Is it possible to restore single file or database from Plesk backup?
Starting from Plesk 12, users can select single objects to restore from a backup. This enables users to restore only what they need to restore, without overwriting other objects and risking damaging their configuration or data. For example, if a user wants to restore only a DNS zone of one domain, example.com, there is no need to restore configurations of all other domains.
It can be done at Home > Tools & Settings > Backup Manager:
Note: The restoration of selected objects is possible only from backups created in Plesk 12.0 or later.
