Offsite Retention
You can configure retention for your replicated backup data. The terms backup and backup copy are completely different. A backup copy “copies” the restore point of the backup data (VM) from the source backup server to the Offsite DR Server. The reason why the restore point is copied is, during the restore you can roll back to any of these restore points.
You can configure retention for image-based backups and for application backups. Enable the Image Retention Status option and configure the daily merged recovery points from the Keep daily merged recovery points drop-down list. Similarly, for application backups, you can retain versions for the replicated data from the File & Application Retention Status.
