instantSnapshots.export the changed blocks between two instant snapshots to a customer's bucket in the user specified format.
HTTP request
POST https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instantSnapshots/{instantSnapshot}/export
The URL uses gRPC Transcoding syntax.
Path parameters
| Parameters | |
|---|---|
project |
Project ID for this request. |
zone |
The name of the zone for this request. |
instantSnapshot |
Name of the instant snapshot to export. |
Query parameters
| Parameters | |
|---|---|
requestId |
An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( |
Request body
The request body contains data with the following structure:

Response body
If successful, the response body contains data with the following structure:
Represents an Operation resource.
Google Compute Engine has three Operation resources:
You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.
Operations can be global, regional or zonal.
- For global operations, use the
globalOperationsresource. - For regional operations, use the
regionOperationsresource. - For zonal operations, use the
zonalOperationsresource.
For more information, read Global, Regional, and Zonal Resources.

| Fields | |
|---|---|
kind |
[Output Only] Type of the resource. Always |
id |
[Output Only] The unique identifier for the operation. This identifier is defined by the server. |
creationTimestamp |
[Deprecated] This field is deprecated. |
name |
[Output Only] Name of the operation. |
zone |
[Output Only] The URL of the zone where the operation resides. Only applicable when performing per-zone operations. |
clientOperationId |
[Output Only] The value of |
operationType |
[Output Only] The type of operation, such as |
targetLink |
[Output Only] The URL of the resource that the operation modifies. For operations related to creating a snapshot, this points to the persistent disk that the snapshot was created from. |
targetId |
[Output Only] The unique target ID, which identifies a specific incarnation of the target resource. |
status |
[Output Only] The status of the operation, which can be one of the following: |
statusMessage |
[Output Only] An optional textual description of the current status of the operation. |
user |
[Output Only] User who requested the operation, for example: |
progress |
[Output Only] An optional progress indicator that ranges from 0 to 100. There is no requirement that this be linear or support any granularity of operations. This should not be used to guess when the operation will be complete. This number should monotonically increase as the operation progresses. |
insertTime |
[Output Only] The time that this operation was requested. This value is in RFC3339 text format. |
startTime |
[Output Only] The time that this operation was started by the server. This value is in RFC3339 text format. |
endTime |
[Output Only] The time that this operation was completed. This value is in RFC3339 text format. |

The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of |
error.errors[].errorDetails[].errorInfo.domain |
The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com". |
error.errors[].errorDetails[].errorInfo.metadatas |
Additional structured details about this error. Keys should match /[a-zA-Z0-9-_]/ and be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than {"instanceLimit": "100/request"}, should be returned as, {"instanceLimitPerRequest": "100"}, if the client exceeds the number of instances that can be created in a single (batch) request. |
