Hoan,
The log files keep data that is written into the PRIV.EDB database,
until the database is fully backed up. The idea of keeping the log data
is, in case your PRIV.EDB file crashes or gets corrupted, you can
restore the last full backup of PRIV.Edb, and play back all the data
from the log files. This way you will roll forward your PRIV.EDB up to
the point when your PRIV.Edb crashed. In other words virtually you don't
loose any data in your Information store. When you enable circular
logging, some of these log files may be over written before a full
backup is done. When this happens, when you restore the last full
backup, you loose all data in the over written log files. The users will
find data missing.


Regards,

Raj

Hi Mark,

I have an EX 5.5 with circular logging enable, a full backup is perform
on the daily basis except Sunday. Will I runing to the risk of losing
data if I perform a restore? 

Thanks,
Hoan Le

I would strongly suggest no one enable circular logging on their 
Exchange server, you run the risk of losing a whole lot of data if 
you need to perform a restore.
