Incremental Backup Problem
There has been ongoing debate on Microsoft's TechNet site about an issue with Windows 7 RTM x64 and incremental backups. It seems as though Windows 7 x64 is not performing incremental backups as it should by design. Per Microsoft Help: "After you create your first backup Windows Backup will add new or changed information to your subsequent backups ... Windows Backup keeps track of the files that have been added or modified since your last backup and then updates the existing backup, which saves disk space." In other words, after a full backup, Windows 7 should only back up changed data.
Except that isn't happening, according to many users on TechNet and reviewers' findings in the CRN Test Center. Win7 x64 is backing up the entire system again and again, eating up tons of disk space and extending backup jobs that should take a few minutes into hours.
To date, there is no satisfactory explanation from a Microsoft engineer or TechNet as to why this is happening, only lots of posts from frustrated users. Users are especially ticked off because the feature worked fine in Vista.
