NetBackup Gains Speed, Strength

Veritas' latest version of NetBackup will boast improved speed, capacity and capability.

Veritas Software Corp. is planning to pump up enterprise backup with an upgrade that offers improved speed, capacity and capability.

The company in January will ship NetBackup 5.0, an upgrade to Version 4.5 that according to sources includes security features that will eventually link to other Veritas applications.

NetBackup 5.0 will come in two versions: Server, for single host/media, and Enterprise Server, for multiple host/media needs, according to users who were briefed on the product. The two-pronged strategy should help clear up customer confusion that came with NetBackup 4.5, which shipped in the spring of 2002 and was offered in three versions: Professional, BusinesServer and DataCenter.

A major new feature of Version 5.0 is Checkpoint-Restart for Backups. The feature puts boundaries around files, but not in files, to allow for automatic resumption if a backup is interrupted or fails. NetBackup 5.0 will support file sizes of 64 terabytes, with 2 million terabytes (2 exabytes) per backup, on tapes of up to 4 terabytes, compared with the prior specifications of 1 terabyte, 1 terabyte and 2 terabytes, respectively, in NetBackup 4.5.

Disk staging before data is moved to tapes, a trend gaining popularity, will also be supported. Synthetic backups are new as well, so users can create a full backup from previous incremental sets, resulting in faster restores.

Checkpoints and the new file sizes are especially appealing, said Mark Donaldson, senior systems engineer at Experian Information Solutions Inc. Donaldson learned about NetBackup 5.0 at a recent Veritas sales seminar in Denver.


"Some of this stuff is going to be a godsend," said Donaldson, also in Denver. "I have problems now where I cant back up one file system because its too big, so I have to break it up," which is "a major maintenance hassle," he said.

Regarding disk staging, "a lot of us have learned to home-grow this," Donaldson said. At Experian, "we call it Franken-array; its assembled out of our spare-part bin," he said. Experian will upgrade to Version 5.0 as soon as possible, he added.
