> - If you are thinking of ZFS/TrueNAS because of the scrubbing functionality, RAID1 + BTRFS also have scrubbing.

In my experience, BTRFS is to be avoided. It's the only FS that I've lost data to.

Same here, so I had to overcome this fear. But to be fair, my incident was >10 years back, and I was trying to be fancy (resizing a live FS - IIRC). Btrfs has gone a long way since then, and is even the standard filesystem for Synology NAS boxes.

Same here, repeatedly. I've never had a BTRFS fs that didn't spontaneously combust before it would have been decommissioned. Recovery or even check is always impossible. Only things that have caused more loss were (old) XFS on Linux that ate files every power outage and ReiserFS which also blew up in an unfixable way. I'll always recommend staying away from them. A filesystem should always have reliability and no loss, particularly no invisible loss, as its top priority.

I have one btrfs going at the moment. Nothing important, naturally. Just a Silverblue test installation. Will see how that fares.
