Informix - dbaccess vs dbexport to export tables to text files

Currently, we are using the **dbaccess** utility to export all tables in the Informix database to text files. These are used to "mirror" the database multiple Windows machines running MSSQL Server on a nightly basis. I was looking into the **dbexport** utility to see if it would be a viable solution. The text export takes almost 2 hours and I'm looking to shrink that time down if possible. However, I'm not familiar with these Informix utilities and we do not have a test environment for this... so I'm wondering what exactly is the output from dbexport? Is there an option to export each individual table to a text file with dbexport? Thank you.
