Misconceptions About Cloud Based Backup
One of the biggest misconceptions regarding cloud-based disaster recovery is it’s purported superiority to more traditional data storage methods. The technology has been marketed so heavily that there’s a perception among some users that any service can be made better by running it in the cloud. Some organizations are even ready to abandon existing backup offerings (that are working perfectly well) simply because they’re under the impression that they were supposed to move backups to the cloud in order keep up with the pace of progress.
While there are some things cloud backups do very well, some jobs might be better handled by a more traditional backup approach. Two major advantages of cloud-based backups are:
- Data isolation. Backups stored in the cloud are isolated from your facility, which means backup data will not be lost in the event of a facility level incident.
- The backup target capacity can be considered unlimited. You have to pay for the data storage resources you consume, but you do not have to worry about exhausting the available storage space. ‘Infinite scalability’ is key term used to describe this benefit.
But the most significant disadvantage to using cloud-based backups is that recovery times are simply limited by internet bandwidth. These constraints don’t just cause issues for large scale recoveries, but also for small or medium scale operations. There is always the option of sending customers physical storage devices containing data to reduce recovery times from weeks to days, but this defeats most of the rationale for shifting away from tried and true methods.
Cloud based backups will continue to mature and may eventually become a viable replacement for all backups. For now, one of the best strategies involves creating and retaining local backups while replicating those backups to the cloud for safe keeping. This so called ‘hybrid cloud’ technique is endorsed by most leading experts on the subject, and our team at The Data Vault has extensive experience molding our solution to fit any need.
