Hi Jessica,

ndmpcopy is a great way to go. There are compiled versions on the NOW site, and the source code is on the ndmp.org site.

ndmpcopy starts a dump on one filer and pipes it directly to a restore on another filer (or the same filer). It can be done on a directory level. It will preserve all of your unix permissions and NT ACL's when making the copy. It is also a much faster way to transfer data because there is no intermediate machine involved in the transfer.

Yes, volcopy will only copy entire volumes.

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
