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.

Void Linux and root-on-ZFS question
Lastly there is zrepl. This is an automatic snapshot creation, pruning and replication daemon. It lets you automate the creation of ZFS snapshots at specific intervals, apply a retention policy to them, and replicate them out to a remote system with ZFS, like a NAS with TrueNAS on it.

How do you all prepare for a disaster recovery of your nextcloud instance?
I run it in a FreeBSD jail and take frequent ZFS snapshots using zrepl. I’ve had to restore after failed updates and it worked flawlessly.

Recommend ZFS automation scripts for off-server backups?
As others have noted, I use syncoid but zrepl is an alternative that could be considered.

Question about best way to do zfs replication to a friends server
Current idea: We offer some form of container each other, where we have that zvol mounted somewhere for the replication use. This would mean that I could create an "inside zfs" where I create a filebased zpool. How is performance on a filebased zpool? (Although it is technically not so important that it performs critically, just trying to find the - or one of - "best" ways). Then we would offer each an ssh endpoint into that container (It doesn't have to be ssh, but it is so far convenient to setup and resilient to be open to the public). And my current plan is to use zrepl (https://zrepl.github.io/) to organise replication from my home server to this "inside" zpool.

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.

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?
