I'm using ZFS on my desktop (Arch Linux). 1 'Pool' is just an SSD that my OS root drive. (Booting off ZFS is a bit harder but putting /boot on your ESP works).
And a hard disk array with 4 drives in raidz (like raid 5).
Main advantages:
* I moved my root drive to another drive and did it entirely online without needing to cp or dd everything just add new drive to pool, remove old drive (and wait until it's done, but you can keep using it while it copies)
* It's way faster than MD, md spends 10s of hours initializing or resilivering big drives. zfs just formats it and your good to go.
* Subvolumes and snapshops are great. You can give a folder different file system properties. (Eg make /var/log compressed and disable it for /var/cache/pacman because it's already compressed)
* Docker is quicker.
* Although BTRFS has snapshots I do find ZFS's more intuitive. (eg subvolume can be nomount in ZFS which allows you to organize and apply options recursively easier)
Check for bugs in Ubuntu ZFS before installing updating. They do it differently than other OpenZFS options.
I'm not currently using ZFS send for backups. So I can't compare it to Deja dup.
