Marco,

The replication *inside* Swift is not intended to move data between two 
different Swift instances -- it's an internal data repair and rebalance 
mechanism.

However, there is a different mechanism, called container-to-container 
synchronization that might be what you are looking for. It will sync two 
containers in different swift instances. The swift instances may be in 
different Keystone administrative domains -- the authentication is not based on 
Keystone. It does require that each swift instance be configured to "recognise" 
each other. However, this is only usable for low update rates.

Regards,
Donagh

Subject: [openstack-dev] [swift] Replication multi cloud

Hi all,

we would use the replication mechanism in swift to replicate the data in two 
swift instances deployed in different clouds with different keystones and 
administrative domains.

Is this possible with the current replication facilities or they should stay in 
the same cloud sharing the keystone?

Cheers,
Marco
