Disaster recovery begins with a solid backup plan, accompanied with a sound hardware solution.
Good backup processes are difficult to practice.
These products make the backup process and recovery more efficient. Having a centralized storage point for all PC's and backup images. This centralized storage make accessing the information easy and convenient for the office business plan. No more fighting, or working on the file sharing strategy. Although better than nothing at all, backing up to a USB drive, is just a thumb pull away from disaster. Once more, a thumb drive cannot backup an entire computer, much less 10 computers.
