in general I woud recommed to do your
"First steps with Relax-and-Recover"
on two virtual machines as described in
https://en.opensuse.org/SDB:Disaster_Recovery

On virtual machines trial and error attempts can be done easier,
faster, and less annoying compared to using real hardware
(in particular burning CDs again and again for each test).

Careful with external disks for the backup!
In the booted ReaR recovery system check before "rear recover"
what disk device node (e.g. /dev/sda versus /dev/sdb) is which
actual hardware to avoid that "rear recover" recreats the system
on your external disk which would overwrite your backup, see
https://github.com/rear/rear/issues/1271
and read about 'MIGRATION_MODE' in the current ReaR
GitHub master code in usr/share/rear/conf/default.conf
https://github.com/rear/rear/blob/master/usr/share/rear/conf/default.conf

In general when using USB you can have both the bootable ReaR
recovery system and the backup on the same external USB-disk.

See "Quick start guide" at
http://relax-and-recover.org/documentation/

When you use
------------------------------------------------------------
OUTPUT=USB
BACKUP=NETFS
BACKUP_URL=usb:///dev/disk/by-label/REAR-000
------------------------------------------------------------
I would also recommend to additionally set USB_SUFFIX
cf. usr/share/rear/conf/default.conf

For an advanced example that I used with "USB_SUFFIX"
you may have a look at
https://github.com/rear/rear/pull/1165
