Bcachefs – A New COW Filesystem

• httm

  98 1,199 9.9 Rust

  Interactive, file-level Time Machine-like tool for ZFS/btrfs/nilfs2 (and even actual Time Machine backups!)

Really excited about this.

Once support hits in Linux, a little app of mine[0] will support block cloning for its "roll forward" operation, where all previous snapshots are preserved, but a particular snapshot is rolled forward to the live dataset. Right now, data is simply diff copied in chunks. When this support hits, there will be no need to copy. Previous snapshot blocks can just be used as refs.

> That's not a reasonable standard for reviewers.

It is when the attitude is "What's the big deal?" ZFS is two decades on, and, is by many metrics, still the state of the art in the traditional filesystem space. What ZFS does is extremely hard, and the reason we know is because every open source competitor can't touch it, so I'm saying -- have a little respect.

You don't like it? You prioritize reflinks (ZFS just merged block cloing BTW: https://github.com/openzfs/zfs/pull/13392) or offline dedup over RAIDZ? Fine. But make sure your favorite filesystem can do what ZFS does before you throw that shade.

Not exactly ZFS in Rust, but more like a replacement for ZFS in Rust: https://github.com/redox-os/tfs

Worked stalled, though. Not compatible, but I was working on overlayfs for freebsd in rust, and it was not pleasant at all. Can't imagine making an entire "real" file system in Rust.
