Failed Backup

I/O error is generally a driver or firmware error

Make sure that you are current onm both for your SCSI Card, your tape device, and (if you have one) for your library


If you are runnong AOFO, see http://seer.support.veritas.com/docs/268416.htm

Hi,

I/O errors occur also due to delays in communication between the tape device and Backup Exec.

1. http://support.veritas.com/docs/191158 is very helpful to check the settings on your SCSI Controller.

2. Its recommended to not attach the tape device to a RAID Controller, except for tape devices that are certified by the OEM's to be compatible with RAID Controllers. Use a separate SCSI Controller for your tape device.

Additional tip:

You might want to check if there are any hard/soft write or read errors on the media -- click on Media in Backup Exec > Select a media that was used for a backup which failed & view Media Statistics down below in that window. Hard errors may mean that the media is bad. You can try a new tape. Also clean the drive 3-4 times consecutively.

Have a nice day!
