In DataLife Engine has an option to run some functions on a schedule. You can automatically generate a backup of the database to optimize database, and create a sitemap for search engines. Is required for this feature to your hosted application launch scheduled (CRON). To start the functions of the cron is cron.php file located in the root of your site. By default, for security reasons the setting to run this file is turned off, so if consider enable this feature, you can do so.

---

First, we recommend that for security reasons you should rename the file cron.php to something else but with extension .php

---

Next, open the file in a text editor and locate the very beginning of the line
    $allow_cron = 0;
Change it to
    $allow_cron = 1;
In this way you allow this file to perform the functions in automatic mode.

---

Then you can change the number of database backup files to be stored on the server. To do this, find below the line
    $max_count_files = 5;
Where 5 is the number of copies of the database. You can put your own number of files. If you exceed this limit, older backups of the database will be automatically deleted.

---

Now you need to add this file to run on a scheduled (CRON) the establishment and the frequency you set yourself. For detailed instructions on how to add the file in the CRON function you can get your hosting provider.
