A data corruption bug in OpenZFS?
https://github.com/openzfs/zfs/issues/15526#issuecomment-181...
> zpool get all tank | grep bclone
> kc3000 bcloneused 442M
> kc3000 bclonesaved 1.42G
> kc3000 bcloneratio 4.30x
> My understanding is this: If the result is 0 for both bcloneused and bclonesaved then it's safe to say that you don't have silent corruption.
It's a very rare race condition, odds are very low that you were impacted. If you were, you would have noticed (heavy builds with files being moved around where suddenly files are zero).

Ask HN: What's your "it's not stupid if it works" story?
A couple years ago, I had an idea for convincing a filesystem to go faster using 2 compression steps instead of one. I couldn't see why it wouldn't work, and I also couldn't convince myself it should.
It seems to have worked out. [1]

ZFS Profiling on Arch Linux
https://github.com/openzfs/zfs/issues/7631
This is a long-standing issue with zvols which affects overall system stability, and has no real solution as of yet.
More details on this discussion: https://github.com/openzfs/zfs/issues/6824#issuecomment-1817... . Basically he is too busy to continue developing the encryption features but is able to review the related works.
There is also discussion about using ZFS on LUKS in the same thread: https://github.com/openzfs/zfs/issues/6824#issuecomment-1819...
ZFS on top of LUKS seems to have it's own issues though. :(

Tell HN: ZFS silent data corruption bugfix – my research results
https://github.com/openzfs/zfs/pull/15529#pullrequestreview-...
Honestly, ZFS is the best thing on the (Free)BSDs only... On Linux it doesn't even use the page cache, and you conflict severely with L2ARC. I know there's a variety of people who don't care, but still for real users it's not an actual option.

In OpenZFS and Btrfs, everyone was just guessing
A more "correct" fix has been posted https://github.com/openzfs/zfs/pull/15615
Current Master: https://github.com/openzfs/zfs/blob/acb33ee1c169bf1c1f687db1...
When I look up the problem, I could only see the issue being discussed, and probably leading to that commit, and then it was not in my current release (2.1) despite several years later. I’m wondering if ZFS still holds that high standard for reliability.

Incremental backups / replication to non-ZFS destinations?
Z3 doesn't seem to be maintained. This script seems to be a oneoff. ZFSBackup Go seems more full featured but also unmaintained and out of date as well.

Welcome Z3 – ZFS to S3 Backup/Restore Tool
To add, i'm not so confident in future usability given it's python 2[0].
What are some alternatives?
zstd - Zstandard - Fast real-time compression algorithm
7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
sanoid - These are policy-driven snapshot management and replication tools which use OpenZFS for underlying next-gen storage. (Btrfs support plans are shelved unless and until btrfs becomes reliable.)
snapper - Manage filesystem snapshots and allow undo of system modifications
zfsbootmenu - ZFS Bootloader for root-on-ZFS systems with support for snapshots and native full disk encryption
zrepl - One-stop ZFS backup & replication solution
centos-stream
systemd - The systemd System and Service Manager
Netdata - The open-source observability platform everyone needs
zyggy - ZFS Administration GUI
