Anyone able to use Win7 for backups?

I cannot use Win7 to back up my drive. I receive the following error

Error: 0x8078002A occurs when backing up....


Anyone get this?

My external drive is a Seagate GoFlex 3TB drive using the included USB3.0 cable. My C drive is below is an Intel SSD in my sig.

I'd appreciate some insight here. I'd prefer to use windows to do the back ups because I don't want to buy Ghost or Acronis (heard current version of Acronis has issues), and I'm not backing up to the "cloud"!

Thanks in advance.

have you tried allwaysync (free)? a little weird to configure but i use it exclusively for all my clients.
