We have been struggling with this for about 2 years now.
Here is some information from my experience.
Our NT admins bought some auspex NAS servers (NS2k)
and told us about it after the fact. Luckily, they
only used the NFS portion of the box. Until 2 months ago.
We have been NFS mounting to another "supported" server, then backing
up the data with DOMAIN statements in the dsm.opt.
The problem with this (which is affecting us now) is that
we only back up the the unix file permissions, and can't
get the NT ACLs. without an NDMP supported client,
its one or the other, but not both. This may not
be an issue with email delivery though.
We felt this was better than installing the old auspex
client on the server, just so NAS can do what it was made for,
servring files and not running some weird application
As to NDMP support in TSM. I have talked to the Develepors
a number of times about this, and they promised me an NDMP
client by the middle of first quarter this year. Last I heard
it was middle of second quarter. From what I can tell the
only benefit of NDMP has over NFS mounting/backing up
is that you can get both sets of ACLs.

Subject: email appliances and TSM
Hi all!
I need some help!
We are presently looking for a 'NAS' type solution for email delivery. At
this time, we use a large number of UNIX boxen to relay, route, deliver, and
store *vast* amounts of email for 48,000 students/staff on our campus. We
have
been approached by several different companies that provide 'dedicated
appliances', that do everything from scoop to nuts when it comes to email.
When I sit in the meetings with these folks, I ask the hard question... How
do we do backups? There answer is 'duh.. don't you use Legato or Veritas?
We
support those natively' 'Grrr', I say. 'No, we use TSM.' 'oh', they say.
Then, we start getting technical, and they tell me that they do 'expose
NDMP'
and TSM can do that. Well, not exactly true. Tivoli has not GA'd an NDMP
client yet, and NDMP is not exactly a pretty protocol for backup/restore.
What I am looking for are others, especially Universities, that are using
ADSM/TSM to back up email, that may be interested in looking into integrated
email solutions. If I can actually tell these vendors that TSM is widely
used
by universities (and of course, others) for this type of application, they
might actually think about supporting it. I am sorry, but Veritas is *not*
the only enterprise backup software solution. NAS vendors should start
looking for better ways to do backup/restore in large environments.
I would also be interested in hearing what others are doing in large
capacity
email shops. Are people using appliances? Do they support TSM? Anyone
doing
NDMP?
Feel free to reply to me directly. I will not give out names or email
addresses to sales people either!
Thanks in advance!
