### N.B. : the following 'ynh_backup' calls are only a *declaration* of what needs
### to be backuped and not an actual copy of any file. The actual backup that
### creates and fill the archive with the files happens in the core after this
### script is called. Hence ynh_backups calls takes basically 0 seconds to run.
