Adobe Lightroom has a lot of advantages when it comes to keeping track of images, so I wouldn't discount it totally. In particular, it includes built in tools that aid in systemizing organization of files and ensuring backups, and includes a work-flow that helps protect against inadvertent write-over of originals.

Corel's Aftershot Pro has some similarities to Lightroom, and has the advantage of a license that permits using with each of Windows, Mac and Linux operating systems.
