Whether as a Service or On Your Own, You Need a Disaster Recovery Solution
With all the talk about backup as a service (BaaS) and disaster recovery as a service (DRaaS), it’s easy to assume you need cloud as your backup and disaster recovery solution. It’s true that in many cases, cloud provides a good solution: simple, automated, and cost effective. However, if you don’t want to use cloud, it’s still possible to roll your own effective disaster recovery solution.
Reasons Not to Use Backup and Disaster Recovery Services in the Cloud
When making any decision, technical or otherwise, it’s important to have a substantial reason that supports the decision. What are some of the reasons you might not want to rely on DRaaS?
- Cloud can go down. Cloud isn’t infallible. Even the major cloud providers have experienced significant outages that have prevented cloud users from accessing their data. If a cloud outage coincides with your own outage, you won’t be able to access the data you need to recover.
- Security considerations. By now, almost everyone acknowledges that the risks to data in cloud have been overstated, especially when compared to the risks of data on premises where good security practices may not be enforced. Nevertheless, it remains true that when you store data in the cloud, it is potentially accessible by individuals who aren’t associated with your business.
- Cost. As with other cloud services, you’ll pay for what you use with backup and disaster recovery in the cloud. It’s important to note that while clouds don’t charge for uploading data to the cloud, they do charge for pulling data back out of the cloud. Before you commit to a cloud service, understand whether charges will apply to accessing backed up data and how much a disaster recovery will actually cost you.
Implementing Your Own Disaster Recovery Solution
If you decide not to rely on BaaS and DRaaS, you’ll want to make sure your homegrown solution provides the protection you need.
Backups underpin any disaster recovery strategy, so start with an effective backup policy. Best practice is to adhere to the 3/2/1 rule: have at least 3 copies of your data (including production), on 2 different types of media, with at least 1 copy off site.
You’ll need a site to recover to when your primary production site is down. You can use cloud for this or an offsite secondary location. If you don’t use cloud, you’ll need to equip it with a mirror of your primary location’s equipment. This can be expensive, though you generally won’t want to duplicate test and development servers.
Because you’ll be executing your disaster recovery process without help from a provider, having a detailed disaster recovery plan is even more important. The plan should contain the detailed steps to recover each workload and should be guided by their recovery time and recovery point objectives. It’s vital to test your disaster recovery plan at least annually to make sure it is complete and correct and can be executed within the necessary timeframes.
