Description

The backup script uses RESTIC_HOSTNAME for deterministic hostname of the backup.

But restic itself already reads the env var RESTIC_HOST for the same purpose

RESTIC_HOST                         Only consider snapshots for this host / Set the hostname for the snapshot manually (replaces --host)

Contributor guide

Research direction
Locate all uses of RESTIC HOSTNAME in the backup script and replace them with RESTIC HOST, ensuring compatibility with restic's expected behavior.
