Btrfs ...
It's a good idea, and provided you don't do anything esoteric it's been
solid for years.
It used to have a terrible reputation for surviving a disk full - at a
guess it needs some disk space to shuffle its btree to recover space -
and a disk-full situation borked the garbage collection.
Raid-1 (mirroring) by default only mirrors the directories, the data
isn't mirrored so you can easily still lose that ... (they call that
user misconfiguration, I call it developer arrogance ...)
Parity raid is still borken...
At the end of the day, if you want to protect your data, DON'T rely on
the filesystem. There are far too many cases where the developers have
made decisions that protect the file system (and hence computer uptime)
at the expense of the data IN the filesystem. I don't give a monkeys if
the filesystem protects itself to enable a crashed computer to reboot
ten seconds faster, if the consequence of that change is my computer is
out of action for a day while I have to restore a backup to re-instate
the integrity of my data !!!
