# S3 Replication

* You **must enable versioning in the source bucket and the destination bucket** otherwise Replication will not work.<br>
* The buckets used can be in different AWS accounts.<br>
* Can enable **Cross Region Replication (CRR)** or **Same Region Replication (SRR)**:\
  \
  \&#xNAN;**- CRR - Useful for lower latency access or replication across accounts.**\
  \
  \&#xNAN;**- SRR - Useful for live replication between production and test account.**<br>
