    It's not a NAS device as such, but a dedicated Linux PC, so I load
    whatever version of SAMBA I wish.

    I have tried the latest 2.0.34, and it still does not work, and I am
    pretty sure it's a Vista issue, rather than a SAMBA issue, as I should
    be able to backup to any network server I wish, regardless of server

    Seriosuly how tricky would it be, so that if the logon and password
    credentials are blank, to not store the credentials. The point is, I
    can access the network shares perfectly in explorer.

  2. The latest Samba is 3.x.x:
    http://us3.samba.org/samba/history/samba-3.0.24.html. Backup must be able to
    not only read/write/delete files but also set ACLs on them. We must protect
    the backup file, and to do this, the SAMBA version must support this. If
    there are bugs or other issues in the SAMBA code that don't allow us to set
    ACLs, then we can't use that share as a target.

    Give the latest version a try and see if that helps.

    Sorry, typo on my part, I am running Samba Version 3.0.24

  4. On your Linux server, you need to create an account that is not root and
    allow it full access (meaning read, write and most important change ACLs,
    sometimes called all access) on the share and on the files.

    Unfortunately I don't have instructions for doing this. NAS boxes usually
    have a web UI that you can use.

    When you can perform the following steps successfully from the command line,
    then Backup should be able to use it as a target:

    - net use with the account against the share
    - create a file on the share and put some small data in it
    - the owner of the file should be user used in net use
    - change the ACL of the file using cacls.exe
    - delete the file
    - create a directory on the share
    - the owner of the file should be user used in net use
    - change the ACL of the directory using cacls.exe
    - delete the directory

    Backup does this programmatically to determine whether the account has the
    necessary access.

    Update re- my previous post. I checked the firmware specifications fo
    the Linksys/Cisco NSLU2 firmware V2.3R63 which I am using. Apprently
    it is using Samba 3.0.11

    I'm curious what NAS devices Microsoft actually tested, seeing as ho
    Linksys/Cisco is probably one of the more common ones. Perhaps
    listing of tested/supported NAS devices that Microsoft knows work
    would be educational

    I'm having this same problem; however I'm using a Maxtor 1TB Shared Storage
    II NAS drive. It is at the latest firmware from Maxtor 3.1.26 and I cannot
    see any indications as to whether it is SAMBA or not.

    Has anyone successfully backed up to the Maxtor Shared Storage II drives?

    Cannot create a file when that file already exists.

    Just found the answer! Use the username everyone and your admin password
    for your NAS device. Everything works after that... I'm using Vista x64
    and a WD Mybookworld NAS.
