"Your computer has been restored to an earlier point in time"
I've been using Windows 7's Backup and Restore to back up the 500-GB hard drive on my laptop. The hard drive has about 290 GB of data on it; I'm backing up onto an otherwise blank 1-TB USB external drive. The first backup took ~1-2 days, and used about 400 GB. The next couple of weekly backups were much faster (less than an hour or two).
When I ran Backup yesterday, it took more than a day to complete. When it finished, it displayed the message, "Check backup settings - Your computer has been restored to an earlier point in time. As a result, your backup settings might be out of date." It gives a backup size of 762 GB. At most I've only added a few GB of data to my hard drive each week.
Any ideas on what would cause this? I have never (knowingly) restored this hard drive from a backup, nor have I used System Restore on this computer.
On a Microsoft site it was suggested that I run "sfc /scannow". When I did so, it went through the verification phase of the scan, reported "Windows Resource Protection did not find any integrity violations," then exited. Would this imply that the Backup and Restore behavior is not caused by issues that sfc scan would address?
