***** Récupération d'un composant
Suivant si le type de backup est reconnu et le supporte, il est
possible de nommer un composant précis en lieu et place d'un
répertoire ou d'un fichier.
Par exemple, les backup de type 'mailcow' supportent les composants
suivants: =mailcow=, =postfix=, =rspamd=, =redis=, =crypt=, =vmail=,
=vmail-attachments=, =mysql=.
