PageBlobClient.GetManagedDiskPageRangesDiffAsync Method

Definition

The GetManagedDiskPageRangesDiffAsync(Nullable<HttpRange>, String, Uri, PageBlobRequestConditions, CancellationToken) operation returns the list of page ranges that differ between a previousSnapshotUri and this page blob. Changed pages include both updated and cleared pages. This API only works with managed disk storage accounts.

For more information, see Get Page Ranges.

Parameters

range
Nullable<HttpRange>

Optionally specifies the range of bytes over which to list ranges, inclusively. If omitted, then all ranges for the blob are returned.

snapshot
String

Optionally specifies the blob snapshot to retrieve page ranges information from. For more information on working with blob snapshots, Create a snapshot of a blob.

previousSnapshotUri
Uri

This parameter only works with managed disk storage accounts. Specifies that the response will contain only pages that were changed between target blob and previous snapshot. Changed pages include both updated and cleared pages. The target blob may be a snapshot, as long as the snapshot specified by previousSnapshotUri is the older of the two.

conditions
PageBlobRequestConditions

Optional PageBlobRequestConditions to add conditions on getting page ranges for the this blob.

cancellationToken
CancellationToken

Optional CancellationToken to propagate notifications that the operation should be cancelled.

Returns

A Response<T> describing the valid page ranges for this blob.

Remarks

A RequestFailedException will be thrown if a failure occurs.
