guix system: fout: beschadigde invoer tijdens het terugplaatsen van het 
archief uit #<closed: file 7f8ffe7977e0>

Problems:
  * The server not having a file is not an exceptional situation;
    it should just skip this server or just report that there
    is no available location for this resource instead of
    a backtrace.

  * It claims ‘corrupt input while restoring ...’, but it isn't
    corrupt -- non-existence is not a form of corruption.

  * ‘1.46Gi’ should be ‘1.46GiB’ or ‘1.46GiB/s’ -- Gi is just a prefix,
    it's missing a unit.

In case it matters, I have

          (build-accounts 40)
          (extra-options '("--gc-keep-derivations" "--gc-keep-outputs" 
"--max-jobs=14"))

in the system configuration.

Greetings,
Maxime.
