I've been running a RAID-1 btrfs data store for about 10 years. In
that time, I've hit one bug that required me to restore from
backup. That was 9 years ago, when the FS was about as stable as an MP
in a three-way marginal constituency.
I'm now up to 11TB of data on a 13TB RAID-1, and it's been fine for
years, even over power failures and several disk failures.
That sounds good, I'll get it set up and migrate the data across. :-)
The primary things you need to ensure is that your
hardware is
reliable (no USB storage, and disks and controllers which honour flush
instructions), <snip>
Thanks for the tips.
Scrub regularly, avoid compression and qgroups and
parity RAID for
metadata, and you should be fine.
Note that RAID-1 is *not* a backup. You still need backups.

I'm very good about preaching about backups, not so great at actually
doing them myself. My longer-term intention is to set up an off-site
daily-updated backup server, probably at my parents rather than in the
cloud, but I don't have the money for that currently.
Thanks
