### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
AutoDelete | boolean | false
Description | string | The created element can be deleted if system resources are running low.If TimeBeforeRemoval is specified, this property is ignored, even if it is set to true.
ModelCorrespondence | string | CIM_SynchronizationAspect.AutoDelete
Write | boolean | true
ConsistencyExempt | boolean | false
Description | string | If true, it indicates the new elements being added to a group of replication relationships -- for example, by the AddSyncPair operation -- do not participate in the consistency collection. Useful for a group of volumes belonging to an application, however, not all volumes of the application need to be part of the consistency set.
Write | boolean | true
ConsistentAsyncCopy | boolean | false
Description | string | If true, it indicates consistency to be requested for a single source and target volumes (not necessarily in replication groups). This is useful for implementations that use an intermediate snapshot of the source element, and then, asynchronously copy the data from the snapshot to the target element.
Write | boolean | true
ConsistentPointInTime | boolean | false
Description | string | This property applies to a group of elements. If it is true, it means the point-in-time to be created at an exact time with no I/O activities in such a way the data is consistent among all the elements of the group.
Write | boolean | true
CopyPriority | uint16 |
Description | string | This property sets the StorageSynchronized.CopyPriority property. CopyPriority allows the priority of background copy operation to be managed relative to host I/O operations during a sequential background copy operation. Values are: Low: copy operation lower priority than host I/O. Same: copy operation has the same priority as host I/O. High: copy operation has higher priority than host I/O. Urgent: copy operation to be performed.
ValueMap | string | 0, 1, 2, 3, 4, .., 0x8000..
Values | string | Not Managed, Low, Same, High, Urgent, DMTF Reserved, Vendor Specific
Write | boolean | true
CopyRecoveryMode | uint16 | 4
Description | string | If set to Automatic, the copy operation to continue after a broken link is restored. Automatic: copy operation to resume automatically. Manual: CopyState is to be set to Suspended after the link is restored. It is required to issue the Resume operation to continue. If not specified, the implementation decides.
ValueMap | string | 0, 2, 3, 4, .., 32768..65535
Values | string | Unknown, Automatic, Manual, Implementation decides, DMTF Reserved, Vendor Specific
Write | boolean | true
DeltaUpdateBlocks | uint64 |
Description | string | This property applies to Delta-Update copy methodology. If non-zero, it specifies the snapshots of source element should be created after this number of blocks have been modified. If both DeltaUpdateBlocks and DeltaUpdateInterval are specified the snapshot is created based on which criterion occurs first. If NULL or 0, the implementation decides the number of blocks.
Write | boolean | true
DeltaUpdateInterval | datetime |
Description | string | This property applies to Delta-Update copy methodology. It specifies the interval between the snapshots of source element, for example, every 23 minutes will have the value of 00000000002300.000000:000, using the CIM interval format. If NULL or 0, the implementation decides the interval.
Write | boolean | true
DesiredCopyMethodology | uint16 |
Description | string | Control what copy methodology the service should use. For the most part, the service decides the best methodology based on the SyncType. However, an implementation may allow the client to suggest a different methodology. Full-Copy: The entire source data is copied to target. 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 snapshot as the source of the copy operation to the target element. Copy-before-Activation: Start copying data in the background before activation. Redirect-On-Write: New writes to source or target elements are redirected to new locations and only metadata is updated to point to new data location.
ValueMap | string | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, .., 0x8000..
Values | string | Other, Instrumentation decides, Full-Copy, Incremental-Copy, Differential-Copy, Copy-On-Write, Copy-On-Access, Delta-Update, Snap-And-Clone, Copy-before-Activation, Redirect-On-Write, DMTF Reserved, Vendor Specific
Write | boolean | true
DesiredRPO | datetime |
Description | string | Recovery Point Objective indicates the maximum interval in which data might be lost. For synchronous copy operations, RPO is 0. For asynchronous copy operations RPO represents the interval since the most recent transmission of data to the target element. For example, to indicate 15 seconds, the value would be 00000000000015.000000:000, using the CIM interval format. If NULL, the implementation decides the interval if RPO is applicable.
