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.
