S3 CRR and objects locks


A customer is building a DR architecture, using S3 CRR to copy its data to another region. All the infra is replicated (at small scale) in the DR region.

The source S3 bucket is accessed by a SFTP server doing read/write operations. So there is another SFTP server in the DR region, pointing to the CRR bucket, ready to take over if DR occurs.


Is there any kind of locking on the CRR done by the CRR process, preventing access from the DR SFTP server to the CRR bucket ?

The S3 Consistency model applies, with no object locks between writes. See more details here: https://docs.aws.amazon.com/AmazonS3/latest/dev/Introduction.html#ConsistencyModel.
