### 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.

#=================================================
# BACKUP THE APP MAIN DIR
#=================================================

ynh_backup --src_path="$final_path"

#=================================================
# BACKUP THE NGINX CONFIGURATION
#=================================================

ynh_backup --src_path="/etc/nginx/conf.d/$domain.d/$app.conf"

#=================================================
# BACKUP THE PHP-FPM CONFIGURATION
#=================================================

ynh_backup --src_path="/etc/php/$phpversion/fpm/pool.d/$app.conf"

#=================================================
# SPECIFIC BACKUP
#=================================================
# BACKUP THE MYSQL DATABASE
#=================================================
ynh_print_info --message="Backing up the MySQL database..."

### (However, things like MySQL dumps *do* take some time to run, though the
### copy of the generated dump to the archive still happens later)

ynh_mysql_dump_db --database="$db_name" > db.sql

#=================================================
# END OF SCRIPT
#=================================================

ynh_print_info --message="Backup script completed for $app. (YunoHost will then actually copy those files to the archive)."
