     - **Replica managed disks (if your source VM uses managed disks)**: Site Recovery creates new replica managed disks in the target region to mirror the source VM's managed disks of the same storage type (standard or premium) as the source VM's managed disks.
     - **Cache storage accounts**: Site Recovery needs an extra storage account called *cache storage* in the source region. All the changes on the source VMs are tracked and sent to the cache storage account. They're then replicated to the target location.
     - **Availability set**: By default, Site Recovery creates a new availability set in the target region. The name has the "asr" suffix. If an availability set that was created by Site Recovery already exists, it's reused.
-    - **Disk encryption sets (DES)**: Site Recovery needs the disk encryption set(s) to be used for replica and target managed disks. You must pre-create DES in the target subscription and the target region prior to enabling the replication. By default, a DES is not selected. You must click on ‘Customize’ to choose a DES per source disk.

     - **Replication policy**: Defines the settings for recovery point retention history and app-consistent snapshot frequency. By default, Site Recovery creates a new replication policy with default settings of *24 hours* for recovery point retention and *60 minutes* for app-consistent snapshot frequency.
