Hi Garrit,
Thanks for sharing your setup. I am currently in a similar journey and
evaluating different options.
My main concern with this setup is the extensibility aspect, If I need to
add more storage space in the future.
I was considering btrfs in raid 5 mode but it seems like it's not super
stable yet.
I am also considering the use of backblaze for offside backup. I had an
excellent experience with them so far.
This, brings me to the encryption configuration. I assume you are using
dmcrypt in both locations? Another option would be restic for offsite so
you don't have to worry about unlocking the remote disk if system reboots.
A final consideration with this is about monitor the health of your disks.
I wonder what solution you opted for (chat bot / gotify + script that
checks SMART metrics?)
Sorry for the long comment =F0=9F=98=85
I just loved your post and wanted to share some thoughts/questions.
Kind regards,
Amine

I've been very impressed by how well Btrfs handles extensibility. I have
recently thrown new drive at my setup. The main advantage of Btrfs in my
opinion is that you can combine any drives you want, as opposed to ZFS,
where you're more or less constrained to drives of the same size.
Regarding RAID: You're right, RAID 5 is unfortunately still unstable.
After one year, I don't regret going with RAID 1 (mirrored) for my
setup. If you have 4+ drives, I suggest you take a look at RAID 10,
since it gives you some advantages over RAID 1.

Great choice! Backblaze has been rock solid for me as well. And they're
cheap too!

This is a topic I haven't dipped my toes into yet. All of my drives are
unencrypted. Thanks for your recommendations though, I will have to look
those up! Are you using restic in your current setup?

Some time ago I wrote up a blog post about using healthchecks.io with
docker:
https://garrit.xyz/posts/2021-05-15-healthchecks-io-with-docker
healthchecks.io is really neat, since *you're* responsible of pinging
their endpoints, as opposed to *them* pinging a HTTP-endpoint. This
enables you to write Cron-scripts that frequently check the health of
your drives. I'm currently using this script to check my drives:
```
#!/bin/bash
curl -fsS -m 10 --retry 5 -o /dev/null $PING_URL/start
output=$(btrfs scrub start -B /var/anubis)
curl -fsS -m 10 --retry 5 --data-raw "$output" -o /dev/null $PING_URL/$?
```
maybe it's of use for you?
Thanks again for your comment!
Best
Garrit
