The backup file contains unrecognized data and cannot be used

    We have just experienced a hard disk crash and I am trying to recover the
    lost data. To my horror when I tried to do the restore I received the message
    listed above when I try to perform the restore.

    I'm running SBS 2003 SP1. The version of NTBackup is 5.2.3790.1830. I can
    catalog the file OK. The backup file is on a hard drive in another part of
    the building rather than on tape. I've looked at the newsgroups for words of
    wisdom and most of the comments reference trying to access the file with a
    different OS that it was created with, this was not the case.

    I have looked at other bkf files that have been recently created and there
    all experience the same problem so I don't think it is a simple disk
    corruption I'm thinking more of a software issue but I have been wrong
    before.

    Any words of wisdom would be welcome.

    Thanks

    What's the point of a full system backup if you have to spend hours
    reinstalling the base stuff and patches before restoring, in the hope that
    *maybe* you did it just right and restore will be possible?

    Just wondering. Actually, still wondering whether SBS is worth the risks to
    a small business.

    Thanks for the response Mev, No, The disk that went was my D: drive so I did
    not to restore my OS. The version of NTBackup that created the file was the
    same that as the one I am using for the restore.

    I have included the log file of the backup job in case it may shed some
    light on things. Note that it VERIFIED fine!!!

    Well, it's not supposed to be a guessing game - one should always do test
    restores periodically, and do a test disaster recovery restore to make sure
    one knows how. Third party backup software can also allow one to do a 'bare
    metal' restore.
    As opposed to what? Any system can have problems. And hardware can fail.
    Much depends on the quality of the hardware, the skillset of the people who
    set it up, etc.

  6. Is there any way you can copy the backup file (Small Business Server Backup
    (01).bkf) to your server, or an external drive attached to your server, and
    then try to restore it from there? I'm thinking maybe a mapping,
    permissions or ownership problem.

    Thanks Merv, I tried copying the files to a local disk on the server, but I
    wasn't able to select the file, very wierd, I browsed from the ntbackup,
    selected the file and hit next, the response was that no file was selected.

    Not being put off I changed the permissions of the directory, and the files
    on my remote backup disk where the backup files resided, to all for everyone.
    Retried the backup procedure and received the same message as I originally
    posted.

    Could I be using an incorrect/old ntbackup version? I'm currently running
    5.2.3790.1830.

  8. The version of NTbackup is correct for Windows 2003 SP1. Can you log onto
    the workstation that contains the backup files (as a domain admin) and push
    (copy) the "(01) backup file" to the server?

    On the (01) backup file, make sure the Backup Operators group,
    Administrators group and System all have Full Control in the Security
    permissions tab. Maybe even add Domains Admin group with Full Control. You
    may even want to check ownership on the Backup folder and have your domain
    admin account "take ownership" of it.

    Also, in the Restore and Manage Media tab in NTBackup, before you attempt to
    select the target file, can you catalog the (01) backup file, then proceed
    with the restore? (Tools | Catalog a backup file)

    You might also try mapping \\Homedesk2\BigDisk (F)\Backup Files to
    your server and then try to access it as a drive letter.

    You might also try adding your user account to the Backup Operators Security
    Group on the server.

    And try logging into the server console for the restore (not through a
    remote desktop session).

    OK - what you suggested worked! I have managed to restore my exchange
    directory and the users directory back to their previous positions. I had to
    go back to a previous days backup but I am still claiming (a sort of victory).

    I have a couple of follow up questions: I am getting a C1041724 error
    message when I try and restart the mailbox store. I'm seaching the net for
    possible answers as I type. Also I need to remount my users directory to
    <server>/users. Do I just set up a share and if so what permissions. Sorry
    for the stupid question but I feel my brain has turned to jelly with some
    serious lack of sleep :)

    Thanks

    Thanks Chad,I went out and purchased a new drive and am restoring the data
    onto that. I have mounted the bad one on another computer and I am to restore
    the files that way as well. I went a purchased Restorer 2000 which seems to
    get some of the files but it is VERY slow. Have you had any success with the
    s/w you provided in the link?

    Wondering

  11. Hi Martin,

    1) Which part(s) of what I suggested fixed the problem?

    2) And maybe this will help with the Exchange problem...

    Mounting a Database After Restore Fails with Error Message c1041724
    http://support.microsoft.com/default.aspx?scid=kb;[LN];Q253931

    3) User Folders

    Hmmm.. the backup should have recreated the "User Shared Folder" for you
    (along with it's permissions). If not, here's a link with the defaults:

    Default User Shared Folder permissions...

    Thanks Merv, I am back up and running - I let ntbackup do the restore of
    exchange and everything came up fine after that. I'm still in shock of the
    data that I lost. I am using other tools to try recover them from the faulty
    disk.

    So that I can try and prevent this happening again, what should be the
    permissions on the backup directory on the other computer that I'm writing my
    backups to?

    Thanks again

  13. On the external USB drive attached to my SBS, I have SYSTEM and
    ADMINISTRATORS with "Full" permissions. You may even want to add the Backup
    Operators group with Full permissions.
