"once a week" was maybe a too extreme example. For my case specifically: lost data can be recomputed. Basically a bunch of compiler outputs, indexes and analysis results on the input files, typically an order of magnitude larger than the original files themselves. Any files that are important would go to a separate, more reliable filesystem (or uploaded elsewhere).
