While setting up Retrospect, I ran into a number of problems, most of which I think I solved. I’m just noting some of them here, so I can find them again. Or so you can find them, perhaps. I’ll add to this post as I encounter more oddities.
Now that Crashplan for home is gone, or at least not long for this world, a lot of people will need to find another way of backing up their stuff. It’s tempting to get angry, and there are reasons to be, but in the end you have to forget about all that and move on. Even though you may have months, or even a year, before Crashplan stops working, there is another reason you have to get something up right now, namely file histories.
