Re: [Veritas-bu] VTL and Tape or SnapVault.
Hi Pat, What strategy are you planning for VTL to tape, thats where we had problems. Vault takes long so you would need to have more physical drives or less data to be vaulted.

Re: [Veritas-bu] VTL and Tape or SnapVault.
Hi Pat, If it was possible for me I would go with a disk based solution of some kind. And if you dont have the need for netbackup and already have netapp`s software onsite and are familiar with that software, maybe that is best for you. I would try to eliminate so many hardware/softwares as possible in the chain of handling backup and restore. Less is more. One box, one tool God, that would be great.. The important thing is not to do what everyone else is doing; it is to do what is right for your environment. If you dont have the need for netbackup and tapes, dont go that way. Although, if you have a large amount of data that you need to keep for 7 years, then maybe tape would be more economic. We are looking into VTL`s with dedup (awaiting netapp to release there dedup function), and hope to reduce the need for tape big time... If I could go all disk, I would. But with large data amounts the need for cooling, floor space, electrics and such tape still bring me a great value. Hopefully dedup gives us a more equal situation between disk and tape, and then, the choice becomes easy for me. Still I would like to replicate and duplicate data of to another disk or maybe tape for long time store.. Though it do feel a little bit scary to only have ONE baseline copy, but I guess that goes for other disk based dedup solution as well. Could you also replicate the backup box to another box? Now it starts getting to expensive maybe...

Re: [Veritas-bu] VTL and Tape or SnapVault.
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.
