zrepl: A one-stop, integrated solution for ZFS replication
I have rather nice experience with ZnapZend https://www.znapzend.org/
Only issue i've found is the fact there is no official Debian repository and i always do forget to recompile it after upgrading Debian :-D
I really like the configuration system integrated in ZFS set/get...

ZFS or BTRFS for raid0 + backup server
Hi, I'm using zfs on my home server since years. (Proxmox host). Never had any problems, I'm using https://www.znapzend.org/ for automatic snapshot which are cheap (time and required space) and they get synced with my backup server.

znapzend VS zfs_autobackup - a user suggested alternative

Docker volume backup
If you need something that’s more for peace of mind than for rigorous backup policy, you could use the ZFS storage driver, and do periodic snapshots of the whole tree, or use some shell scripting to enumerate the volumes you care about and zfs snapshot or zfs send them somewhere safe.

How to setup znapzend with local backup on OpenIndiana
The official documentation is overly complicated for this purpose. A simple example config is:
-
Are child datasets mounted recursively when the parent is mounted?
OK question time! I have znapzend configured via znapzendzetup. Now need to set up a matching OpenIndiana service as described here.

How do I ensure that I do not get a time-delayed ransomware attack?
The method I use is to run scorch every night to compute hashes for new files and check around 12% of old files for hash errors every night. Even if your backup is the same day as a ransomware attack, you will still catch it if the attack hits enough files for one to get randomly scrubbed. Also scorch is designed around making the hash database small and independent from the rest of the system, so you can automate copying it to a bunch of different places.

ZFS or BTRFS for raid0 + backup server
Lastly, you could just point scorch (https://github.com/trapexit/scorch) at your drives and run it on a cron or systemd timer - just have the script alert you with an e-mail or whatever your preferred method is. Not ideal but probably less work than rebuilding two arrays because you don't like the format of error messages.

Embarking on my hoarding journey
If you really care, you can use something like scorch or file-digests to get the hashes of your files and just store that in a text file, recalculating monthly. No need to get fancy with it. Hell, write your own simple script that hashes, outputs to file, and checks previous versions.
