I was also curious about a complete backup for my PRS-650 (in case of emergency). Up to now, I use a folder on my HDD and sync the device with this folder using SyncToy (you can "synchronize", "echo" or "contribute", I use "echo", i.e. new and updated files are copied from the Reader to the backup folder, renames and deletes are repeated. So, if I copy this emergency backup folder to an SD card, I either have to zip or rar my HDD backup folder or just don't insert the card into the reader, right? Thanks a lot.
