Continuous Data Protection Offers Better Backup and Recovery

Tape backup is a relatively reliable and affordable data protection method, especially for long-term protection. According to CIO, however, as data volumes have grown and dependence on data availability and fast recovery has increased, the limitations of tape media have become severe.

"Most tape backup implementations use backup agents on application host servers to back up data from servers, consuming application host processing time. In some cases, server backup can impact the server itself enough to affect application performance. Furthermore, the explosive growth of data has expanded server backup requirements to the point where completing backups within the time available has become nearly impossible.

"The CDP concept has emerged as a way to better protect data and improve its recoverability, leveraging disk-based data protection to enhance the effectiveness of tape backup. By offering continuous journaling, CDP technology protects data for a much longer period of time than tape backup, reducing the required frequency of tape backups. CDP provides the capability to replicate and maintain multiple versions of data at local and remote DR sites for online data retention and recovery to any known good point in time."
