This is Blog 3 of 5 on Zerto Replication. This blog will cover how to create Virtual Protection Groups (VPG). A VPG is a group of VMs that need to be grouped together for replication purposes. An example would be an application server and a database server. A more specific example would be an instance like Microsoft Exchange. Typically you have 2 to 3 servers for Exchange (Database, Software and Web) and they need to be in sync at all times.
What you need to have in place before you Create a VPG
- ZVM at both sites
- The sites paired
- VRAs deployed at both sites
- VPGs already planned out
1. Login to Zerto. Every tab in Zerto has the “New VPG” option at the top right. Select New VPG
2. There are several setting that you need to set here. First off you want to name the VPG
- Target Site – The site you are replicating to
- Host – The Host you want the VMs in the VPG to reside on. You also have the option of selecting a cluster
- Datastore – Target Datastore for the replicated VMs
- Failover Move Network – The network you want the VMs to use in the event of a failover
- Failover Test Network – The network you want the VMs to use when test your VPGs. The idea is to be able to bring up the replicated VMs in a “Test bubble” or isolated VLAN so that there is no production issues during testing.
- Folder – The organizational folder you want the VMs to be in
- Priority (QOS) – The priority of the VPG
- Target RPO Alert – The maximum time between each automatic checkpoint being written to the journal before an alert is issued.
- Default Journal History – The time for which all write commands are saved in the journal
- Test Frequency Reminder – How often you want to test your VPG. If you don’t reach that time period you will get an alert
- Wan Compression
There is also an option for recovery scripts at the bottom
3. After all that is completed then you can add your VMs to the VPG
After your VPG is complete you can select it and monitor the progress of the initial Sync and review the mapping of resources to DR. Overall a simple process.
The next blog will discuss Testing a VPG as well as a VPG failover
