Automatic Backups are done using JetBackup which utilizes an incremental backup system.
You may restore any backup using your cPanel->JetBackup->Restore Backups
Note: Backup feature depends on the plan you choose. It is also important to always have a personal-local backup of your website to avoid data lose. JDCHost is not liable for any data lose due to web server crash, loss of backup and other incident.
