Continuous data protection

Continuous data protection 20.10.09

Continuous Data Protection does not run on a schedule like traditional backups. What does this mean? It is event-based and can provide continuous 24/7 data production, with support for Recovery Point Objectives as low as 1 minute. CDP is designed for remote backup operations with support for automatic re-connection and resumption in the event of a connection failure. CDP removes the data loss vulnerabilities between regularly scheduled backups as the backup window and recovery time objectives are significantly reduced.

Things to look out for?

Be sure that your service provider monitors the specified data source and whenever changes are detected, data is automatically backed up offsite. Is your service provider minimizing the bandwidth demands for CDP?

What are the encryption levels?

Additionally, backup data sent over the Internet from a remote site to a datacentre needs to be protected by encryption AES 256 in flight and at rest.

What bandwidth do I need?

A very fast connection is not necessarily needed to support CDP. Lower bandwidth connections can be supported. For example, an administrator may want to capture 1GB of changed data per second. If his connection is not good enough to transmit that changed data successfully, he may be able to transmit changes every 10 or 20 minutes. Check if bandwidth-throttling is also integrated into the solution.
