I was just reading a great forum post by Stinsonddog (good guy by the way if you are looking for answers to hard questions) about using this application, Karen’s Replicator, to backup your BlackBerrys SD card when you connect it to your PC. There are hundreds of applications that do this but this application seems to fit the bill nicely because it is free, easy to use, and has quite a selection of options for configuration.
You can get the application free at the following link Karen’s Replicator.
The software allows you to automatically backup files, directories, or the whole SD card. The key feature is that you can copy only files that have changed so it does not need to copy the whole SD card every time. The software allows for such complexity that you can even specify which files should not be copied, and also which days a file should be skipped.
Thanks Stinsonddog for the tip!
