Geoff,
Easiest and fastest is to set up crossover cables and use snapmirror. If you have multiple interfaces free (a quad card maybe) interfaces can be trunked with vif; with a single crossover line I saw a vol with 185 gig of data mirrored in about 6 1/2 hours.
Syntax is dead easy, source -> destination; waldorf is the source filer here.

I am contemplating moving an entire filer from 18 GB drives (many, many problems) to 36 GB drives; the reasons are an entirely separate posting. My question is, what is the fastest, most reliable way to move the data? This past weekend, I moved about 100 GB in four different qtrees with ndmpcopy, and each qtree averaged about 40 hours to move (between 34 to 44 hours). I am looking at moving three times that amount of data on this other filer. I seem to recall using snapmirror or snaprestore when we migrated from an F630 to our F760C, but that was quite some time ago. I was wondering if anyone had stories, recommendations, pointers on what is the best method to transfer data.
Thanks to all in advance!
