Bucket Replication to multiple destinations

ObjectScale supports replication to multiple destinations. The limitation is that there cannot be more than one destination bucket in the same object store within a single replication policy.

Shown below is a simple example of an XML document for a bucket replication policy with multiple destinations:

<?xml version="1.0" encoding="UTF-8"?>
<ReplicationConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <Role>arn:aws:iam::AcctID:role/jimmy</Role>
  <Rule>
    <ID>rule1</ID>
    <Priority>1</Priority>
    <Filter><Prefix>foo</Prefix></Filter>
    <Destination><Bucket>arn:aws:s3:US-E:foo:bucket1</Bucket></Destination>
    <DeleteMarkerReplication>
      <Status>Disabled</Status>
    </DeleteMarkerReplication>
  </Rule>
  <Rule>
    <ID>rule2</ID>
    <Priority>2</Priority>
    <Filter><Prefix>food</Prefix></Filter>
    <Destination>
      <Bucket>arn:aws:s3:US-E:foo:bucket1</Bucket>
      <StorageClass>MCFREEZE</StorageClass>
    </Destination>
    <DeleteMarkerReplication>
      <Status>Disabled</Status>
    </DeleteMarkerReplication>
  </Rule>
  <Rule>
    <ID>rule3</ID>
    <Priority>3</Priority>
    <Filter><Prefix>foodo</Prefix></Filter>
    <Destination><Bucket>arn:aws:s3:US-W:foo:bucket2</Bucket></Destination>
    <DeleteMarkerReplication>
      <Status>Disabled</Status>
    </DeleteMarkerReplication>
  </Rule>
</ReplicationConfiguration>

In the following example policy, there are two different destination buckets. The name of the object determines the destination bucket that the object is replicated to and the parameters for that replication.


Object Name	Rules Matched	Destination Buckets	Other Behavior
bar	none	no replication	none
foo	rule1	bucket1	none
food	rule1, rule2	bucket1	The storage class of the object in bucket1 will be set to MCFREEZE because rule2 has the highest priority of all the rules that matched for destination "bucket1".
foodo	rule1, rule2, rule3	bucket1 & bucket2	The storage class of the object in bucket1 will be set to MCFREEZE because rule2 has the highest priority of all the rules that matched for destination "bucket1". The storage class of the object in bucket2 will still be the bucket's default storage class.
