No Option to Backup AppData folder under User Account RRS feed

  • Question

  • I recently setup a new Folder Pair to backup the entire contents of my User Account folder to an external drive. Included under my User Account folder is a folder called AppData, but I noticed that this folder wasn't being backed up by SyncToy. Also when I try to browse within SyncToy to find this folder it doesn't appear. That is, I can see all the other folders under my User Folder, but I can't see the AppData Folder.

    Is there any reason why SyncToy won't allow me to backup this folder?

    I am using SyncToy 2.1 with Vista Business.

    Thanks in advance.

  • Hi Casho,

    I do not have a Vista Business environment, so I tried your scenario with Vista Enterprise instead. On my machine, SyncToy 2.1 synced the contents in App Data folder as expected. I think you can check the following things that may cause your problem:
     1. The “App Data” folder is a hidden folder. So please make sure the “Exclude hidden files” and the “Exclude system files” have been disabled.
     2. SyncToy may need enough permission to access the “App Data” folder. So try if running SyncToy as Administrator can resolve your issue.

    And please note that there is a known issue of SyncToy 2.0/2.1 that it cannot sync any file which is being used by other programs. A runtime error like “Error: Cannot read from the source file xxx. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)” will be raised if SyncToy tries to sync such files. The problem is there are such files in “App Data” folder.
    Another issue of “App Data” folder is some applications work well only with the data files created by themselves. So the x-copied data files may cause problem.

    Thus it is not recommended to Sync the entire App Data folder. It would be better if you only sync the sub folders you need in it. You can approach this by “setting subfolders” section in “Change Options” window.

    Thanks

  • Hi JiGuang,

    Thank-you so much for your help.

    You steered me in the right direction. The problem was that in Windows Explorer I had selected to "Do not show hidden files and folders". Now that I have changed this, I can see that the AppData folder has actually been backed up by SyncToy. The reason that I didn't suspect this originally was that when I was viewing my User Account Folder in Windows Explorer the AppData file was visible. It just didn't show up in the Browsing Pane within SyncToy. Know it is visible in both.

    Thanks again.
