I know this is generally a really bad idea but I will explain my reasons for wanting to make this possible.
Ubuntu Server 16.04
I run two machines that are not used as user machines one hosts OC and the other a CrahPlan install among other things. I have our family photos on OC as well as my Music collection. I have in the past used CrashPlan to back up theses collections.
With CP I have an on site BU but also a friend and I offer each other off site. Which was very useful in a recent HD fail.
My new set up with OC is raided so slightly safer but I would still like to be able to have off-site via Crash plan.
Any suggestions as to how to make this possible.
