Three Levels of Data Loss and the Disaster Recovery Steps Applicable to Each

Data loss is a serious problem for businesses of all sizes and even “minor data loss can result in lost hours, missed opportunities, and lost revenue”. The fact remains that every business has the potential for data loss. Data loss can occur for various reasons including but not limited to data being deleted accidently or data becoming corrupted as a result of viruses, physical damage, or formatting errors.

You can, however, limit the consequences of potential data loss by understanding the three levels of data loss and the disaster recovery steps to take when each occurs.

Application issues or minor data loss

The first level of data loss refers to application issues or minor data loss that can occur. Minor data loss can include a file or directory accidently being deleted.

What should I do?

Isolate: Identify the source and disconnect from the network.

Identify: Identify all encrypted files and time frame of infection.

Recover: Recover all encrypted files and systems.

Primary infrastructure

This second level of data loss can include losing primary storage, losing a switch or firewall, a breakdown in internet connectivity or losing public cloud or data center power. I can also include failed data, application, or datacenter migration.

What should I do?

Identify: Locate your most recent backup.

Rebuild: Rebuild or restore your systems, applications, and data.

Restore to Service Level Agreement: Storing backups on disk outside of your primary infrastructure is critical to preventing large scale corruption.

The "crater"

As the name suggests, the data loss associate with “the crater” is the most severe and usually associated with a form of complete and permanent destruction. These include permanent damage (fire, water, etc.), denial of access, an act of God (weather/nature) and the destruction of infrastructure.

What should I do?

Declare: Invoke your Disaster Recovery/Business Continuity Plan.

Setup: Establish your new location.

Restore: Restore all of your applications, systems and data.

It is clear from the three levels of data loss and the disaster recovery techniques applicable to each, that it is essential to have an effective disaster recovery plan. Our next post will outline how to develop an effective disaster recovery plan.
