ebs_put_snapshot_block | R Documentation |
Writes a block of data to a snapshot. If the specified block contains data, the existing data is overwritten. The target snapshot must be in the pending
state.

SnapshotId |
[required] The ID of the snapshot. 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.. |
BlockIndex |
[required] The block index of the block in which to write the data. A block index
is a logical index in units of |
BlockData |
[required] The data to write to the block. The block data is not signed as part of the Signature Version 4 signing process. As a result, you must generate and provide a Base64-encoded SHA256 checksum for the block data using the x-amz-Checksum header. Also, you must specify the checksum algorithm using the x-amz-Checksum-Algorithm header. The checksum that you provide is part of the Signature Version 4 signing process. It is validated against a checksum generated by Amazon EBS to ensure the validity and authenticity of the data. If the checksums do not correspond, the request fails. For more information, see Using checksums with the EBS direct APIs in the Amazon Elastic Compute Cloud User Guide. |
DataLength |
[required] The size of the data to write to the block, in bytes. Currently, the
only supported size is Valid values: |
Progress |
The progress of the write process, as a percentage. |
Checksum |
[required] A Base64-encoded SHA256 checksum of the data. Only SHA256 checksums are supported. |
ChecksumAlgorithm |
[required] The algorithm used to generate the checksum. Currently, the only
supported algorithm is |
