It doesn't: it reads them sequentially.

Somehow, you need to be able to create a "snapshot" of your database 
files so that they are entirely self-consistant before they get backed 
up.  This depends on your database.  What kind of database and database 
program are you using?

If you're using linux lvm or evms, you can stop your database, create a 
snapshot, restart your database, and back up the snapshot of the 
database files while the database continues running.  This may or may 
not be acceptable for your enviroment.
