Backfilling snapshots from non-restic archives

I’m aware, that’s the whole point of this thread :smiley:

My goal with that illustration and this thread up to it was to find a potentially simpler approach than where #555 left off that would satisfy a large swath of migration use cases

For the usage of --path as I illustrated, could that be accomplished with only UI-level work on snapshot metadata and no changes to the snapshot process or data structure itself? Could you get behind such a solution or do you see deeper concerns still?
