Windows7 Backup Error Code 0x810000FF

From the Helpful Error Codes-dept.

I am using Windows 7 at the time, and it's set up to backup some "important" files to an external hard drive on a regular basis. The other day, Windows kept telling me that the backup failed, giving the helpful error code 0x810000FF. Google did not provide any real help on this. I did notice, however, that I was low on disk space on one of my partitions included in the backup (not the target drive, nor the system partition). Freeing up a couple of GBs did the trick. So maybe the error code should be "insufficient disk space" or something. But then again, hex looks cooler.
