Options

--snapshot-id (string)

The ID of the snapshot containing the block from which to get data.

Warning

If the specified snapshot is encrypted, you must have permission to use the KMS key that was used to encrypt the snapshot. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide .

--block-index (integer)

The block index of the block in which to read the data. A block index is a logical index in units of 512 KiB blocks. To identify the block index, divide the logical offset of the data in the logical volume by the block size (logical offset of data/524288 ). The logical offset of the data must be 512 KiB aligned.

--block-token (string)

The block token of the block from which to get data. You can obtain the BlockToken by running the ListChangedBlocks or ListSnapshotBlocks operations.

outfile (string) Filename where the content will be saved

Global Options

--debug (boolean)

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

DataLength -> (integer)

The size of the data in the block.

BlockData -> (streaming blob)

The data content of the block.

Checksum -> (string)

The checksum generated for the block, which is Base64 encoded.

ChecksumAlgorithm -> (string)

The algorithm used to generate the checksum for the block, such as SHA256.
