Home Forums SQL Server 2005 Backups Backup Log Incorrect Function Message (nonrecoverable I/O error). RE: Backup Log Incorrect Function Message (nonrecoverable I/O error).

  • Gail,

    Thanks for the response! I am worried that a restore may be in order, but that usually takes 2-3 days, due to the size of the database (853 GB for the mdf file, 187 GB for the ldf). Full backups are done weekly and log backups daily.

    I did try to copy the ldf to a different drive (after doing another full backup). The copy was almost complete, then I received an "Invalid MS-DOS function" error message. *SIGH*

    At this point, looks like a restore will be in order (tomorrow, when my head clears more!).

    FYI, there were no errors in the event logs, other than the application error about the backup failing.

    Hey... on the plus side.... this is the first time we have an this type of error! 🙂
