Jessica,
ndmpcopy, at the command line of a UNIX admin host works very well, particularly if you have a GbE (Gigabit Ethernet) connection for filer to filer data migration at any level - volume or qtree, even data from one location to another on the same filer. The form I use is: $ ndmpcopy filer1:/vol/volname/qtree filer2:/vol/volname/qtree -sa root:password -da root:password -dhost GbE_IP_address -level 0-9 ndmpcopy is downloadable, compiler for Sun, from the site: http://www.ndmp.org/ http://www.ndmp.org/
If you have a license, SnapMirror works really well too, but at the volume level. More to setup but less impact if outage is required.

What are your recommendations of copying data from one filer to another?
I have estimated time of 28 hours to transfer 70 GB via a copy command on the host machine.
I have tried to copy via CIFS accessing from NT servers using drag and drop. Encountered errors which halted the copy process due to files that were linked to incorrect locations. Unix files in the users desktop were linked to other machines and the path was invalid. Did a grep to locate these linked files in the user folders, and found too many to change one by one.
The vol copy command is only useful when copying from volume to volume on the same filer, correct?
I am looking for the most efficient way to move data.
Any suggestions would be great!
Jessica

This is the greatest failing of ndmpcopy... plaintext passwords to privileged accounts on the command line, in your shell history, up there in a "ps" for everyone to see, etc. It would be nice to have an "ndmp" user on the filer that can *only* initiate or receive NDMP sessions. Combine that with a new ability to read user/password information from a file in ndmpcopy, and you at least have some modicum of security. One of these days, I'll hack ndmpcopy to do that... unless someone else has done that already. ;-)
