When taking trips that last more than a day I always worry just a little bit about the risk of a burglary. What can I do to mitigate the risk of my computer being stolen and the data being compromised? My main strategy so far is to shift all useful data onto an external drive and take it with me on the trip, but I'm not sure that's adequate, and I'm not sure how to find the entire set of data that I'd have to shift.
I'm not prepared to take the kinds of steps that would be required to foil a determined thief; what I really want to do is make it so that if someone walks off with my computer I only have to worry about its replacement cost.
(I'm having a hard time finding an alternate question that contains what I want to know. This question is the closest but the answers focus on laptop physical theft prevention. Backups, on the other hand, give me data recovery but not security against data theft. If someone points to useful alternate questions and then closes this one, that's good enough for me.)
