Some times you need to take the backup of your subsites with all pages, list and library. Subsites can not be taken as backup and restore. Subsite can be exported and imported to another site.
First you need to export the subsite. So to do that Go to central admin, Click on backup and restore, then “Export a site or list” as shown in below screen.

Then select your site collection, after that select your subsite and give a file name for ex- musubsiteexport. Leave other things as usual and click on start export and wait for completion.
