Split/hybrid/isolated setup with two disks: Backup though contents of data folder have been moved?

Thanks. I need to consolidate all of this information in one post. I also calculated the break-event point in terms of “restores per year” for S3 GDA vs B2:

Do incremental off-site backups require to download previous backup(s)?

@alexweiss Note that he said: So the repository would not be directly accessed to take backups, which mitigates all of your concerns except cost. We can calculate which will be cheaper depending on how often you need to restore. Note that to keep this calculation simple, I am going to ignore the following: Per-request upload and download fees. Per-object GDA migration fees. S3 housekeeping object fees. S3 Standard storage fees both before transitioning to GDA and for restored objects held…

The summary is that if you perform a full restore approximately every two years, the cost is the same. If you restore less frequently, S3 GDA is cheaper. If you restore more frequently, B2 is cheaper.

I still prefer B2, even though I’ve never had to restore. There are no early deletion fees; all of the storage is “hot” so you don’t have to wait for a 5+ hour restore operation to access your data, and you can also prune regularly; and you can regularly run check operations if you want to. GDA is not so much cheaper that I am willing to trade all of that.
