CIM_StorageSynchronized class
Indicates that two Storage objects were replicated at the specified point in time. If the CopyType property is set to 'Sync' (=3), then synchronization of the Storage objects is preserved.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Qualifiers: Experimental
CopyMethodology specifies what copy methodology the service uses to create and/or maintain the target element.
Values are:

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.

CopyState
-
Data type: uint16
-
Access type: Read-only
-
Qualifiers: Experimental
CopyState 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 data flow has not started.
Unsynchronized: Not all the source element data has been copied to the target element.
Synchronized: For the Mirror, Snapshot, or Clone replication, the target represents a copy of the source.
Broken: The relationship is non-functional due to errors in the source, the target, the path between the two or space constraints.
Fractured: Target is split from the source.
Split: The target element was gracefully (or systematically) split from its source element -- consistency is guaranteed.
Inactive: Data flow has stopped, writes to source element will not be sent to target element.
Suspended: Data flow between the source and target elements has stopped. Writes to source element are held until the association is Resumed.
Failedover: Reads and writes to/from the target element. Source element is not reachable.
Prepared: Initialization is completed, the data flow has started, however, the data flow has not started.
Aborted: The copy operation is aborted with the Abort operation. Use the Resync Replica operation to restart the copy operation.
Skewed: The target has been modified and is no longer synchronized with the source element or the point-in-time view.
Mixed: Applies to the CopyState of GroupSynchronized. It indicates the StorageSynchronized associations of the elements in the groups have different CopyState values.
Partitioned: State of replication relationship can not be determined, for example, due to a connection problem.
Invalid: The array is unable to determine the state of the replication relationship, for example, after the connection is restored; however, either source or target elements have an unknown status.
This property is inherited from CIM_Synchronized.
