You might want to look at the new NetApp options in NBU v6.5. NetApp and Symantec seemed to have found a pot of gold in this NetApp data backup area. I recently asked for a quote on a NetApp (backup disk) solution to backup one of our 3050 boxes ... and they came up with a proposal that included a box bigger than the 3050 loaded shelves of disk and an abundance of software licenses. It *seemed* that NetBackup couldn't "see" what files were changed in the incremental snapshot changes, so at the moment I'm underwhelmed.
At this point in time, I like the simplicity of disk backup devices with inline dedup and internal function to long-term protect the backups (Data Domain seems to have the "right" idea to me). The NetBackup catalog will get large ... but doing away with tape seems a positive, not a negative, to me. This is a very interesting area and I'd love to read discussion from all of you. cheers, wayne Kenny wrote, in part, on 2007-07-26 11:39 PM: > I have a large NetApp environment and I am looking for a new strategy for > backing up my filers.
