Automatic container snapshots? cv4pve or zfs for a small homelab?
From my research, I can see two options: - Proxmox specific cv4pve-autosnap - generic zfs-auto-snapshot, available in repos
-
Some Proxmox Backup, Snapshot and Storage questions
Since Proxmox natively supports ZFS, you could that to make your snapshots. You can do automatic snapshots with zfs-auto-snapshot or for VMs with cv4pve-autosnap.

zfs hourly snapshot - snapshot naming interpretation needed
If you're using zfs-auto-snapshot (and it looks like you are), note that the timestamps are always in UTC, not your local timezone. Is your timezone somewhere around UTC-12:00?

How to use Cron command to create zfs snapshots every hour with naming the time?
You may want to skip trying to manage these manually and use something like this: https://github.com/zfsonlinux/zfs-auto-snapshot

$ rm Important.txt (uh oh)
Not every operation, but it's easily automated. https://github.com/zfsonlinux/zfs-auto-snapshot

Maybe a very uncommon use for sanoid: setup for snapshots 2 daily
zfs-auto-snapshot is as simple as it comes. It has cron jobs that show you how to take periodic snapshots. It cleans up its old versions.

Snapshots and replication with zfs hold and zfs release
Another option to look at (again, 3rd part stuff, not vanilla zfs hold/release stuff) is zfs-auto-snapshot which takes (and retains) n snapshots based on how you run it. See: https://github.com/zfsonlinux/zfs-auto-snapshot

Radxa's SATA HAT makes compact Pi 5 NAS
> The only non-junk PCIe3 option that's even advertised here recently is the overpriced WD Red SN700.
Those WD drives seem to have some real issues, at least with ZFS and btrfs. :(

DiskClick: Ever wanted to hear Old Hard drive sounds
IMO the "next fs" is just zfs. They somewhat recently merged RAIDZ expansion feature https://github.com/openzfs/zfs/pull/12225 and make regular improvements. If no file system has what you need today, zfs will probably be the first one to have it "tomorrow," imo.

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.

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.

Why does primarycache=metadata reduce my un-cached read speeds?
Difference may be significant, yes https://github.com/openzfs/zfs/pull/14243
What are some alternatives?
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.)
zstd - Zstandard - Fast real-time compression algorithm
zfs_autobackup - ZFS autobackup is used to periodicly backup ZFS filesystems to other locations. Easy to use and very reliable.
7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard
zfsbud - ZFS snapshotting, replicating & backup rotating convenience bash script
zfsnap - A portable, performant script to make rolling ZFS snapshots easy. (https://github.com/zfsnap/zfsnap/issues/109)
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
znapzend - zfs backup with remote capabilities and mbuffer integration.
snapper - Manage filesystem snapshots and allow undo of system modifications
zfs-scripts
zfsbootmenu - ZFS Bootloader for root-on-ZFS systems with support for snapshots and native full disk encryption
