Backing up Archived files

[rookie]

Hi,

When we perform a full backup I select for all contents within the folder to be backed up onto tape.  The full backup completes succesfully with no errors.  However, when i check the folder of the full backup for restore only 2 out of 12 of the files are there.  This is a full back up, the missing files are database files that are flagged with attributes as archived.  How can I resolve this issue and be able to successfully back these files up onto tape. 

Thanks.
