Using continuous data protection (CDP) for data backups

While continuous data protection (CDP) hasn't replaced traditional backup and recovery methods in today's market, CDP is widely viewed as a viable alternative to many backup and replication products. Continuous data protection offers advantages over traditional data backup products because of its ability to back up all data housed in a business anytime a change occurs. However, for organisations considering a CDP technology deployment, there are multiple factors that need to be looked at.

We've compiled our most recent resources on continuous data protection to help storage professionals navigate the CDP market, determine if continuous data protection is a more effective option than their existing backup technologies, decide whether near-CDP or real CDP is best for their organisation, and more.



Continuous data protection fits the bill for unstructured data protection needs
Approximately five years ago, industry buzz said continuous data protection was going to be a game-changing technology in data protection. Industry pundits were convinced CDP would replace traditional backup and recovery methods and become the dominant force in the market. So has the promise lived up to the hype?

Is continuous data protection effective enough to be the only full data copy for disaster recovery?
According to Simon Johnson of GlassHouse Technologies, CDP is effective against physical corruptions because it maintains one or more copies of your data, either locally or remotely, to ensure disaster recovery (DR) in the event of physical failure. But is CDP effective enough to be the only full data copy for DR?

The difference between continuous data protection and snapshots
Continuous data protection is a form of data replication, and is similar to snapshotting in some respects. Like snapshots, CDP replicates or copies data from a source to a target at an instance in time. However, there's one major difference.

Council uses continuous data protection to protect sensitive files
Brighton & Hove City Council is introducing continuous data protection technology to protect sensitive social services-related files as part of a wider move toward implementing a common data management platform. Learn why the local authority chose CDP over data snapshots.

Continuous data protection playing a role in data backup
Before most people ever heard of data deduplication, continuous data protection was all the rage for disk-based backup. But unlike dedupe, continuous data protection never made a great impact on traditional data backup and recovery products. However, CDP is now seeing a moderate uptick in usage now that it has evolved from a standalone product to a feature of backup and replication technology.

Continuous data protection: Near vs. real CDP
Continuous data protection and near-continuous data protection offer recovery options that are simply not possible with a traditional backup system. Both CDP and near-CDP support instantaneous recovery, allowing your application to immediately mount a recovery image when the primary image is damaged. However, the big difference between the two is the recovery point objective (RPO) that they offer.
