Time-addressable and Event-addressable Storage: Combining Snapshots and Data Journaling for True Continuous Data Protection

CDP is a method of uninterrupted safeguarding against data loss or corruption, by using one of a number of possible services or methodologies. Generally speaking, CDP services operate by continuously capturing all changes to data and storing these changes in a separate storage location. CDP services also provide the capability for virtually instantaneous restoration of data to any point in time prior to a catastrophe or data loss.

This paper discusses, how replication that is both time-stamped and event addressable through the combined technologies of data snapshots and journaling is true CDP that offers complete system data protection. By combining the time-addressable and event-addressable data protection technologies of data snapshots and journaling, an application recovery-oriented solution with optimized RPO and RTO characteristics for any type of failure is now a possibility.

Until now, CDP has only been deployed in enterprise systems due to the complexity and cost of implementing a reliable solution. But by capitalizing on the unique features of snapshot-capable iSCSI storage appliances, and placing the CDP functionality within the software rather than hardware, CDP is now within the reach of small and medium-sized businesses (SMBs). The key benefits of CDP that allow organizations to reduce data loss (higher RPO) and perform quicker recovery of short-term data in the event of a data corruption or loss (lower RTO) are all presented at an attractive price in the innovative StorTrends® iTX storage software stack from American Megatrends (AMI).
