AWS CLI for copying an older version of a file on s3

Question

I have a versioned bucket. I know that I can download older versions, but can I also copy with the aws command line interface (awscli) to s3 itself? Normally this would be something

aws s3 cp from-loc to-loc

Answer 1

From copy-object — AWS CLI Command Reference you can use:

aws s3api copy-object --bucket DESTINATION_BUCKET --key DESTINATION_FILENAME --copy-source 'SOURCE_BUCKET/SOURCE_FILENAME?versionId=VERSION_ID'

Note that the versionId is specified at the end of the --copy-source with: ?versionId=...

I tried it and it worked correctly:

$ aws s3api copy-object --bucket my_bucket --key version-output --copy-source 'my_bucket/IMG.jpg?versionId=OXxABkv6CbZ1TFY_oupeHRweEdBJa7_K'
{
    "CopySourceVersionId": "OXxABkv6CbZ1TFY_oupeHRweEdBJa7_K",
    "VersionId": "DJOCWGV79gq01WGVv4BIPIpfBDAPtYLI",
    "ServerSideEncryption": "AES256",
    "CopyObjectResult": {
        "ETag": "\"cf0accb1b590bc16f3806b270a03132d\"",
        "LastModified": "2023-06-06T08:13:50+00:00"
    }
}
