post_archive_retry_script
:   Hook script launched after a WAL file is archived by maintenance.
    Being this a _retry_ hook script, Barman will retry the execution of the
    script until this either returns a SUCCESS (0), an ABORT_CONTINUE (62) or
    an ABORT_STOP (63) code. In a post archive scenario, ABORT_STOP
    has currently the same effects as ABORT_CONTINUE. Global/Server.
