"It makes it possible to do backup replications you couldn't do before because they're too large," Lodge said. On NetBackup 7, Symantec added automated replication for deduplicated data, meaning only data changes are sent across a WAN to a secondary disaster recovery site, reducing the amount of bandwidth required for remote replication. "That way, you're not continuously backing up things that never change and are old." That prunes out the old content, and helps you reduce the size of your Exchange systems, which makes them perform better, and it improves your backup performance," Lodge said. "You might set up a policy that says, 'I want to archive anything older than three months in Exchange,' and then it will go back and delete those files from Exchange automatically. Enterprise Vault allows administrators to set up policies that automatically archive backups and then delete old files.įor example, using the feature with an Exchange server would allow an administrator to set policies that would archive and then delete backup images of a certain age. Symantec also added its Enterprise Vault archiving application, which already existed in NetBackup, to Backup Exec 7. That can improve performance as much as 10% to 20%, Lodge said. Block Optimization creates a single image for a virtual machine and tags blocks that are not being used so that they are excluded from the backup process. Symantec has introduced VMware Block Optimization on NetBackup 7 for virtual machine backups.
Symantec said it has also improved NetBackup's support for virtual servers and storage, particularly around granular recovery or virtual server backups, which allows the recovery of virtual server environments right down to a single file or e-mail, Lodge said.
"Our thought process was deduplication everywhere, but you have to make sure you manage that from a single place - in the backup application." "This gives you the ability to manage and control the backups from within the backup application, even though they're stored on a third-party device," Lodge said, pointing to appliance partners such as Quantum and Exagrid. "You're bringing enterprise -class technology - deduplication - into the mid market, and that drives really great storage and cost savings," said Matthew Lodge, senior director of product marketing for Symantec.Įnabling the data deduplication function on both NetBackup 7 and Backup Exec 2010 requires only a single check mark in a pop-up box, Lodge said.īoth products implement the feature at three levels: Source or client deduplication, which compresses data at the backup server media server deduplication, which aggregates deduplication for numerous backups and third-party appliance deduplication for virtual tape libraries and other disk-based backup appliances.
