RE: Legato Backups. - toasters

20 Sep 2002

      We've been backing up 3 of our filers over NFS for 4-5 years now with no
significant problems.  We've done lots of restores as well.  The only real
caveat would be that NT ACL's are not preserved, but since all our qtrees
are UNIX, that's not a problem for us.
We tried a demo of the NDMP Legato solution shortly after it was made
available, but we found it flaky and unreliable, so we went back to NFS.
I'd imagine it's much improved now over what it was then.

Erm...  Well sort of, and it works.  As far as I remember that's how some
data was moved about shortly after the install (of the Filer) early this
year.  But we've been discussing <bg> the supported framework ever since and
that is why we are moving over to NDMP very soon now.

But I cannot claim any great competency in doing it.  If we have that kind
of need (for now) we involve our support partner.

However I did speak to a techie deep within the bowels of Legato, and it's
essentially "of course it all works - why shouldn't it? but of course that's
not our position".
