How Frequently Should I Back Up My Data?

Backing up data is a critical process for any business to ensure the continuity of its operations in the event of a disaster. The frequency of backups, however, depends on several factors that are unique to each organization. One of the most critical factors is the recovery point objective (RPO), which sets the benchmark for the maximum amount of data that could be lost in case of a disaster.

Another crucial factor is the recovery time objective (RTO), which determines the amount of time it takes to recover data after a disaster strikes. The maximum tolerable downtime (MTD) is another important factor that organizations need to consider while deciding on the frequency of backups. MTD identifies how long the company's critical services can be down in case of a disaster.

All of these factors are usually identified during the business continuity planning exercise. This exercise helps organizations identify critical services, how long they can be down, and what the risks are if they go down. It also allows organizations to plan appropriately and establish recovery procedures based on their maximum dollar tolerable downtime.

The frequency of backups depends on the recovery point objective, the recovery time objective, and the maximum tolerable downtime. Additionally, external factors such as regulatory requirements and contractual obligations with customers may also come into play. Therefore, it is essential for organizations to conduct a thorough business continuity planning exercise to identify the right frequency of backups for their unique requirements.
