Python, sqlite -Any backup methods that include the index as well as the indexes table?

Question

I see by this question - http://stackoverflow.com/questions/4019081/copy-a-sqlite-table-from-a-disk-database-to-a-memory-database-in-python - that sqlite tables can be transferred from one database to another. I was wondering though, do Any of those methods also copy the index,can they be modified to copy the index, and are there any other methods to backing up?
