Continuous Data Protection (CDP) is also known as continuous backup or real-time backup. It is a backup system that replicate every data modification into a storage media as the changes happens. In other words, it is a solution that empowers organisations to restore data at any point in time, letting them to have those updated data whenever needed. Significantly, CDP promises better data backup practices. Therefore, how does CDP solve traditional backup challenges?
Traditional Backup Challenges
In data loss event, it is all about achieving recovery within the maximum tolerable downtime (MTD). MTD is a component in Business Continuity Event (BCE) recovery referring to the acceptable period for a business function to experience downtime before the damages become irreversible. Nevertheless, traditional backup approach is lacking in carrying such mission due to decreasing backup window size, unavailability of backups, longer restoration time (beyond recovery time objective (RTO)), and failure of other backups copies due to ransomware.
How does CDP solve traditional backup challenges?
CDP is not objectively implemented to replace traditional backup, rather it helps solve the traditional backup challenges through its well-rounded backup and recovery strategy. CDP which is a block-level technology instantly backup recently modified data by recording changes at the block level. As CDP utilises operating system, it provides better data protection as it immediately detect changes on files and back up only the modified file instead of copying the whole files. Additionally, this strategy also remove the need for backup windows.
At its core, the ability of an organisation to recover before MTD is achieved depends on several other components in BCE including recovery point objective (RPO), recovery time objective (RTO) and work recovery time (WRT). CDP reduces RPO thus addresses the traditional backup challenges through its continuous backup practice, giving organisation with almost up-to-date recovery (near CDP) or completely up-to-date recovery of data (True CDP) which are essential in surviving such data loss events.
