Learn the basics of enterprise data recovery and find advice for choosing the best-fit data backup and recovery solution for your enterprise.
Enterprise data recovery is the process of restoring lost, corrupted, accidentally deleted, or otherwise inaccessible data to its server, computer, mobile device, or storage device (or to a new device if the original device no longer works).
Typically, the data is restored from a backup copy that is stored in another location. The more recent the backup copy, the more completely the data can be recovered in the event of loss or damage. For any business, successful data recovery—data recovery that prevents a greater-than-tolerable loss of data or discontinuity of business due to loss of data—requires the business to have a backup and restore plan that meets specific data recovery objectives, usually as part of a larger disaster recovery plan.
The term ‘data recovery’ can also refer to the following:
This article, however, will focus on enterprise data recovery.
Data loss due to human error remains more prevalent than data destruction due to natural or man-made disasters or criminal activities such as ransomware attacks. Your enterprise should, however, be prepared for any data loss that can disrupt critical business applications or operations, no matter what the cause.
A comprehensive backup and recovery solution should be in place to protect every piece of data worth saving, wherever it resides. Backups may cover the following:
In addition to files, there are certain of types of data you need to back up:
Once you determine the types of data you need to back up, you have to determine how frequently you need to back it up and how quickly you need to be able to restore it—that is, you’ll need to determine the recovery point objective and recovery time objective for each data set or related application.
Recovery point objective, or RPO, is essentially the age of the oldest backup you can tolerate. RPOs will vary depending on the data, the application, the industry, or a combination of these and other factors. For example, the email system at a coffee shop might be able to tolerate a 24-hour RPO, whereas the email system at a hospital, a bank, or some other highly regulated business may require RPOs measured in minutes. At a brokerage, where each trade could be worth millions, a trading system might have an RPO measured in seconds—or less.
Recovery time objective, or RTO, is the longest amount of downtime you can afford. The checkout at your local bookstore might have an RTO of hours or days, because downtime might cost USD 100 per hour. An online store might have an RTO measured in seconds, because each second of downtime might mean hundreds of thousands of dollars in lost business.
RPO and RTO will determine the frequency, method, and even the location of your backups. An application with an RPO and RTO measured in hours might be able to get by with nightly backups to any third-party cloud provider. An application with an RPO and RTO measured in seconds (or less) might require continuous data replication or even fully redundant systems hosted at a nearby location that can take over immediately and seamless in the event of any data loss or system problems.
Any data recovery service provider you work with should provide a service level agreement (SLA) detailing the RPOs and RTOs they are able to achieve, the security controls they have in place, and the safeguards against data loss they they’ve established. Your contract should specify the site or sites where your backups will be stored and should indicate how the provider will comply with any regulations in your industry.
Cloud backup and recovery solutions are increasingly popular among consumers and enterprises alike, but they’re especially useful when businesses have to back up large amounts of data (such as the contents of an entire data center) and want to reduce their infrastructure expense and administrative burden.
Cloud backup and recovery preserves copies of data in a secondary, offsite storage location. The cloud provider offers access to the storage—and, possibly, additional managed backup and recovery services—on a subscription basis with pricing based on storage volume and/or bandwidth usage.
The organization can select and deploy its own backup application, use one the cloud provider may offer, or employ a third-party service provider’s application. In all cases, the backup application designates files for backup, creates encrypted copies of the files, and sends them to the offsite backup destination.
Enterprises employing cloud-based backup and recovery solutions enjoy all the benefits cloud storage has to offer. The cloud provider assumes all responsibility for securing, managing, and maintaining the infrastructure, and will typically guarantee that you’ll have access to data whenever you need it. Storage capacities are highly elastic and can be scaled in accordance with demand, so you won’t pay for resources unless you need them.
The security of your data backups depends on two major things:
If your industry has regulations governing data privacy and security, you’ll want to make sure your backup tools, processes, or service providers comply with those regulations (if you work with a service provider, ask for certification of compliance). No matter what industry you’re in, you’ll want to pay particular attention to protecting any backups of data related to your intellectual property. And it’s important to ensure that any backups no longer needed are completely destroyed.
