Is RAID the only backup solution that I need? Is it even a backup solution?

RAID is not a Backup solution.  RAID creates a single usable data disk, where several physical disks are combined into an array for better speed and/or fault tolerance.


SoftLayer provides a few backups solutions:
  1. Evault Backup is an enterprise backup solution that can automate backups across multiple servers. Data is stored to an enterprise SAN (storage area network).
  2. Network Attached Storage (NAS) is an industry standard, and provides off-server storage for critical data. Data is stored to an enterprise SAN (storage area network).
  3. Idera CDP provides high-performance disk-to-disk server backup featuring a central management and data repository. Idera CDP protects data at block level, and unique disk blocks on the server are stored only once across all recovery points, increasing storage efficiency.
