THanks for all the information provided to this discussion. The reason for not 
using NDMP is purely for budget reasons. I will use the information provided to 
justify purchase of the NDMP client connection license and intend using it with 
DSA.

  In order to backup via CIFS you would need to either have a user
auto-logged in the console with the drive mounted as a user with enough
permissions to backup all NFS and CIFS files or you would have to have
permanent drive assignments which have their own set of issues with
security. Either way, it has both performance and permission issues. The
security issues may have not been an issue in the old days, but with the
Sarbanes/Oxley, HIPPA , etc, having a windows share open like that is
asking for trouble.

Again, other than the cost of the NDMP license (and if you have a legato
server and a NetApp, the license cost can't be a huge issue), what's the
issue of using Legato NDMP and DSA? The performance is very good,
especially if you dedicate a VLAN for it and use jumbo frames.

Other devices might do other things, but netapp specifically allows CIFS
backups to store and restore both CIFS and NFS permissions structures
(the NFS structure is stored in an hidden ACL entry).

This doesn't apply to NFS, which will be unable to handle the ACLs. (At
least that was true prior to NFSv4...)
