Probably horribly patronising but:

1. Are you rsync-ing over SSH? What ciphers?
2. What ciphers and modes for LUKS?

(I'm assuming that thing's processor doesn't have hardware AES but I might well be wrong.)

On 2, it's probably not worth the arsing about but cryptsetup benchmark insists that twofish is slightly less taxing for my machine than AES.

1) No because it's in a lan, so I just use NFS.
2) I just did a basic 'cryptsetup luksformat' on the drive.

When building the vm box upthread I had to move files onto the drive out of a veracrypt store that was twofish(aes)) and it took 3 days to shift it over, I think there was an IO bottleneck though as it'd slam data between the vm's at 1gbs for a few seconds then do nothing for tens of seconds. That was between two vm's and sucking from usb2 though. It took a lot less time moving the files back onto the luks drive (done on a single vm-> usb drive).

I'm not really interested in speeding it up, it'll do for sitting around waiting for a cron to push back to it.
