Distributed ROBO backup to disk
Distributed ROBO backup to disk is the first data protection technology designed specifically for ROBOs. It has been around for nearly 20 years, but the technology has only recently been available for license by end users. Distributed ROBO backup to disk protects data for a wide variety of operating systems in servers, desktops and laptops that range in size from a single user to hundreds of users. To do that effectively, these backup products or data services need to be more efficient than traditional backup or replication technologies, and easier to use. Most of the products provide multiple point-in-time data versions similar to continuous data protection (CDP) products.
The ROBO WAN efficiency comes from deduplication (locally and globa...

lly), transmission of delta changes and compression of the remaining data. Distributed ROBO backup-to-disk data is deduped across the WAN in flight and at rest. DRO, skinny pipe and WAFS data is only deduped in flight. In addition, local deduplication takes place at the ROBO location, while global deduplication takes place at the central data center site. Global deduplication removes the duplicates among all of the ROBO sites.
The significantly reduced protected data will usually make disk storage less expensive than backing up to tape. In fact, there's no need for tape, tape libraries or virtual tape. Recoveries to the ROBO are also a great deal faster since the data comes directly from disk. For archiving, backups can be moved to tape or optical media as the protected data ages.
