Hello all, I am using windows 7 backup weekly. I have selected certain user folders (with files) and folders/files on an external drive to backup. I also have selected to only keep newest system image. After a few weeks my backup fills my backup hard drive. It appears that the size of the backup is increasing by a significant amount of gigs per backup. Even when I delete or have less files than the week prior the size keeps increasing. About once a month I have to delete/format the drive and start the backup all over. How come the backup size keeps increasing?

Hi, Windows Media Player Networking Service will refresh the date of the files’ status every day. It is a known bug. You may try to install SP1 for a test. Also, to disable Windows Media Player Networking Service is a choice.

Mr. Chou, I am running SP1 and I still have the issue. I have disabled disable Windows Media Player Networking Service. Hopefully that works. Thanks for your reply.

I had the same issue with the regular backup settings in win7, I ultimately chose to use the system image backup instead and run it once a week (overwriting the previous backup "assuming all is working properly" and I haven't done a windows update within the last 7 days). I also noticed at one point that something had activated virtual PC even though I had not touched it, this forced my personal windows user profile to start seriously bloating, what I found was windows had created a virtual c:\ drive within the profile and loaded the system and my profile within it. I found this under USERS\*YOURNAME*\APPDATA\LOCAL\ Since I've done a reinstall since this happened I can't be sure of the rest of the path from this point BUT it is clearly listed as VIRTUAL PC (it may have been within the Microsoft directory and can be deleted without any issues, assuming your not running any virtual software). Hope this was helpful I forgot to mention you may want to delete everything in the temp folder located in LOCAL also since it just gets larger and larger till you do delete it (not sure if disk cleanup utility does this directory, I just do it manually).
