I wouldn’t put my mission-critical file server on BTRFS.

Oh, but I and a lot of people do and it is way more reliable than ext* filesystems ever were. Maybe ZFS or XFS is more your style then? Ext4 is very, very prone to total failure and complete data loss at the slightest hardware issue. I’m not saying you should rely on any filesystem ever, backups are important and should be there, the thing it that recovering from backups takes time and the amount of recovery that ext forced me into over the years isn’t just acceptable.
