Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

WinBtrfs โ an open-source btrfs driver for Windows
Heads up, installing both WinBTRFS and OpenZFS on Windows may have problems:
"Win OpenZFS driver and WinBtrfs driver dont play well with each other"

OpenZFS 2.2: Block Cloning, Linux Containers, BLAKE3
I tried it a few months ago and ReFS ate my data. No indication of why in event logs or SMART data. It had IsPowerProtected set because I have a UPS and I had a unclean restart, I would expect it to lose data, but not to corrupt the filesystem metadata. I had a backup of the data but wanted some recent changes. Refsutil (the official Microsoft tool) didn't help because it has not been updated for the newest ReFS version. I couldn't read most files because I had integrity enable and files failed the check. Hetman's Data Recovery was able to recover most of the data. In later testing I found out that IsPowerProtected is just very unsafe. I have since put some time into testing and sometimes fixing https://github.com/openzfsonwindows/openzfs , it is not ready for use yet, but it is making great progress.

Is there a mount backup vdev Windows tutorial
Windows lacks support in the same sense that Linux lacks support; there are external projects implementing it for both, though I believe the Windows port is less polished. (Some people are running it in production, though...)

Windows on Btrfs
This is really cool and speaks to the modularity of the Windows file system stack. I love projects that customize Windows (working against its closed-source nature).
Thereโs an OpenZFA port to Windows[0]. I wonder if my hopes of having ZFS on Windows (including the boot drive, because I would love to be able to snapshot and rollback) would actually be possible.

External Harddrive from NAS to Windows?
*cough* it can, but... no idea how well it works but it seems a bit hacky.

External Harddrive from Truenas to Windows?
If you have not used it, maybe the native ZFS port for windows could be an easier solution.

Problem with a NVMe device: it drops off the bus on intense IO, so I can't scrub or zfs send
Theoretically ZFS is ported to windows, but I heard that it is not really stable yet.

Is my open-source project up to date with MIT license compliance and attribution?
My projects and many projects include a THIRD-PARTY-LICENSES.html file when I distribute binaries. See: https://github.com/kimono-koans/httm/blob/master/third_party/LICENSES_THIRD_PARTY.html

ZFS and Proxmox Questions
The only real advantage I can think of with nested ZFS is that the files in the KVM would obviously be individual inodes in the nested ZFS filesystem and datasets, in addition to the one inode per virtual volume on the hypervisor (or zvol). This would allow for granular file management on the kvm and the use of tools like https://github.com/kimono-koans/httm which is like a command line time machine for ZFS.

ZFS silent corruption bug found: replaces chunks inside copied files by zeroes
> It's worth noting that copy_file_range is used by a lot of things.
Yes, but the trigger feature, block cloning, only landed in the latest 2.2 release. If you immediately hopped on 2.2, and used a system with lots copy_file_range and FICLONE use, yes, you may have a problem (like, as you note, on Gentoo, where this problem surfaced).
Most people were just hopping on the bandwagon. My distro ships 2.1.5, so I have a 6 month wait until this feature lands, so I was just building copy_file_range support into my ZFS apps, right before news of this bug hit.[0]
> There are other things required to trigger the bug that are a lot less common though.
Exactly. My guess is the incidence of this will exceedingly rare for the common user/small NAS user/etc. I've run a corruption detector[0], and what I've found mostly indicates false positives. Some are build artifact fingerprints, which I don't care about, and which were deleted with the next build. The ones with an extant file on another system, I confirmed were a diff match with the origin using `rsync -rincv` and whats on snapshots with `httm --map-aliases`. So far no positive matches.

Are you running Linux with a filesystem capable of block cloning/FICLONE (ZFS >= 2.2, XFS, BTRFS)?

Workflow: Rolling forward with ZFS and `httm`
httm prints the size, date and corresponding locations of available unique versions (deduplicated by modify time and size) of files residing on snapshots, but can also be used interactively to select and restore files, even snapshot mounts by file! httm might change the way you use snapshots (because ZFS/BTRFS/NILFS2 aren't designed for finding for unique file versions) or the Time Machine concept (because httm is very fast!).

Really no easy GUI Btrfs snapshots for Fedora 38?
All btrfs snapshot tools can have different layouts. It's mostly a nightmare for any one tool to support. Although its not the tool you're looking for, FYI AFAIK httm supports all/most btrfs layouts, but it took more work than necessary to get there.
- Why there is no tool that shows how file is changed over time across snapshots?
