Previously you could only configure a single daily backup of a site’s files and/or database. Now customers can define up to four daily, four weekly, and four monthly site backups.
You can define the time you’d like each daily backup to run, the day of the week and time of day for each weekly backup, and the day of the month and time of day for each monthly backup. You can also choose to delete the backups after a certain number of days for daily, weekly, and monthly. And you can choose to backup the database or files or both for daily, weekly, and monthly.
For more details check out the Site Backups doc.
