Our NDMP backups on Windows of Celerra's also has the -M -T dump
parameters, and ours also won't rename the recovered file. Legato says
it doesn't have that capability. Go figure.

Subject: [I] Re: [Networker] NDMP backup of EMC Celerra on NON-NDMP tape
drive
We have a Solaris 9 server at 7.2.1 and we run our Celerra backups to a
adv_file device. We do a full every month, level 1 every Saturday, and
a level 9 every other day.
backup command: nsrndmp_save -c hostname_of_nas_interface/client_name -s
backupserver -I indexserver -M -T dump;
>From the man page:
-M An NDMP client will be backed up to a NetWorker storage
node by
the nsrdsa_save program. This option provides most of the
Net-
Worker storage node features, such as backup to disk,
multiplex-
ing, automedia verification, and staging. The nsrndmp_save
pro-
gram spawns nsrdsa_save locally. A NetWorker storage node
host-
name should be listed in the "storage nodes"
attribute of
server's client-name resource.
Notes:
Save sets that are backed up by nsrndmp_save via
nsrdsa_save
will be treated as regular NetWorker save set and will
have save
set flags as 'N' and 's'. 'N' indicates NDMP client
and 's'
indicates backed up to NetWorker storage node. See
mminfo (1)
for more details.
application information: HIST=y, UPDATE=y, OPTIONS=NT, DIRECT=y;
The above will allow the recover of a single file to the NAS without
going through the whole save stream, from what support told us and our
testing did confirm that. Only gotcha that we had is that the recover
did not rename the file, it overwrote despite setting the option to
rename. Also, with the EMC Celerra you have to put all the filesystems
in explicitly and not use saveset ALL.
As for speed, our NAS is 3x faster at backup then any of our windows
file servers at backups.
