+# Backup

+Here's the command which should be tested and included in a /etc/cron.daily/dotclear2 script. Until Yunohost do allow user to manage backup through WebUI.

+    yunohost backup create --hooks dotclear2
+
+There might be two bugs preventing this command to work. First one

-Default YunoHost installation got a small bug that prevent `yunohost backup create`, here's the fix: `sed -i -e "302s/logging/logger/" /usr/lib/moulinette/yunohost/backup.py`
 
-Yet it doesn't seems to save apps, at least in my test environment. To be investigated.
