All shared hosting plans (including shared, business and reseller) plans are backed up nightly. However, these backups are not for individual use and only for recovery from any possible catastrophic event affecting the entire server. For these services, you would need to keep/maintain your own backups.
Cloud Server plans and Dedicated Server customers have the option of ordering a nightly backup addon package. Restoration is free for these backups.
For more information on our backups and what the backups include, please see our shared hosting backups guide.
