recommend BACKUP software-just revised files

[DerickH]

I'm looking for backup software that will backup only my revised files files to a target external drive. I don't want to copy over files that haven't been changed. Is there a simple programs that doesn't require much interventioned. I don't want the files that haven't be changed to be copied over. Are there any freebies out there?

Windows built-in backup will do it for you:

The Windows Backup (Microsoft Backup) program supports five methods of backing up data on your computer or network.

    * Copy backup. A copy backup copies all selected files but does not mark each file as having been backed up (in other words, the archive attribute is not cleared). Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations.
    * Daily backup. A daily backup copies all selected files that have been modified the day the daily backup is performed. The backed-up files are not marked as having been backed up (in other words, the archive attribute is not cleared).
    * Differential backup. A differential backup copies files created or changed since the last normal or incremental backup. It does not mark files as having been backed up (in other words, the archive attribute is not cleared). If you are performing a combination of normal and differential backups, restoring files and folders requires that you have the last normal as well as the last differential backup.
    * Incremental backup. An incremental backup backs up only those files created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared). If you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets in order to restore your data.
    * Normal backup. A normal backup copies all selected files and marks each file as having been backed up (in other words, the archive attribute is cleared). With normal backups, you need only the most recent copy of the backup file or tape to restore all of the files. You usually perform a normal backup the first time you create a backup set.
