I'm not clear on what you're asking here. Can you clarify your question? > What are the use cases which we need to set up collocated backup? How to set > it up? Colocated backups are useful when you want the performance benefits of load-balanced clustering as well as the data integrity enhancement of high-availability all using the same hardware. For example, if you had 2 physical servers and you wanted a load-balanced 2-node cluster then you would configure a clustered broker on each physical server. However, there is no high-availability or fail-over with this approach. Typically if you wanted to configure HA you'd add another 2 nodes to serve as backups for the current ones. However, using colocation the backup brokers can run in the same JVM as the live brokers.. For configuration information I suggest you consult the documentation [1] as well as the examples we ship with Artemis (specifically the "ha" examples).

This will allow instance#1 to get unprocessed messages from instance#2 when instance#2 has shut down, and vise versa. Normally when you set up data replication, you would set one instance as master, and another instance as slave. I am working on a project that needs me to set up HA for messaging with data replication, and it looks like I am running into issues with the normal setup. What is the deal of setting up colocated backup servers for data replication approach? What are the use cases which we need to set up collocated backup? How to set it up?
