If you try to save any of your large Site as Template, you might get the following error
"The site is too large to save as a template. The size of a template cannot exceed 10485760 bytes. "
This can be solved by just increasing the maximum size of the Template
stsadm -o setproperty -propertyname max-template-document-size -propertyvalue 20971520
Note: 20971520 bytes = 20 MB, Maximum Size you can set is 500 MB
