Yeah, I have actually frozen Minio at this older version in my stack, as "just files on disk" was the primary feature that drew me to it. I don't want my data locked into some custom format. I'd be willing to bet that ZFS will still be supported in 20 years, but I would not make the same bet about Minio.
For the same reason, it looks like Garage is not an option for my use case.
Ah interesting. I found it appealing to always have a way to get at the data natively as a worst case for restores. The whole use case is for Vertical Backup (from the maker of Duplicacy) to back up VMs.
Minio _was_ just files on disk. They don't support that mode anymore since 2022-10-29 (see the big yellow warning box at [1]).
