The StorageGRID CloudMirror replication service enables a tenant to automatically replicate objects to an external S3 bucket. You can enable replication using the Tenant Manager.
CloudMirror replication copies objects from a source bucket to a destination bucket that is specified in an endpoint. To enable CloudMirror replication for a bucket, you must create and apply valid bucket replication configuration XML. The replication configuration XML must use the URN of an S3 bucket endpoint for each destination.
For general information on bucket replication and how to configure it, see the Amazon documentation on cross-region replication (CRR). For information on how StorageGRID implements the S3 bucket replication configuration API, see the instructions for implementing S3 client applications.
If you enable CloudMirror replication on a bucket that contains objects, new objects added to the bucket are replicated, but the existing objects in the bucket are not. You must update existing objects to trigger replication.
If you specify a storage class in the replication configuration XML, StorageGRID uses that class when performing operations against the destination S3 endpoint. The destination endpoint must also support the specified storage class. Be sure to follow any recommendations provided by the destination system vendor.
