Many many years ago I set up btrfs for the disks I write my backups to with a raid 1 config for them. Unfortunately one of those disks went bad and ended up corrupting the whole array. Makes me wonder if I set it up correctly or not.
Nowadays, I have the following disks in my system set up as btrfs:
My backups disk because of compression.
My OS drive because of Timeshift.
My home folder because it feels safer. COW feels like it’ll handle power failures better, whilst there’s also checksumming so I can identify corrupted files.
My SSD Steam library over two drives because life is short and I cba managing the two ssds independently.
It’s going fine, but it feels like I need to manually run a balance every one in a while when the disk fills up.
I also like btrfs-assistant for managing the devices.
Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?
