Backup of data is one of the most important parts of any photographers workflow, and if you get to the point of doing work for others it becomes essential.  If you have invested lots of time in making photographs you want to make sure that you back them up, because ultimately you want them to be around for a long time.  Hard drives crash, computers get old, phones get lost etc. I hope I don’t really need to convince you too much that you need to backup.

So what is the best strategy? Well, for me it is the one that works continuously, reliably, and without too much intervention from me to actually take place!
