Since the format of the backup is not covered in the NDMP spec, each vendor was
free to create their own backup format -- and they did. They each had the same
idea of using a "Unixy" format, and hacking it in some way to support Windows
ACLs. While any two of them may have chosen the same original format (e.g.
dump/tar/cpio), each vendor hacked the format in their own way to be able to
store windows data.

Darren - I concur, but let me make a distinction. The Solaris ufsrestore
utility and reading a NetApp NDMP image (which uses a similar format to
Solaris' ufsdump utility) are compatible (mostly).
This being said, I did not require a NetApp to do the restore using this method
- in fact, I did not require Veritas either, only Solaris and an attached AIT-3
drive, BUT given an ideal scenario (AIT-3 drives attached to a NetApp filer), I
would have rather used Veritas natively to perform the NDMP Import and Restore
to guarantee a proper restore of the data.
Do other NDMP-supported NAS use different formats? If so, do they also require
same-platform to do the restores? Just curious - my only NDMP experience has
been with NetApp.

I would amend that to *netapp* NDMP backups. For any given platform,
there might be a solution.
In the general case, there is no guarantee of being able to do a restore
to anything other than "the same platform".
