I use the Seagate 2Tb as a backup drive although I found the software caused severe audio latency when I had it set to continual backup (possibly because it's designed for a USB3 and I only have USB2). I use the Easus free backup now. I prefer this as you can access the actual files via explorer. My first Seagate backup drive died after two weeks (nasty clicking sound) but this one appears healthy enough. I also have most of my important files copied to other external HDDs too (plus copies of copies so if one goes, everything should be on the other).Just buy a HDD bigger that the one in the PC and copy everything over.
