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

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

last sent snapshot?
You will probably need to list the destination snapshots and pick the last one in a shell script and if you are not game, you can use something simple like zfsbud to do the work for you.

Simple bash script for sending incremental snapshots daily
A simple bash-only alternative with a configuration file is zfsbud maintained by me.

Backup ZFS pool to remote system
I am responsible for zfsbud, feel free to let me know if you encounter any problems.
