The save operation is going at a snail's pace, though. Using "watch du -skh", I counted about 5-7 seconds per .1 GB (1/10 of 1GB). It's a virtual disk, but I'm using over 200GB... so at this rate, it'll take a very long time.
I wonder if Pascal is on to something, and the export is happening over the frontend 1GB network? I'm going to cancel this operation, as the VM has now been down for close to an hour.
