Hard Drives - external hard drives posted in the Hardware forums; I appreciate the input still not comfortable with wifes pic on external. may have to back up on disc for peace of mind....
Well, if you want a safe backup (next to the external), you can take DVD(- or +)RW and update it often.
But this disc could also get damaged so as you'll see you can never get a 100% safe backup.
Thus, I would recommend a external and if you like a DVDRW. One of them or both together is safe enough...
