In its first major release of key product NetBackup for two years, storage software company Veritas has given attention to “horizontal scalability” — coping with the multiplication of servers, rather than growth in the size of individual servers.
Despite the impression of endemic server consolidation created by some vendors and large-scale users, “horizontal” growth is still the dominant trend, says Simon Elisha, a Melbourne-based technical architect at Veritas.
“We have replaced our scheduling tool with more advanced software that we call the Intelligent Resource Manager,” he says. IRM matches up priorities in use of resources and time against all servers on the network that need backup. It was possible to do this under previous versions of NetBackup, “but it took a lot of user involvement,” Elisha says. The claimed “set and forget” design of IRM caters for the needs of the many organisations with a growing number of servers and not many administration staff.
NetBackup 6.0, the latest version, also improves operational reporting, in line with user feedback, he says. It provides fuller reporting of such information as media utilisation and backup completion rates.
Enhancements have been made to disk-based backup, where data is staged to disk before being moved on to tape, or retained long-term on disk. In partnership with Network Applicance (NatApp). Using NetApp’s NearStore nearline storage and an algorithm that re-stores only the parts of the data that have changed since the last backup allows savings to be made on disk-space, Elisha says.
NetBackup 6.0 was released last week at Veritas’s Vision user conference in San Francisco.
Also released at the same event was version 6.0 of the archiving product Enterprise Vault. Previously focussed on Microsoft Exchange, this now has Lotus Domino and SMTP support added. Veritas has also provided a software development kit to allow storage vendors to link their own devices into Enterprise Vault’s multi-level storage management routines.
