    I have a problem with backups failing with the following error:
    "The media family on device '%ls' is incorrectly formed"

    I have tried the following:http://support.microsoft.com/kb/297104

    But it did not help, and the log file is smaller than 4G.

    Is there anything else that could cause this problem?

    Do you have certain disk quota enabled on that Windows server?

    You get this error when the database backup running and job failed due to network issue or destination server reboot which result incomplete backup...
    When you restart the backup job it can't overwrite eventhough you have WITH INIT option in your command...

    To resolve this simply delete the file before running the backup using xp-cmdshell then run the backup...
