An incremental backup contains only runtime artifacts of each managed virtual machine in the service instance.
Note:
All incremental backups are automated scheduled backups. You cannot create an incremental backup on demand.
While creating an incremental backup, Oracle SOA Cloud Service promotes the backup to a full backup if any of the following conditions are met:
The configuration data of the service instance has been restored since the last scheduled full backup.
The service instance has been scaled out since the last scheduled full backup.
Oracle SOA Cloud Service can now reach a virtual machine that it could not reach during the last scheduled full backup.
The last full scheduled backup is no longer available.
You can recognize a promoted backup in the list of available backups from its type and creation time. Any full, automated backup created at the scheduled time for an incremental backup has been promoted.
