| Name | Data Type | Value |
| CopyMethodology | uint16 | |
| Description | string | CopyMethodology specifies what copy methodology the service uses to create and/or maintain the target element.
Values are:
Not Specified: The method of maintaining the copy is not specified.
Full Copy: This indicates that a full copy of the source object is (or will be) generated .
Incremental-Copy: Only changed data from source element is copied to target element.
Differential-Copy: Only the new writes to source element are copied to the target element.
Copy-On-Write: Affected data is copied on the first write to the source or to the target elements.
Copy-On-Access: Affected data is copied on the first access to the source element.
Delta-Update: Difference based replication where after the initial copy, only updates to source are copied to target.
Snap-And-Clone: The service creates a snapshot of the source element first, then uses the the snapshot as the source of the copy operation to the target element. |

| CopyPriority | uint16 | |
| Description | string | CopyPriority allows the priority of background copy engine I/O to be managed relative to host I/O operations during a sequential background copy operation.
Values are: Low: copy engine I/O lower priority than host I/O. Same: copy engine I/O has the same priority as host I/O. High: copy engine I/O has higher priority than host I/O. Urgent: copy operation to be performed as soon as possible, regardless of the host I/O requests. |

| Write | boolean | true |
| CopyType | uint16 | |
| Description | string | CopyType describes the Replication Policy. Values are:
Async: create and maintain an asynchronous copy of the source.
Sync: create and maintain a synchronized copy of the source.
UnSyncAssoc: create an unsynchronized copy and maintain an association to the source.
UnSyncUnAssoc: create an unsynchronized copy with a temporary association that is deleted upon completion of the copy operation. |
| ValueMap | string | 2, 3, 4, 5, .., 0x8000.. |
| Values | string | Async, Sync, UnSyncAssoc, UnSyncUnAssoc, DMTF Reserved, Vendor Specific |
| ReadOnly | uint16 | |
| Description | string | This property specifies whether the source, the target, or both elements are "read only" to the host.SystemElement: The source element.
SyncedElement: The target element.
Both: Both the source and the target elements.are read only to the host. |
| Experimental | boolean | true |
| ValueMap | string | 2, 3, 4, .., 0x8000.. |
| Values | string | SystemElement, SyncedElement, Both, DMTF Reserved, Vendor Specific |
| ReplicaType | uint16 | |
| Description | string | ReplicaType provides information on how the Replica is being maintained. Values are:
Full Copy: This indicates that a full copy of the source object is (or will be) generated .
Before Delta: This indicates that the source object will be maintained as a delta data from the replica.
After Delta: This indicates that the replica will be maintained as delta data from the source object.
Log: This indicates that the replica object is being maintained as a log of changes to the source.
Not Specified: The method of maintaining the copy is not specified. |
| ValueMap | string | 0, 2, 3, 4, 5, .., 0x8000.. |
| Values | string | Not Specified, Full Copy, Before Delta, After Delta, Log, DMTF Reserved, Vendor Specific |
| SyncState | uint16 | |
| Description | string | SyncState describes the state of the association with respect to Replication activity. Values are:
Initialized: The link to enable replication is established.
and source/replica elements are associated, but the Copy engine has not started.
PrepareInProgress: Preparation for Replication is in progress and the Copy engine has started.
Prepared: All necessary preparation has completed.
ResyncInProgress: Synchronization or Resynchronization is in progress.
This may be the initial 'copy' or subsequent changes being copied.
Synchronized: An Async or Sync replication is currently synchronized. When this value is set, SyncMaintained will be true.
FractureInProgress: An operation to fracture an Async or Sync replication is in progress.
Fractured: An Async or Sync replication is fractured.
QuiesceInProgress: A quiesce operation is in progress.
Quiesced: The replication has been quiesced and is ready for a change.
RestoreInProgress: An operation is in progress to copy the Synced object to the System object.
Idle: The 'normal' state for an UnSyncAssoc replica.
Frozen: All blocks copied from source to an UnSyncAssoc replica and the copy engine is stopped.
CopyInProgress: A deferred background copy operation is in progress to copy the source to the replica target for an UnSyncAssoc association.
Broken: The relationship is non-functional due to errors in the source, the target, the path between the two or space constraints. |

| UndiscoveredElement | uint16 | |
| Description | string | This property specifies whether the source, the target, or both elements involved in a copy operation are undiscovered. An element is considered undiscovered if its object model is not known to the service performing the copy operation. The values are:
SystemElement: The source element.
SyncedElement: The target element.
Both: Both the source and the target elements. If both the source and the target elements are discovered, the value of this property shall be NULL. |
