Fields
kind

string

[Output Only] Type of the resource. Always compute#snapshot for Snapshot resources.
id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.
creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.
name

string

Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
description

string

An optional description of this resource. Provide this property when you create the resource.
status

enum

[Output Only] The status of the snapshot. This can be CREATING, DELETING, FAILED, READY, or UPLOADING.
sourceDisk

string

The source disk used to create this snapshot.
sourceDiskId

string

[Output Only] The ID value of the disk used to create this snapshot. This value may be used to determine whether the snapshot was taken from the current or a previous instance of a given disk name.
diskSizeGb

string (int64 format)

[Output Only] Size of the source disk, specified in GB.
storageBytes

string (int64 format)

[Output Only] A size of the storage used by the snapshot. As snapshots share storage, this number is expected to change with snapshot creation/deletion.
storageBytesStatus

enum

[Output Only] An indicator whether storageBytes is in a stable state or it is being adjusted as a result of shared storage reallocation. This status can either be UPDATING, meaning the size of the snapshot is being updated, or UP_TO_DATE, meaning the size of the snapshot is up-to-date.
licenses[]

string

[Output Only] A list of public visible licenses that apply to this snapshot. This can be because the original image had licenses attached (such as a Windows image).
snapshotEncryptionKey

object

Encrypts the snapshot using a customer-supplied encryption key.

After you encrypt a snapshot using a customer-supplied key, you must provide the same key if you use the snapshot later. For example, you must provide the encryption key when you create a disk from the encrypted snapshot in a future request.

Customer-supplied encryption keys do not protect access to metadata of the snapshot.

If you do not provide an encryption key when creating the snapshot, then the snapshot will be encrypted using an automatically generated key and you do not need to provide a key to use the snapshot later.
snapshotEncryptionKey.rawKey

string

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource. You can provide either the rawKey or the rsaEncryptedKey. For example: 

"rawKey": "SGVsbG8gZnJvbSBHb29nbGUgQ2xvdWQgUGxhdGZvcm0="

snapshotEncryptionKey.rsaEncryptedKey

string

Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource. You can provide either the rawKey or the rsaEncryptedKey. For example: 

"rsaEncryptedKey": "ieCx/NcW06PcT7Ep1X6LUTc/hLvUDYyzSZPPVCVPTVEohpeHASqC8uw5TzyO9U+Fka9JFH z0mBibXUInrC/jEk014kCK/NPjYgEMOyssZ4ZINPKxlUh2zn1bV+MCaTICrdmuSBTWlUUiFoD D6PYznLwh8ZNdaheCeZ8ewEXgFQ8V+sDroLaN3Xs3MDTXQEMMoNUXMCZEIpg9Vtp9x2oe=="
The key must meet the following requirements before you can provide it to Compute Engine:
  1. The key is wrapped using a RSA public key certificate provided by Google.
  2. After being wrapped, the key must be encoded in RFC 4648 base64 encoding.
Gets the RSA public key certificate provided by Google at:
