Data loss can play havoc in enterprise world and this was proven in a recent survey conducted by Federal Emergency Management Agency. According to the survey, there are only 40 percent of businesses which survive after a data loss and another 25 percent fail in just one year. This clearly indicates that approximately 90 percent of businesses have failed within the span of two years after it has been struck by an incident of data loss.
So, under these circumstances, having a backup copy of the entire enterprise data makes complete sense.
But can a backup of data alone save a business from losses?
No, a backup alone cannot save a business from downtime driven losses. Then what’s the solution?
Just follow the article further to know about the apt solution-
- To begin with, data backup is dependent on working systems to restore the data that is backed up. This is useless when there is hardware failure as during a natural disaster or act of sabotage. In these instances, users must first replace and reconfigure the hardware before the data is restored.
- Backups need scheduling processes where one should take the data backup on daily, weekly, or monthly basis. For how long? Till you want your business data to be available after outages.
In lieu of these disadvantages, a more sophisticated form of Data Backup has emerged in recent years, aptly called – Disaster Recovery.
Disaster Recovery or DR is an approach that replicates the map of the entire IT system covering end user computers, network files, all software programs and all data in such a way that they can be recovered quickly in case of an incident.
Since, DR is not hardware dependent all data; databases; software programs; Operating Systems and their settings can be restored to new hardware even if they have no software loaded on them. This is called as “bare metal” restore.
When new hardware is being ordered, or when a hardware failure has occurred, DR will restore the entire IT system onto the cloud and the same is recovered once the hardware is in place.
Needless to say, DR requires a bit of investment. But that investment will pay you back when an unexpected outage (man made or natural disaster) strikes your data center.
Finally, knowing the difference between Data Backup and Disaster Recovery is critical to a company’s operating model.
Whatever strategy is adopted by the organization, the focus should be not be on reducing costs in the short term but minimizing risk in the long term.
