hmmm I am unable to reproduce this locally - is there a step there that i might be missing?

I used a legacy backup - restored it in a selectable profile with replace - repeated that replace - and then turned on backup.

Could you try changing the backup location and doing a backup? Does the make it work?

Same error if changing the location see video.

I am unable to reproduce, but given that this only occurs upon recovering the same backup twice (likely only on the same machine), it's not a very likely scenario. Marking as P3/S3!
