Prepare and prevent: Virtual recovery and backup strategies

It's important to be proactive against virtual disasters, but when they happen, it's important to be prepared with backup and recovery strategies that will minimize downtime.

Introduction

Backup and recovery are two of the most pressing issues for virtual servers. If you plan to prevent downtime and have a virtual recovery plan in place when it does happen, you're going to be ahead of the game. When an issue arises, there is almost a guarantee of prolonged downtime unless you're prepared.

One of the best ways to deal with an issue is to be proactive and try to prevent it. Choosing the proper level of high availability, as well as developing a disaster avoidance plan, are just two steps to take to actively prevent a disaster.

If something does happen, it's also important to have a virtual recovery plan. Developing disaster recovery strategies might seem unimportant when you haven't experienced an issue, but having a plan will go a long way in minimizing downtime when a problem does occur.

1High Availability-

Designing a high availability and disaster avoidance plan

If you're worried about how you'll cope with a virtual disaster, you should first focus on preventing it before it actually strikes. Developing a disaster avoidance plan will be key to help your business avoid prolonged downtime. Another way to prevent a disaster is by designing a proper high availability architecture. These prevention steps will help before you get to your virtual recovery plan.

3Snapshots-

Using snapshots as part of your virtual recovery and backup plan

One popular method that should be a part of your virtual recovery plan to prevent downtime is using snapshots. Snapshots can help you quickly roll a VM back to a previous state to prevent prolonged downtime if a configuration change causes unexpected problems. Unfortunately, snapshots don't always work as expected. Here are some guidelines that can help you decide how often to take snapshots and how to troubleshoot when one fails.
