Quantum Rolls Back CDP Project

While the ranks of companies embracing continuous data protection (CDP) technology swells, one of the early proponents of disk backup has put its CDP plans on ice for now.

Quantum Corp. (NYSE: DSS), which added disk backup to complement its tape libraries in 2002, killed a CDP project that 10 engineers were working on last month. The CDP team mostly comprised engineers from SANlight, the startup Quantum acquired for $8.5 million two years ago (see Quantum Buys Backup Bunch).

Analysts consider CDP the next evolutionary step in disk backup. CDP software continually records data changes and stores only the changes instead of the entire files or databases. CDP also allows recovery from any point in the past instead of only at fixed intervals.

CDP appears a good fit for Quantum, which joins other tape vendors, Advanced Digital Information Corp. (Nasdaq: ADIC), Overland Storage Inc. (Nasdaq: OVRL), and Storage Technology Corp. (StorageTek) (NYSE: STK), in shipping disk-based backup systems (see Quantum Digs Into Disk Backup, Quantum Ships Disk Backup, and Quantum Slips Disks Into Backup).

SANlight was mum on its technology before Quantum acquired it, saying only that it was developing backup software. One of its engineers who joined Quantum says the startup was already deep into a CDP project called Excalibur before the sale. The engineer says the project continued at Quantum under the direction of CTO Michael Del Rosso but remained unfinished when the team members got their pink slips.
