The usage of a back-up strategy by businesses is growing organically. Thinking about early days, manually copying the essential files to a detachable media was a hectic task to the system administrator. In earlier times, a stack of floppy disks would have been sufficient, but as time passed, the storage capacity increased, and the detachable media also expanded its range. Then we saw tapes and hard drives of much higher capacity.
The Decades When Point-in-Time Backups Were Enough
Since the volume of the data back then was comparatively small, this method was enough. A single copy of the complete data, taken at the time of significant data operations was sufficient then.
Later, the dropping costs and rising revolution in the technical upgradation lead to the need for an increased understanding of data importance. This growing knowledge about the importance of data created some problems too, although. The expanding amount of data stored could not be quickly transferred to any external media when any back-up source had to be created in an overnight.
And, obviously revealed a further issue with the traditional back-up techniques, which was to recover the lost data in minimal time from the back-up source. It usually takes three hours to retrieve the data after a disaster. More significant back-ups were possible to put into multiple devices, but the gathering of those to recover a full system was a strenuous task, and hence it took days! So, it was inevitable that your business could suffer for days before it runs with a full fledge.
