I have Backup & Restore set to auto backup my data files (including my libraries) on a daily basis. From my understanding, the backups only include items that have changed since the previous backup. However, Backup & Restore is creating new copies of my Music folder on the backup drive each day (and therefore taking up a lot of space). Nothing has changed in my Music folder...it's been static for pretty much a year...nothing added or deleted.

Has anyone else come across this issues?
