What is CDR Backup?
CDR backup is a process of copying electronic data from a computer's hard drive to a high capacity optical disc with 650-700MB of capacity. CDR backup has been around for more than a decade and was popular due to the very low cost per megabyte (about a tenth of a cent). Since the advent of DVD burning, CDR backup has been deemed obsolete.
CDR backup is effective for single user computers and is most widely used with home computers. At a small or medium-sized business, the lower cost is outweighed by the management and human intervention required to perform an effective data protection strategy.
CD media has to be changed by hand and archived daily. When the media capacity fills it needs to be replaced with blank media, and backups will not span across multiple CDs. Disk-to-disk technology provides the lights out management schedule required to provide a consistent, auditable and reliable data protection and rapid recovery strategy.
