There’s this very handy feature I’ve blogged about in the past : /home folder encryption in Ubuntu. This is clearly a feature I’ll keep on using as long as I use laptops.
But the Mac counterpart… Well, I didn’t use it. Then I used it. And it bugged me so much on the way it works that I’ve come to question using it, for the sake of my backups. This “silly” thing you see, is that I run my everyday Mac with a non-Administrator account, and I have a Time Machine disk backing up that computer. See the problem ? Backups will only be made upon logging out. And, most of all, you cannot restore files individually. Fortunately, there might be some light deep down the tunnel, and a solution in that post.
The trick explained here can somehow lower the degree of security of your installation since what we are basically going to do is to save the files in your Home directory while decrypted. Which means they will be unencrypted on your backup disk. In the case of a removable drive (like a 2.5″ USB HDD), that can be tedious. So, be aware…
