What backup program are you using?
Are these Exchange logs?

if they are excnage logs make sure you are using a exchange aware backup program and doing a full backup of the database. Once you do a full backup of the database with a exchange aware backup program it will flush all the logs.

Did you use the SBS backup? If you use the full SBS backup from the SBS console it should clear those logs and deleted mail items. If you use the manual Windows Backup tool it may not depending on the selections you made.

Yes used the sbs backup.... If the database file priv*.mdb gets backed up can't I just delete those file manually?

The location is c:/program files/Microsoft/exchange.../mailbox/first storage group

You need to make sure the log files are written to the database or you can loose or corrupt data.
I would try another backup. Others may have more 'efficient' solutions.

actually I have had multiple backups.  Upon further investigation I have found that the backup did report errors in that "exchange may not be restored .....consistency check failed for component Microsoft Exchange Server...."

"consistency check failed " may indicate you still have a problem with the Exchange database". See how the next backup goes.
Cheers!

Found solution through a little surfing.  Simpler than most people thought.  Log files are not necessary except in the instance of db recovery.  Knowing how to safeguard that data is very important.  A full backup negates the necessity for prior log files.  When IS is mounted it creates base level log files.

Thanks to those who tried...
