On the back server the data copied to the backup space ist compared each day to the previous day's backup. If there are any changes found, a copy of the data will be made (a snapshot taken). Thus the user has access to 7 daily, 4 weekly and 3 monthly backups. During each snapshot, only the modified data is copied - thereby making optimal use of the available disk space.
This OpenLDAP related section of the Backup service is described on the [[stoney backup: OpenLDAPdirectory data organisation]] page.
