The bar is pretty low: your grandkids only need to be interested enough to keep some tiny amounts of data around. (Assuming that data capacities keep growing, your perhaps dozen of TiB of data will fit on a thumb drive in the future, or perhaps even an email attachment.)
Also your descendants don't need to find your data interesting for the same reasons you do. You might snap some pictures of your travels to famous landmarks (which your grand kids don't care about, because they can't find much better photos of the Eiffel Tower online), but they might be interested in how fashion changed over time, or weight or smartphones or whatever is in the background.
