IT Solutions: Adopting an ‘Instant Recovery’ Model
According to recent industry surveys, the average small or medium-sized business is already backing up its data. A backup alone, however, is not a complete solution to disaster recovery -- the backup system must be able to restore the data back into needed locations so work can resume. A key variable in the recovery process is the amount of time that is needed for the restore process itself. If the time needed is too long, the impact of data loss can be significant even if the data is eventually recovered.
‘Instant Recovery’ is now Possible
With virtualization, the time-to-recovery variable can be greatly reduced or even largely eliminated. This approach is known as ‘instant recovery’. To adopt this model, businesses need to organize their virtual infrastructure so that they are always in a state conducive to fast recovery. This generally requires the business to be running parallel servers so that if and when the primary server fails, a virtual one can immediately step in and take the steps necessary to bring programs and other needed computing elements back online.
Although the term ‘instant recovery state’ is used to describe this process, in general the implementation of such a scheme takes a few minutes from start to finish. Once the virtual server has accomplished this, the system can be run for hours, days, or even weeks as needed while IT services staff resolve whatever issues may have caused the original server to crash.
Implementing an instant recovery approach is best done within the framework of a managed program model for providing IT support and services.
