10 VM Replication Best Practices
Virtual machine replication (VM replication) is often confused with VM backup, but these VM data protection methods pursue different objectives and should not substitute each other (see our blog post VM Backup vs. VM Replication). A VM replica becomes a real lifesaver in case of disaster allowing you to perform VM recovery within seconds. Therefore, in recent years, VM replication has gained momentum in protecting virtual infrastructures from failures or downtimes of any origin. However, you may still experience difficulties and headaches while running VM replication software: app failures and errors, lost data, inadequately high consumption of resources, to say nothing of common troubles you may suffer from at the deployment, management, or maintenance stage. Fortunately, such complications can be avoided, and we strongly recommend that you follow the VM replication best practices listed below as part of your efficient VM data protection strategy.
1. Define Your Mission-Critical Data Areas and Establish Their Priorities.
Decide which of your virtual machine and application data require the highest protection and the fastest recovery in case of downtime or disaster. You do not need to replicate everything, and not everything needs to be recovered within the same time frame. For example, your online store maintains continuous operation and allows conducting direct order and purchase transactions with customers. In case your web server fails, the website, inventory, and CRM will be extremely critical to be recovered in the first place and as soon as possible to minimize the website downtime effect for customers, while, surely, back-office apps can wait.
