  1. Re: Difference encountered in file data.

    Veritas DOES NOT compare tape data to disk data on verify. It recalulates
    and compares checksums. What this message means is that the tape data
    itself is corrupt

    Even AOFO is not designed to be used with Database files.

  2. Difference encountered in file data.


    Is there any way to keep a job from failing when a difference is encountered
    in file data? I'm currently running Veritas Backup Exec 9.0 (Build 4454)
    on a Windows 2000 Server with the Open File Agent. It seems to be backing
    up the open database files without any issues, but since the database files
    are always in use and always changing the differences in the file data are
    expected.

    Here is a copy of the log file :

    What is one supposed to use to backup these open files then?? What is
    the intended purpose of the AOFO option??

    Open non-database files.

    To safely backup databases, you need an appropriate agent for hot backups,
    or to shutdown the database to a cold backup.
