For small files, bup's compression won't be as good as xdelta's, but for anything over a few megabytes in size, bup's compression will actually -*work*, which is a bit advantage over xdelta. +*work*, which is a big advantage over xdelta. How does hashsplitting work? It's deceptively simple. We read through the file one byte at a time, calculating a rolling checksum of the last 64
