Backupexec capacity licencing

Just a really stupid question

 

im looking at capacity licencing, if we backup

 

1.5 TB File data per day (data expires 2 weeks) > disk > tape

1TB Exchange per day (data expires 2 weeks) > Tape

1TB SQL Data per day (data expires 2 weeks) > Disk > Tape

 

would we need 4TB Capacity licence?
