Recommened actions for status code 90 is here. http://www.symantec.com/docs/HOWTO50864 Detail steps of enabling debug logging is described in Troubleshooting Guide. http://www.symantec.com/docs/DOC3683 Also check Backup Exec CPS agent or some other applications(anti-virus or so) that blocks I/O is installed. http://www.symantec.com/docs/TECH143366

Have entire drive letters been added to Exclude List?

If so, add * to the path, e.g. X:\*

See http://www.symantec.com/docs/TECH125205 for details.
