Hi Kevin, 

I'm not a systems manager so my apologies if I'm a little lost here. I'm an 
audiovisual conservator/archivist and I use rsync for transferring files, a 
lot. 

Yes, I connect to the server and then it shows up as a disk on my desktop and I 
run rsync between the external drive mounted on my computer and the now mounted 
server. So, this would be a local copy? And, therefore, there is no way to 
invoke --partial because --whole-file is forced?

I don't quite understand what you mean by "rsync isn't doing the networking", 
but if it is not doing this then is there no checksumming occurring during the 
transfer? Unless, of course, -c.

Thanks!

If you are doing a local only copy (rsync isn't networking) then --whole-file 
is forced.  There is no benefit of reading and checksumming files to reduce 
network transfer when there is no network transfer.

You said you were moving data to a remote server so I assume you are using a 
network mount of some kind to make it a local copy instead of letting rsync do 
the networking.

Anyways, if rsync isn't doing the networking then forcing it to do a delta 
transfer would only make it take even longer.
