The Plesk backup/restore utilities allow backing up the Plesk server configuration information as well as its current content (client accounts, domains and so on) as they are at a certain moment in time - the moment when the backup is carried out. They also allow restoring these data on the server. This proves useful when either you need to execute a system operation, which can influence such data (for instance, upgrade the OS that Plesk is running on), or simply for safety purposes. The two utilities that provide these functions are: Plesk Backup and Plesk Restore.
