Hello, What is the recommandation to backup globally an ISP Config server to be able to restore/clone the server completely (ISP settings + all domains and data) and reinstall it on a new physical server ? Best regards, Adam.
Clonezilla would work, https://clonezilla.org/ I would recommend ISPConfig migration toolkit, though: https://www.ispconfig.org/add-ons/ . If you already have a new physical server, migration toolkit would work in your case.
