Backup has two problems; first is the time it takes to copy data to a secondary device, even with source-side deduplication and change blog tracking (CBT). The second problem is the cost of the infrastructure to support that transfer and store the backed up data. And recovery is even worse, since all the data has to come back (deduplication and CBT won’t help).
Clearly, it’s time to change the data protection rules and look at using array-based snapshots to address the cost and time challenges of traditional backup. In this article Eric Slack, Senior Analyst at Storage Switzerland, details the challenges to traditional backup and recovery architectures and discusses how array-based snapshots powered by flash storage just may save backup.
