I would like to point You to little problem of use colon in backup script - “/var/ipfire/backup/bin/backup.pl” - on line 22
NOW="$(date “+%Y-%m-%d-%H:%M”)"
when used with external programs to copy (manage) backup files - they will convert to “%3A” (WinSCP for Windows in My case) and this is not good looking therefore I would recomend usage of “_” character instead of “:”.
