Symantec is releasing a data backup product Monday that the company claims avoids risks associated with tape backup systems.The software, called the NetBackup PureDisk Remote Office Edition 6.0, is aimed at enterprise-level customers, particularly those in remote offices, said Wim De Wispelaere, senior product manager. PureDisk is derived from Symantec\u2019s acquisition of DataCenter Technologies, based in Belgium, in April 2005. Symantec estimates that 35 percent of corporations\u2019 data is located in remote offices, and the volume of data is growing at a rate of 50 percent annually, De Wispelaere said.PureDisk is administered through a Web interface that allows for different rules to be set for different users, De Wispelaere said.Typically, a non-IT person is responsible for maintaining backup tapes at organizations. "There\u2019s a lot of room for human error," De Wispelaere said.Recent high-profile cases have highlighted problems with the theft or loss of the tapes, which must be periodically transferred to a data warehouse, he said. Symantec\u2019s software transfers data encoded with 256-bit encryption over the Internet to disk storage at another locale. The software also has replication features to send backed-up data to another central data center for consolidation, De Wispelaere said.PureDisk uses a technology Symantec calls "global single-instancing storage," which identifies multiple copies of the same data. That data will not be backed up again, saving bandwidth and taking up less storage capacity, De Wispelaere said. The technology can detect modifications to a file on the segment level so only the unique changes will be transmitted.Pricing is based on the volume of backed-up data, which is compressed by PureDisk. A 1-terabyte license is\u00a0about US$24,548.-Jeremy Kirk, IDG News ServiceCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
