Phoronix: Btrfs Brings Some Great Performance Improvements With Linux 6.1

I always love pull requests that start off with "there's a bunch of performance improvements..." as is the case with the new Btrfs feature pull for Linux 6.1...

Good stuff

It’s good to see btrfs evolving into the FS it was originally promised to be. With ZFS never getting merged into the kernel I think it’s important that btrfs step up.

Personally I’d like to see someone implement an equivalent to Apple Time Machine using btrfs snapshots (maybe this already exists, I don’t know).

scottishduck Not familiar with Apple Time Machine, but is it maybe similar to Timeshift?

So some more performance improvements, some more fixes (raid5) and maybe, in ten year span, it would be usable as main fs?

Uh, about time for some new FS benches. I'm mostly interested in ext4, btrfs and f2fs.

Great.. I hope they'll merge the latest zstd too.

For the more command-line oriented people: that's what snapper does.
There are also plugins for some package manager, so you can get before/after snapshot whenever you update software, whith support for GRUB to boot into an older snapshot if anything goes wrong.
( e.g.: opensuse tumbleweed does that).

After playing around in the past with the timemachine backups of my father:
Yup Time Machine does basically what Timeshift's Rsync mode does, but with a few extra proprietary quirks.

For details and tools about these quirks, look here:

• https://github.com/torarnv/sparsebundlefs -- Apple uses multiple split image files to store the file system so the whole thing still works no matter what the external storage is -- e.g.: FAT32 formatted harddisk, Samba network share, etc -- and suports sparse mode.
• https://github.com/abique/tmfs -- in order to simplify storage: Apple use a modified HFS+ format that violates POSIX standards and actually allow directory hardlinking, so no need for deep subdirectories traversal on each backup, only when one of the sub-sub directory has changed content.
