Some really great advice so far. One thing that many people do not think about is future compatibility. Many back-up programs use their own compression algorithms, to save drive space. If the company goes out of business or when new operating systems are introduced, there is no guarantee that your backup software or the back-up files will be readable. That is why I use Microsoft 'Synchtoy' for backing up my image files. This program was written specifically for photographers & is free. It uses no compression, so your back-up files are identical to the originals. Of course, this means that your back-ups will require more drive space than compressed back-ups, but HDs are getting cheaper ...

Most archival software will allow you to select no compression, but what you're really talking about here is file based backups (ie, file by file, not into one big tarball).  Synctoy is just Microsoft's incantation of the long lived rsync product which was written in the 90s in unix land.  Nothing to do with photogs.

Since jpegs and raw and even tiff are largely incompressible, you wouldn't want them compressed anyway.  The obvious gain from a file based copy is that you can easily examine the backup side, rather than have to restore the entire set or a portion of it first.

CNYC - your solution seems to have 3 drives all attached to your computer, either internally or via USB.  This will not protect you against theft or fire.  You need to figure out how to keep one set offsite.
