Backing up temp and cache files is ridiculous. They're not your data, they're the applications and OS transient data stores and are recreated automatically, dynamically, as the system and applications run. Backing them up is simply a waste of space in the archive. I use the incremental Backup application to do all my regular account things and exclude all transient temp files and caches, as well as the photographic files. Photo files are large and I don't want to use incremental backups on them ... that would waste a tremendous amount of space as well. I only want the latest versions replicated in the backup stores. I use a file synchronizer to back them to the archives specifically rather than an incremental backup utility. It proves to be an efficient system. The photo backups run every evening automated, or when I say "do it now", the main system backup runs every week. Backup storage capacity is consumed at an economical rate this way.
