Your Backups page lists every backup of your sites. How often backups run and how long they are kept depends on your plan and backup add-on.
Download a backup
Choose Download next to a backup. You get one .tar file with the complete backup: website files, databases, mail and settings. Keep it as an offsite copy, or upload it to any Plesk server.
Restore a backup
Choose Restore next to a backup. Your site is replaced with that backup, usually within a few minutes. Anything changed since the backup was made is lost, so download a fresh copy first if you might need it.
Delete a backup
Choose Delete. It is removed permanently.
