This article is discussing a strategy for backing up photos while traveling, and then after a trip, but the same strategy is necessary for any important data, especially if you travel for work.
Important: It does not matter what system you use the goal should be the same. You need to have at least 3 copies of your images stored in not less than 2 different locations.
I achieve this goal by having my digital images stored on the internal hard drive, external hard drives, and cloud storage. 3 copies, 2 locations.
