Viewpoint: Backup & Disaster Recovery
By: Ando Ryu
Most organizations backup their data using standard software available in the marketplace names such as Backup Exec, ARCServe and NT Backup. The Backup policy usually includes important data that resides on file servers, database servers, mail servers, etc. The backups are typically stored on tapes or more recently, disc based storage. Generally, the backup process is “local”. That is to say, the primary data residing on the servers is backed up on premise or “on-site”. Most organizations consider backup to mean just that.
When you introduce the concept of backup and disaster recovery together most organizations would think of this consisting of two separate products and perhaps separate budgets. The backup piece as “on-site” and the disaster recovery piece as “off-site”. The price tag associated with disaster recovery can also be perceived as very expensive.
With the adaptation of cloud computing and more specifically cloud backup, organizations can achieve both backup and disaster recovery at a reasonable price. We consider this a hybrid approach to getting the best of both worlds in backup and disaster recovery.
On-site backup alone won’t help in the event of a site disaster of sorts. That’s where the off-site disaster recovery piece comes in to play. If backups can be stored in a data center facility with state of the art security, power, physical resistance to natural disasters then there is still hope of data recovery even if the primary site is compromised.
As more and more organizations begin to consider cloud-based services this hybrid on-site/off-site approach combining backup and disaster recovery together is an easy first step. Organizations don’t need to invest in new infrastructure with this approach as it is all part of the cloud package.
With the hybrid approach, everyday recovery needs from files and folders can be rapidly recovered via on-site appliance at wire speeds. And when disaster strikes in some form or another, data can be recovered from the off-site data center facility to a new location.
