# How to create a backup disk (for `soispha.services.backup`)

## Find the disk

```bash
lsblk -o "NAME,MAJ:MIN,RM,SIZE,RO,FSTYPE,MOUNTPOINT,UUID"
# or
sudo fdisk -l
```

## Check it

```bash
sudo smartctl --test=short /dev/disk
# or better:
sudo smartctl --test=long /dev/disk

# Run this to avoid a test timeout (otherwise the disk might go to sleep):
sudo watch --differences --interval 60 smartctl --log=selftest /dev/disk
```

## Add it

```
sudo mkfs.btrfs /dev/disk --label backup
```

And change the `backupUuid` to the uuid of the new disk.
