Upgrading Netbackup hardware. We have money to spend - any advice?

Hi to all,

We currently have 1 x NB 6.5.4 (Win2003) Master Server with a SCSI attached Dell TLD containing 6 x LTO3 tape drives. Additionally we have 1 further media server (Win2003) which we use for disk backups (occasionally as it is extremely slow!). We also have 1 x NOM (Win2003) server and 1 x NB PureDisk (PDOS) server which has 2TB of local disk space. 

 We have noticed that since we introduced multiple copy backups and all 6 Tape devices are in use, the NB platform slows to a halt. We are going to try and spread the load around a bit more. Our thinking is that we buy a media server for each of the 3 LAN's that have servers that we backup (SQL DB and File/Folder backups mainly). Each of these new media servers would either have a lot of local disk storage or would use DAS hardware. We are keen to get more out of our PureDisk software and are considering beefing that up and making it a clustered environment to an offsite device.

Quite simply, I have been asked to provide a design document and I wanted to ask if anyone had any reccomendations on how they think we should invest? Our largest backups are around 2TB and these happen on a weekly basis. We also send tapes offsite on a weekly basis for the critical backups so we are not keen on disk-only solutions. We are happy to upgrade to NB7.0 too if this has any relevance with regards to our forthcoming hardware purchase.

Any advice greatly appreciated.....

Apples? Oranges?

I've alwasy been very partial to, and have seen great stats with Solaris hardware as master/media servers.  T5220's make for pretty good master and media servers.  I've yet to see one in my environment pegged out.

I would definately look at upgrading from a SCSI environment to fibre if you've got the budget to do so.  An SL500 library would be a good investment for a smaller environment, as when it is maxed out it only takes up 1 whole rack, and you can start out small with it and increase capacity as your environment grows.  Definately upgrade to LTO-4

Hire a good consultant.  :)

I agree with rjrumfelt move

I agree with rjrumfelt move from the Windows platform to a Solaris or any Unix OS.  In addition move from DC SCSI to a fibre connection solution.  With a FC Soulution, you would be able to share the resorces between multiple media servers.  I recommend looking a Quantum i500 with LTO 4 Drives.  Another thought, is look to a VTL Virtual Tape Library. I know Quantum and EMC have a version of VTL.

Best of luck

We utilize

one of EMC's VTL's at my current location.  It seems to do pretty well.  If I had my choice for disk however, I would go with a dedup solution such as DataDomain.
