Thanks for the explanation. I was originally wondering if there was a way to ‘adopt the original backup set’ and effectively change the historical paths (similar to how Arq does it):
But, with your explanation, I understand that changing the historical backup directory path and hostname when moving the backup source to a new location is not important, they are certainly ‘as-was’ backups.
Also with de-duplication, restic should solve this nicely and it won’t be a space problem.
