Symantec's argument is that deduplication of data is an essential component of effectively and efficiently backing up and archiving data.
Think about it: How set up are you and your systems to remove duplicate data? How clear a picture, for that matter, do you have of just how much of your data is duplicated, and where those duplicates reside? How high are the storage costs the duplicated data incurs?
Symantec's approach to the issue includes elimination of duplicated data over WANs, dealing with duplication issues that arise from remote offices as well as backup and recovery sites.
Symantec's announcement states that client side deduplication also "reduces network utilization by up to 90 percent."
Likewise, recovery of backed up data will be speeded up after the elimination of duplicates,
Backup Exec 2010 includes unified archiving tools for Windows and Exchange, and also deduplicates server-side data, improving Exchange and Server performance.
Targeting midsized businesses, Backup Exec 2010 will carry a suggested price of $1,174 a media server license and Basic Maintenance. The Backup Exec 2010 Suites that include deduplication and archiving options have a suggested price of $2,708 - $3,888, with Basic Maintenance.
Worth a look, depending on your budget.
