Invalid File Header Signature

[wildek]

Hi,

Every night I back up using Brightstor 9 on a server running windows server 2000 SP3. I am using Maxell DLT 40/80 tapes. The media is overwritten/formatted nightly before the backup.

The job status shows the backup as complete and finished. When I look in the Activity log, I see a ton of Invalid File Header Signature (E3802) and Invalid File Signature (E3803) errors.

Does anyone have any idea what this could be caused by? I do have verification turned on and it seems to happen during the verification process. It will list a warning saying file contents are changed, then it will list E3802 and E3803 and this trend will continue almost until the end of the verification process in which I no longer get the file contents changed warnings, just a number of E3803 and E3802 errors in a row. I also tried cleaning the drive like Arcserve says to do in the help file.

I did try a restore by session and restored files fine. Is this something to worry about or are the errors a result of the verification?

Thanks,
Ken

It is something to worry about.

You did a test restore good. But did you restore the same files that got the errors? If not try it.

Check to see if it is the same files each time that get the errors.
