Uuuuuurgh – more tedious than anything else. I use Acronis Backup. Take a full back up about once a month and then schedule an incremental back up every morning. Both partitions. At any time I can mount to the backup from any day and retrieve that file from yesterday I just deleted by mistake and as necessary (which it might be today) I can rebuild a brand new disk on the same laptop within a few hours. Worth every penny.
