+For recurring backup you can use CronJob, you don't need to run it in scheduled mode. as described bellow.

+# Migrate database
+
+To migrate the database, you need to add `migrate` command.
+
+{: .note }
+The Mysql backup has another great feature: migrating your database from a source database to a target.
+
+As you know, to restore a database from a source to a target database, you need 2 operations: which is to start by backing up the source database and then restoring the source backed database to the target database.
+Instead of proceeding like that, you can use the integrated feature `(migrate)`, which will help you migrate your database by doing only one operation.
+
+{: .warning }
+The `migrate` operation is irreversible, please backup your target database before this action.
