS) compatible service.
