Hedge has added a duplicate file detector into its software, copying only what is new into your backup destinations. In previous versions of Hedge, the software has simply cloned the data from the media device such as an SD card or hard drive and copied it onto another. In earlier versions it hasn’t been possible to add data to existing folders. Smart folder analysis In this latest update, Hedge has added duplicate detection. The software automatically analyses the destination folder, and only copies the files that do not exist into that destination. For those doing an incremental backup (copying over data from one card, and then continuing to shoot on the same card to back it up later), this is a godsend. It’s automatic, but the file checking is not as simple as just looking at the file name. After all, you could be shooting on multiple drives that reset the filename. Five steps in the software determines whether there are duplicate files in the destination folder. In order, these are: Does the folder structure exist? Is there a file with the same name? Is its size identical? Do the creation dates match? Do the modification dates match? So the checks are thorough, but in some circumstances the incremental backups do not work.
