No, I backup the production FreedomBox to just one internal machine.

It is possible that sshfs got disconnected, but I don't remember a
specific instance of power loss (both computers are on a UPS), freeze
requiring a power-off or any other circumstance that might have
disconnected it.  What I do remember is that there was a FreedomBox
upgrade and the reboot the next day at 2 am seems to have started the
problem.

Lots of possible solutions that people tried that ended up
not working in this report.

I ended up doing the following:

$ sudo ls -l /root/.cache/borg
total 4
drwx------ 1 root root  98 Oct 14 23:44 4390f79ac50d9366764cdfa98f3d0e03f9894049268e1ed1372b43d533d884f6
drwx------ 1 root root  98 Oct 15 13:23 4cd6fbbd74673977f062290b30109bead97deab4b0d08eca013b629f201c36b1
-rw------- 1 root root 198 Nov 16  2021 CACHEDIR.TAG

$ sudo rm -rf /root/.cache/borg/4390f79ac50d9366764cdfa98f3d0e03f9894049268e1ed1372b43d533d884f6
$ sudo rm -rf /root/.cache/borg/4cd6fbbd74673977f062290b30109bead97deab4b0d08eca013b629f201c36b1
$ sudo rm /root/.cache/borg/CACHEDIR.TAG

And then did a manual backup.  Still had the same problem.  Then, went
after the .config files, as suggested in the above link:

$ sudo rm -rf  /root/.config/borg/security/4390f79ac50d9366764cdfa98f3d0e03f9894049268e1ed1372b43d533d884f

$ sudo rm -rf  /root/.config/borg/security/4cd6fbbd74673977f062290b30109bead97deab4b0d08eca013b629f201c36b1

But that also didn't fix the issue.  A manual backup again caused the
same error 2 returned.

There is a yellow triangle and this in the backups page:

Command '['borg', 'list', '--json', '--format="{comment}"', '/media/054e54ca-da9c-11ec-abca-000db93f92a8']' returned non-zero exit status 2.

The latest error notification now goes to 158 attempts:

Error During Backup
A scheduled backup failed. Past 158 attempts for backup did not succeed. The latest error is: Command '['borg', 'list', '--json', '--format="{comment}"', '/media/054e54ca-da9c-11ec-abca-000db93f92a8']' returned non-zero exit status 2.

Any other ideas, anyone?

Thanks.
