Hi Vijaya, We need to do some homework on 'Veeam Backup & replication software to replicate the Virtual machine' issue; we don't know how they work. However we can share the situation what our other customers are using for their mission critical system. - They are using Gluu cluster setup. One of them has three cluster ( 2 Dev clustered, 2 QA clustered and 2 Prod clustered ). - They are taking two snapshots on daily basis; full VM backup snapshot; one at 12 PM and another one at 12 AM. - As they are cluster so there is load balancer there for sure. - As far as I have heard, they are planning to put another standalone server in cloud ( those Dev,QA and Prod clusters are inside of their own vm farm ). - If there is any problem in any server or if we need to work in any production machine; we can keep that specific machine out of LB pool. In that way, end users never face any outage.

Thank you for the quick response, I am attaching some notes at the end here to give you a quick overview of how the veeam replication works, The replication job takes point-in-time copy of a VM including its configuration, OS, applications, associated data, system state and so on. we were able to successfully test the replication on our critical systems like Public Web, Oracle , Learning Management system and so on. We will consider the cluster and the option of having second instance in Cloud using Global load balancer ( GSLB), Does Gluu service depends on the IP Address ? In case there is change in IP of IDP & Active directory at the DR Site, does it require additional configuration before we start services. We may require your assistance in testing when we simulate this testing. Thanks Best Regards, Vijay Kumar ---- Veeam provides us exact copy of your virtual machine (VM) in a ready-to-start state as on specifc time of schedule, the replication job creates an exact copy of the VM in the native VMware vSphere format on a spare host, and maintains this copy in sync with the original VM. Veeam Backup & Replication does not install agent software inside the VM guest OS to retrieve VM data. To replicate VMs, it leverages VMware vSphere snapshot capabilities. When you replicate a VM, Veeam Backup & Replication requests VMware vSphere to create a VM snapshot. The VM snapshot can be thought of as a cohesive point-in-time copy of a VM including its configuration, OS, applications, associated data, system state and so on. Veeam Backup & Replication uses this point-in-time copy as a source of data for replication. In many respects, replication works similarly to forward incremental backup. During the first replication cycle, Veeam Backup & Replication copies data of the original VM running on the source host, and creates its full replica on the target host. Unlike backup files, replica virtual disks are stored uncompressed in their native format. All subsequent replication cycles are incremental. Veeam Backup & Replication copies only those data blocks that have changed since the last replication job session. To keep track of changed data blocks, Veeam Backup & Replication uses different approaches.

Veeam backup looks good as they are using the base of vSphere snapshot. But please make sure that how much resources they require inside a VM; we might need to additional CPU and memory to allocate those services along with Gluu components. >> Does Gluu service depends on the IP Address ? In case there is change in IP of IDP & Active directory at the DR Site, does it require additional configuration before we start services. Yes, Gluu Server highly depends on IP address. If IP changes; there might be up to 2 working days configuration required.

Thank you for the prompt response, we will ensure the additional CPU and memory is provided. last question, does it really require 2 working days to change the configuration our RTPO is between 24-48 hours and we would like to bring the services sooner if possible. Thanks

>> does it really require 2 working days to change the configuration our RTPO is between 24-48 hours and we would like to bring the services sooner if possible Up to 2 working days, yes. That means, don't change the IP address. :-) Even if something really bad happens and there is no way to recover server other than changing IP address... then we are here.

That's fine, you may go ahead and close the case. appreciate your prompt response Zico. Have a good day. Best Regards, Vijay Kumar
