I've had good results moving storage pools between RAID devices (for maintenance) using xfsdump and xfsrestore. I'd recommend that you investigate the dump/restore commands for your filesystem (I've learned to avoid ext for anything over ~1TB but YMMV).
For locally attached devices, the rates were competitive with all other methods I tried. You can use dump/restore commands over the net from one server to another, but beware of the overhead of your transfer protocol (if you're using a ssh tunnel choose your cipher wisely to reduce overhead). Hope this helps.

However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925 - Fundamental truths of networking On Thu, 21 Dec 2006, Mike Sauer wrote: > I've has success using PAX to copy ~72GB of data. > > pax -r -w /old/path /new/path > > It took quite a while, far longer than DD would have, but personally > prefer copying on a file level to a device level.
