Scheduled Export works the same way. A example of a way that scheduled export could prove useful is if one scheduled the daily export of customers, which would allow integration with a CRM, that could be updated daily without having to manually export data.
To start with, go to
System -> Import/Export -> Scheduled Import/Export
You will see two options, one to schedule the import and the other for exports. You can either import customer data or product data. The file should be in .CSV format.
Here is a sample Import.
Note: Server type can be defined to RemoteFTP meaning that it can import the file from a different server.

For export, you will notice the ability to skip based off of certain attributes. Here I chose to skip all products that cost between $1 and $10.
