If using Dell Data Protection backup appliances such as the DL1x00 or DL4x00 series, the target Core to
which you replicate must have a valid software license configured. These hardware appliances include a
replication target license with purchase. Check for your license key in the welcome email message you
received when purchased the appliance. For assistance, visit the Licensing Assistance website at
support.software.dell.com/licensing-assistance

Recovery point chains and orphans
Rapid Recovery captures snapshots of a protected machine, and saves the data to a repository as a recovery
point. The first recovery point saved to the Core is called a base image. The base image includes the operating
system, applications, and settings for each volume you choose to protect, as well as all data on those volumes.
Successive backups are incremental snapshots, which consist only of data changed on the protected volumes
since the last backup. The base image plus all incremental snapshots together form a complete recovery point
chain.
From a complete recovery point chain, you can restore data with ease and confidence, using the full range of
recovery options available to Rapid Recovery. These options include file-level restore, volume-level restore, and
bare metal restore.
Since logically you cannot restore from data that does not exist, in the case of an incomplete recovery point chain,
you cannot restore data at the volume level or perform a bare metal restore. In such cases, you can still restore
any data that does exist in a recovery point at the file level.
If the information you want to restore from a recovery point is in a previous backup that is not available to the
Core (an earlier incremental snapshot or the base image), the recovery point is said to be orphaned. Orphaned
recovery points are typical in some replication scenarios.
