I set up a backup routine, using the wizard on Nero 6 BackItUp, trying to back up several files from my desktop computer's hard drive to an external hard drive. I was using compression & doing a full backup. The next thing I noticed was a lot of little icons appearing in my lower tray, on the right, which I ignored. Then, the next thing I noticed, several hours later, is that the routine was still grinding away, and was trying to do EIGHT backups simultaneously. Eight identical sets of files were being written to the external hard drive, and my drive was almost full when I finally got the program to stop grinding away. Does anyone know what might have caused this to happen? I'd like to know... After I deleted everything, I re-did the wizard, without compression this time & ran the program, & so far it's working fine. Why would it do what it did the first time, making duplicate backups on it's own volition? Is this something that Nero BackItUp is known to do? Thanks for any input on this.
