ultimate backup error: file already exists

    I'm trying to back up from Vista Ultimate to a share on a networked
    Linksys NSLU2 I named NAS1. The share is 'backup'. Backup can browse
    to the folder at which point I get a userid/pw prompt. After
    completing login to NAS1, Vista backup consistently fails because
    "Cannot create a file when that file already exists. (0x80070087)".

    When I look in the share directory, there's a new subdirectory with
    long hexadecimal name. It wasn't there before I started backup, so
    backup created it then wants to try to created it again?

    Any suggestions for resolution?

    TIA

  2. This is indeed a reason why backing up to mapped drives isn't supported
    with Windows Vista.

    According to Microsoft, to use a NAS device as a backup target, you
    need to create the share with "Full Control" privileges for the user whose
    credentials they want to connect with.

    If this doesn't work, contact your NAS manufacturer to ask them for
    upgraded firmware based on 3.x version of Samba.

    The account in question is adminstrator on the NAS. Why would that not
    work?

    If it matters, I didn't use a mapped drive letter. I used UNC,
    \\NAS1\BACKUP.

  4. Some other users have reported problems that turned out to be Samba bugs. In
    terms of troubleshooting you could try to use a subfolder under the share
    and see if that works. If it doesn't, sometimes a firmware update is what is
    needed to have this device behave as expected. The more recent Samba
    versions (3.0.2.x) are more stable.
