Bcachefs snapshots

Bcachefs is not just targeted at caching - it’s meant to be a superior replacement for ext4, xfs and btrfs. We intend to deliver a copy on write filesystem, with all the features you’d expect from a modern copy on write filesystem - but with the performance and robustness to be a very viable replacement for ext4 and xfs. Never know ya IBM is the monkey wrench. They could decide paying for ZFS is less hassel. But Red Hat has been defaulting XFS for RHEL server for 3 years now... and the continue unlining XFS improvements. They as far as I know are still following their XFS roadmap... An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bac...

Nov 26, 2019 · A versioning file system is any computer file system which allows a computer file to exist in several versions at the same time. Thus it is a form of revision control. Most common versioning file systems keep a number of old copies of the file. Some limit the number of changes per minute or per hour Edit: It appears that the trick I mentioned could also be done with bcachefs (using the dm-snapshot trick), but I noe that the filesystem in question is not yet in the mainline Linux kernel.

Bcachefs got * compression * Snapshots * cow * checksumming * in build caching He checks his code against the xfs test suite so hopefully it really will be stable and useable. My main problems with bcachefs are: Btrfs vs lvm Btrfs vs lvm ZFS features go well beyond the data checksumming and self-healing capabilities; it's powerful snapshots are much better than LVM snapshots and it's inline lz4 compression can actually improve performance by reducing disk writes.
