Once upon a time, RAID was good enough for us. But now we deserve better.

RAID is what's primarily available to us, but that doesn't mean it's what we want. To quote Henry Ford talking about cars, "You can have any color you want, as long as it's black." RAID was built to improve performance and, more importantly, for protection in the case of drive failures. And because disk drives do three things (read, write and break), RAID has been essential over the years. However, the world has changed radically since RAID was invented. There are storage systems that now minimize the use of RAID and others that are moving away from RAID completely. RAID was developed at a time when disk capacity was expensive.

More Than Just Backup
Data protection is changing rapidly, with point-in-time recoveries, fast legal discovery response and near real-time disaster recoveries becoming new requirements. To address these needs, enterprise backup applications are adding support for continuous data protection, deduplication, ediscovery, single-instance storage and the VMware Consolidated Backup framework. These backup suites promise not only integrated data protection, but overall enterprise data management.
