Backup and DR Converge in an 'Instant'
Data protection has evolved at such a rapid pace over the last few years that today's backup and disaster recovery systems barely resemble those from a decade ago. One of the ways this evolution has occurred is through the convergence of backup and disaster recovery and the emergence of instant recovery.
In the past, data backup and DR were primarily treated separately. Backup was about making a recoverable copy of data or entire servers, while DR was concerned with continuity of business -- the idea of moving workloads to new hardware and remote locations in the event of a major disaster.
A great deal of the convergence can be attributed to server virtualization. Most organizations are heavily virtualized, and server virtualization provides a degree of flexibility that simply was not possible until somewhat recently. Not only does the hypervisor deliver new capabilities, but many backup vendors have design features that exploit the portability of virtual machines.
The convergence of backup and disaster recovery technologies, and the rise of instant recovery, has occurred largely because snapshot, replication and virtualization have made it possible to recover from a disaster without the need for a traditional data restoration. The methods involved in this convergence seek to minimize storage cost, while also allowing for instant recovery.
In this e-book chapter, explore these methods and how the convergence of backup and disaster recovery and emergence of instant recovery could apply to your organization.
