How To Set Up a Two-Way Mirror Between Mac OS X and Ubunt...
After my hard drive crash a few months ago, I’ve been a bit paranoid about losing data. By “a bit” I mean I’ve been sticking copies of my data on different machines to make sure I have various copies in case another hard drive dies, or a computer gets fried, melting everything inside, or my house burns down… Oh wait, I don’t have that scenario covered…. Time to fix that! What I want is the ability to copy my data to an offsite location, and keep the backup up to date. The main thing I care about is my family photos. I was talking to my cousin Dave, and he had the same issue. He wanted access to my photos, as well as have an offsite backup copy of his family’s photos. I thought of a solution. What if we could set up a two-way mirror between his machine and mine, and keep it updated nightly? That way if he sticks something in the directory on his machine and vice versa, keeping a live backup. I began doing some research, and I found the tool — Unison.
