Disaster Recovery: Restoration Staggering Helpful for Large Environments

Disaster Recovery: Restoration Staggering Helpful for Large Environments

When it comes to disaster recovery, large businesses have their own special challenges that don’t impact smaller enterprises in the same way or to the same extent. Several locations spread across a region, country, or content, a large workforce, and a wide variety of systems that need to get up and running quickly characterize large environments.

Restoration staggering refers to storing critical systems on separate servers and running their data backup and recovery at different times. Staggering during regularly scheduled backups and after a natural disaster, man made crisis, or technological catastrophe can make disaster recovery easier for enterprises operating in a large environment. It provides flexibility in sequencing, and reduces that strain on infrastructure that may be caused by moving large amounts of data at the same time and to the same location.

Separate Servers Reduce Risk of Data Loss

Separating and storing critical components on different servers ensures that a business doesn’t lose all of its critical data at once in the case of a disaster. Using a Storage Area Network, (SAN) or internet accessible cloud-based storage solution also lets you easily move files around between servers.

Staggered Backup Avoids Bottlenecks

Large enterprises can experience what are known as bottlenecks during regularly scheduled daily or weekly backups, because large amounts of data are being transferred all at the same time. Staggering backups puts less strain on infrastructure during regular backups because the process is spread across a wider network instead of all going to one server simultaneously.

Staggering Restoration to Avoid Bottlenecks During Disaster Recovery

Bottlenecks can become even more problematic during disaster recovery, because instead of just transferring the most recently required data, one or more entire systems have to be recovered and restored. This is particularly challenging for large environments, and can be alleviated by staggering restoration and recovery.

Staggering Storage Across Geographical Locations

Large enterprises may also enjoy the added benefit of having critical data stored on servers located in different geographical areas, particularly when large scale natural disasters like Superstorm Sandy occur.

If data can’t be recovered electronically and manual data retrieval is required, you may be able to have it couriered from the nearest data center outside of the area affected by the disaster.

Easier to Implement Prioritized Business Continuity Plan

As any business continuity planner worth her salt will tell you, getting your business operational again after a disaster benefits from a carefully crafted and well-tested prioritized disaster recovery plan.

A staggered recovery is useful for implementing a disaster recovery plan for large environments. Using a staggered system allows flexibility in retrieving, scheduling, and implementing the recovery and restoration of necessary components, because they are being retrieved from a variety of servers in different locations.The data is spread out, reducing the likelihood of being unable to access any of the information required, a situation which may occur when systems must be retrieved from just one location.

Instead, staggering recovery allows critical elements such as communications systems, to be restored quickly to help with the recovery and restoration of the lower priority components. .Businesses of all environment sizes and types should ensure they have access to a usable communication system as soon as possible after a disaster to contact employees, shareholders, and customers.
