I have a lot of lossless music on my computer. Unfortunately, sometimes (now quite rarely) they got corrupt and I had to replace them with my backup from an external HDD.The backup was done manually and it was of course tedious. As my music collection grew it became more and more difficult to find by hand which album weren't archived.What would be the optimal solution for this case? Simply cp-ing? Some rsync usage? I'd rather not update existing files - they hardly change and I don't want to delete good files with corrupt ones.
