Creates, updates, deletes, gets or lists a changed_blocks resource.

Overview

Name	changed_blocks
Type	Resource
Id	aws.ebs.changed_blocks

Fields

The following fields are returned by SELECT queries:

list_changed_blocks

Name	Datatype	Description
block_size	integer	The size of the blocks in the snapshot, in bytes.
changed_blocks	array	An array of objects containing information about the changed blocks.
expiry_time	string (date-time)	The time when the BlockToken expires.
next_token	string	The token to use to retrieve the next page of results. This value is null when there are no more results to return. (pattern: <code>^[A-Za-z0-9+/=]+$</code>)
volume_size	integer (int64)	The size of the volume in GB.

Methods

The following methods are available for this resource:

Name	Accessible by	Required Params	Optional Params	Description
list_changed_blocks	select	second_snapshot_id, region	firstSnapshotId, pageToken, maxResults, startingBlockIndex	Returns information about the blocks that are different between two Amazon Elastic Block Store snapshots of the same volume/snapshot lineage. You should always retry requests that receive server (5xx) error responses, and ThrottlingException and RequestThrottledException client error responses. For more information see Error retries in the Amazon Elastic Compute Cloud User Guide.

Parameters

Parameters can be passed in the WHERE clause of a query. Check the Methods section to see which parameters are required or optional for each operation.

Name	Datatype	Description
region	string	AWS region (default: us-east-1)
second_snapshot_id	string	The ID of the second snapshot to use for the comparison. The SecondSnapshotId parameter must be specified with a FirstSnapshotID parameter; otherwise, an error occurs.
firstSnapshotId	string	The ID of the first snapshot to use for the comparison. The FirstSnapshotID parameter must be specified with a SecondSnapshotId parameter; otherwise, an error occurs.
maxResults	integer	The maximum number of blocks to be returned by the request. Even if additional blocks can be retrieved from the snapshot, the request can return less blocks than MaxResults or an empty array of blocks. To retrieve the next set of blocks from the snapshot, make another request with the returned NextToken value. The value of NextToken is null when there are no more blocks to return.
pageToken	string	The token to request the next page of results. If you specify NextToken, then StartingBlockIndex is ignored.
startingBlockIndex	integer	The block index from which the comparison should start. The list in the response will start from this block index or the next valid block index in the snapshots. If you specify NextToken, then StartingBlockIndex is ignored.
