Sense an external hard drive is just like a normal one, any backup software you want, even the one built into windows, should work. However, some special features like one-step backup might not be available, as they would be with the normal software.
Ok, thanks for the answer. I suppose I should try the software that is included with the external hard drive I end up buying and see how I like it. Does anyone here have any experience using the software included with WD Passport or Seagate FreeAgent Go? In addition, I am gathering from what I have read on these forums, that if I want to backup the operating system and program files, I may want to use an imaging program like Norton Ghost or Acronis rather than regular, incremental backup software. Is this correct? And can I back up both the operating system and my incremental, document backups to the same external hard drive, using different backup programs, as long as he hard drive is big enough? Initially I was expecting that I could buy an external hard drive and easily backup my entire internal hard drive weekly or on some frequent schedule, so that if the internal drive in my laptop ever crashed, I had a complete copy of the internal hard drive on an external hard drive, but perhaps this is not so easy or adviseable? Perhaps I should expect to backup the operating system and program files once with a program like Ghost, and then do the docs and other stuff incrementally with one of the programs that comes with the external disk?
