I've got a number of external hard drives from 300 to1tb and am trying to both back up and consolidate files on them onto 2tb drives. I need a program that will recognize when I'm duplicating a file even if its not in exactly the same folder structure. In other words I just need one copy of each file on the master drive and then it needs to have a copy made of it. I couldn't find a better category for this question so I thought I'd try it here. I'd appreciate hearing some recommendations for a program that also offers incremental backup options and isn't too complicated and, of course, I'd like to pay as little as possible. Thanks

In order to verify dupes, you would need something that an generate file hashes and compare them, this can be a tim consuming process. It could be done with some forensic software but it would require all the drives to be backed up are mounted at the same time. Off the top of my head I don't know of any affordable de-duping backup software.

Thanks. No idea what file hashes are but sounds too technical to be the simpler system I'm looking for. Could you tell me what backup software you use or recommend? Thanks
