Backup to SAMBA, SBS backup Wizard fails, NTbackup.exe works

    I am trying to configure my SBS server to back up to a SAMBA server.

    If I run ntbackup.exe and back up to the same server, it works.

    If I use the backup wizard and then try to run a backup, it fails.

    Why is this? Is there any advantage to using the backup wizard, if I can
    schedule a backup in NTbackup.exe?

  2. As Supergumby mentioned, the SBS_backup_user is enabled by SBSBackup prior
    to the backup, and disabled after it's done. So that account needs access to
    the share. If you look at your event logs carefully, you'll see it
    happening. If the Samba box has security logging, you'll likely also see
    access denied when the SBSBackup runs.

  3. Depends, SuperG. Yes, only that user needs it. BUT, it can't be done as a
    drive letter, I believe. It has to be done to a UNC, correct?

    I increased the log level and see that the user name used by the server is
    actually "SBS Backup User" (note the spaces, rather than underscores). How
    do I configure things on the SBS server so that this user has the password
    required to access the share?

    Can you configure the Samba server to use Windows authentication via AD?. If
    you can't you may be out of luck.

    While I am looking at those links, does anyone have an answer to my other
    question: what advantage is there in using the SBS Backup rather than just
    using NTbackup.exe directly and scheduling backups through NTbackup.exe?

    SBS Backup knows all the ins and outs of SBS and is supported by Microsoft
    for a bare metal restore solution. In other words if you have a problem you
    can phone for support. It may cost you but the support is there.

    Support I can understand, but does it do anything special with the backup?
    For example, Does it export the user data in some format that makes it
    easier to restore on another server before backing it up?

  9. The main advantages of SBS backup vs some other strategy (IMHO)

    Integration to server monitoring, I get an email from my SBS every morning,
    one of the early items in it is 'Backup: Completed successfully'.
    Unless you customise it it is difficult to use SBS Backup and lose
    information. The backup wiz will not allow any shared folders to be excluded
    from the backup, it includes the OS, System State, and Exchange, and though
    I prefer to maintain SQL/WMSDE/MSDE backup through SQL's own mechanisms
    Windows shadow copy _should_ get these back from a wiz based backup.
