NDMP Support on WSS

NDMP is a protocol not a peice of software, so you can use it any NAS device that supports it..it's not dependant upon the host NAS OS. To use NDMP you normally have to have some sort of fibre channel backed on the NAS (as this is used to direct connect to the tape device), but on some devices it can be normal metal scsi. What are to models of NAS and tape library???? Also what backup software are you planning to use??
Let us know and perhaps we can help.

No, you can not use NDMP on WSS.  That is because NDMP is only for NAS devices that do not have enough of a main-stream OS on them to use an actual backup client.  NDMP allows the backup server to issue the backup with the backup device, but then stream the backup data across the storage network from the NAS device.  

You can use a regular backup client for the WSS.  It is also much cheaper to use a regular backup client.  

NDMP has several limitations, including transfer speed, which is limited to 8MB/sec in NDMP v3 and 25 MB/sec in NDMP v4.  This is a protocol limitation, and not a hardware limitation, so use something like an LTO2 drive here.  Also, with NDMP, unless you are using the latest Veritas NetBackup, if a backup fails, you have to start it all over again.  Veritas (and I believe TSM so far) is now including a checkpoint feature that lets you continue an interrupted NDMP backup.

Does that mean that NDMP is hardware dependant?  Lets take for example that i already have a working NDMP set up and right now i just bought a Windows OS NAS box and i want to integrate it into the existing set up. Is it possible?
