EBS Put Snapshot Block - BlinkOps 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. Data written to a snapshot must be aligned with 512-KiB sectors.

Basic Parameters

Parameter	Description
AWS Region(s)	Enter the desired AWS Region(s). To execute the action in multiple regions, provide a comma-separated list. For example: `us-east-1,eu-west-2`. If you wish to run the action in all available regions, use the asterisk symbol (`*`) instead.
Block Data	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.
Block Index	The block index of the block in which to write 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.
Checksum	A Base64-encoded SHA256 checksum of the data. Only SHA256 checksums are supported.
Checksum Algorithm	The algorithm used to generate the checksum. Currently, the only supported algorithm is `SHA256`.
Data Length	The size of the data to write to the block, in bytes. Currently, the only supported size is `524288` bytes. Valid values: `524288`.
Snapshot ID	The ID of the snapshot.

Advanced Parameters

Parameter	Description
Disable XML To JSON Auto Convert	When checked, XML responses are not automatically converted into JSON format.
Progress	The progress of the write process, as a percentage.
