BOULDER, Colo.----ProStor Systems, the leading developer of removable disk storage solutions, today announced that its line of RDX® drives and media have been certified compatible with leading backup and recovery software products CA ARCserve Backup, EMC Retrospect, Symantec Backup Exec and Yosemite Backup.

Certification of RDX removable storage technology with third-party backup software ensures that users can safely and securely protect their business-critical data and be able to quickly restore the information when needed. By testing RDX with a broad range of backup applications, ProStor provides users with a safe choice when it comes to making data protection decisions. ProStor Systems is the first removable disk drive vendor committed to providing interoperability with all leading backup software. This protects user investment in legacy programs and ensures that they don’t have to learn the nuances of unfamiliar backup applications.

“We believe the versatility of our RDX technology is a key factor in its rapid adoption by SMBs as a replacement for tape solutions. By confirming its use with all leading backup software, we provide users with more flexible options over other backup technologies,” said Bob Williamsen, vice president of marketing for ProStor Systems. “Certification with EMC Retrospect, CA, Symantec and Yosemite means that there are no issues with the safe backup and restore of our customers’ important data.”

The RDX removable disk cartridge developed by ProStor Systems replaces low-end tape technology, including 4mm DAT, Travan, VS-DLT and 8mm, with a new solution that offers higher capacity, faster speed and lower cost. Deployed to back up and archive data from servers and workstations, RDX removable disk technology provides a safe, easy-to-use and portable storage choice for SMBs and SMEs. In addition, desktop computer users who employ external USB HDDs to back up and archive their personal email, documents, digital photos, videos and music can take advantage of the affordable RDX solution, which allows users to save their data onto palm-sized cartridges and remove them for safekeeping.

To view an RDX system, please visit ProStor System’s booth PP28 at SNW Spring in San Diego from April 16-19, 2007.
