yeeee haaaaaaaa!!!!
thank you Brian!
I even figured out how to run sshfs on my own!
for anyone who happens upon this thread with the same problem here is what I did:
sshfs <ip of computer to save to>:<path of directory to save to> <mount point>
(sshfs basically mounts a remote directory)
then
fsarchiver [options] savefs <mount point>/<filename> <device to save>
