No I'm not unixified...heh More than likely I will just do it over a switch I have here in the office over the weekend. It is two windows systems (2000 server and 2003 server that house all of OMRF's imaging files for all the imaging facility users, so I have to make sure everything is double and triple protected. I can't rsync since it's windows based, without going through a lot of hoopla with Cygwin (which I could do but by the time I had it figured out I could have done it the hard way) ;) The 2000 server is an adaptec 2200S attached to a 10 drive RAID5 array, the 2003 server is a 2200S attached to a 10 drive 1.2TB RAID5 array. They both have external connections, but since both are mounted by their own cards, I didn't think you could. The whole reason for this is we got a new tape backup system that will do 600gig, which will cover our whole imaging server. Right now we have 4 partitions of 60 gig so we can fit each array on one tape for full backups. Now I can get them all in one tape, but on two of the arrays, I need to expand them since they are filling up so fast, and a few others I need to shrink. Before I start tampering with the array though, I'm going to do full backups on tape as well as copy over to a new server, then blowout and rebuild it into one array (for both my sanity and for administration purposes on my end). I have a gigabit switch in the office that I'll just drop between them and get it rolling on saturday and come up on Sunday and get the array done. I'll have it all on tape as well as doing an integrity check on the data moved. Then move it all back and be done with it (I hope). At any rate, thanks all for the comments and help.

Didn't know you were still alive. I have no idea what Imaging 1 and 5 are. I don't know how transferring 500G will affect the rest of the network. What do you think?
