Problem:

When two or more Oracle Databases are backed up to a Backup Exec Deduplication Storage Folder during the same job the backup set is corrupted and a restore from the set fails.  This will go unnoticed if Verify is disabled during the Backup Job.  If Verify is selected for the backup, the operation will fail and indicate that there is a problem with the backup.  Duplicate Jobs will also fail from this backup set.
