Built stop the excellent SlateDB! Breaks files down into 256k chunks. Encrypted. Much much better posix compatibility than most FUSE alternatives. SlateDB has snapshots & clones, so that could be another great superpower of zerofs.

Incredible performance figures, rocketing to probably the best way to use object storage in an fs like way. There's a whole series of comparisons, & they probably need a logarithmic scale given the scale of the lead slatedb has! https://www.zerofs.net/zerofs-vs-juicefs

Speaks 9p, NFS, or NBD. Some great demos of ZFS with l2arc caches giving a near local performance while having s3 persistence.

Totally what I was thinking of when in the Immich someone mentioned wanting a way to run it on cheap object storage. https://news.ycombinator.com/item?id=45169036

The concept of "auto"-tiered, transparent storage is _really_ compelling! ...and the use of AGPL is really clever as an "enterprise poison pill".

It still sucks that S3 is ~$20/mo/TB basically "in perpetuity", while random SSD drives are ~$80/TB and I'd feel comfortable effectively amortizing them out at ~$20/yr for local storage instead of $20/mo for S3. :-/

ZeroFS will work with any S3 implementation that supports conditional writes. Even something a bit premium-priced like CloudFlare R2 goes for around $15/TB and has no egress costs. If you want to go for as cheap as possible, I'd throw minio or similar on a few cheap Hetzner storage servers https://www.hetzner.com/dedicated-rootserver/matrix-sx/

How does this compare to rclone, as I also asked in a top level comment? rclone can mount S3 as a union mount so it seems to have the same feature set? Have you benchmarked ZeroFS against rclone?

Unless I am missing something, rclone will probably compare similarly to https://www.zerofs.net/zerofs-vs-mountpoint-s3

		One big difference I see is that rclone is MIT licensed, whereas ZeroFS is licensed under AGPL with commercial license also available? https://www.zerofs.net/licensing
