Application downtimes and data loss are less than ever caused by hardware problems. More than 80% of all downtime incidents are actually caused by software or user errors instead.

These are exactly the areas where traditional concepts (e.g. RAID- und Cluster) will fail in providing protection. Redundancy will be of no help in case of corrupt or deleted data. In this case, resuming business operation will require a manual restore from tape or disk image.

This is not only annoying, but also very time-consuming.
