"same vendor of course" - that's pretty important for only 4 words.
we've all had to recover things from tapes that are years old. recently i had to recover something from a 1/2" 9 track tape that was a decade old.
10 years ago i had no netapps. in 10 years i might not have any netapps. requiring a specific [10 year old] disk platform to make my recover possible is silly.
what i write to a backup media should require nothing more than a device that can write that media. the original location of that data should not play *any* role in restoring from tape to disk. i have a hard enough time ensuring access to 8mm/4mm/DLT/9track/whizzbang without worrying about having available a ultrix/sunos/hp/solaris/dg-ux/4.1/vnix/qnix/vms/tops-10/whatever system.
vendors that open a connexion between a media device and an ndmp dump process, only to claim later that "hey, we don't know what the ndmp format was, so how can we restore it without having that vendor's product available?" are severely missing both the boat and my personal recomendation.

FYI
VERITAS NetBackup NDMP fully supports (release 3.4 onward) restoring NDMP backups to a different NDMP host (same vendor of course). The general NetBackup term for this is "alternate client restore".

Jan,
I am sure this trick is not supported officially by Legato/Veritas/others, but this has been used successfully, and is VERY easy to do:
Just edit /etc/hosts file on your Legato host to point the need-to-be-recovered
filer to the IP of the one that's replacement.
As NDMP doesn't really care about that, as long as the restore path is fine...

Hello list,
possibly you read the following line in the Legato's Networker 6 SysAdminGuide
The Networker Administrator Guide (6.0) shows in chapter 12 , the section on NDMP limitations the following :
NetApp Computers and NDMP Keep in mind the following limitations when you use NDMP and NetApp: * You cannot recover a NetApp NDMP backup to another NetApp. You can only recover data to the original host.
Does this mean that my faith fully daily made backups are worthless in case of a disaster?
rgds,
Yann
