John Paul Wohlscheid over at It's FOSS takes a look at the ZFS file system and its capabilities. He mainly covers OpenZFS which is the fork made since Oracle bought and shut down Solaris which was the original host of ZFS. It features pooled storage with RAID-like capabilities, copy-on-write with snapshots, data integrity verification and automatic repair, and it can handle files up to 16 exabytes in size, with file systems of up to 256 quadrillion zettabytes in size should you have enough electricity to pull that off. Because it started development under a deliberately incompatible license, ZFS cannot be directly integrated in Linux. However, several distros work around that and provide packages for it. It has been ported to FreeBSD since 2008.

    My evolutionary history of filesystem usage is remarkably similiar to yours. Arrived at ZFS around 2010/2011. Been using OmniOS as a storage backend for a couple years while my servers were ESXI-based. Now that I'm switching to Proxmox (OmniOS won't boot on KVM) I need to work around ZFS shortcomings on FreeBSD/FreeNAS, but it's still a winning team.

    The CIFS "time machine" functionality based on snapshots alone is worth it. AFAIK Linux can't do that yet, wake me when they're there :)

    For the time being, my Proxmox-based home server actually boots from a ZFSonLinux mirror, but my storage is on FreeNAS still. Moving company servers to Proxmox soon, even though FreeNAS' shortcomings with regards to snapshot staggering are putting me off.
