how best to completely replicate a db file?

I think I could manually perform all the steps but I was curious to know if there is a semi-automated way to regenerate a database from a schema and a set of exported data files.
I have a case where I can't physically access the db file easily but can programmatically. For security I can download the file but I can't upload a replacement. So I'd like a scripted solution that I could use to regenerate a db file from scratch and then populate the tables with data that I know is accurate.
If there is a handy utility that takes care of the grunt work or a site that describes the steps I'd appreciate any pointers.

You might consider the CLI shell's .dump command to be that handy utility.

Wow thanks. I saw a .dump file mentioned in a message but didn't know what created it. Given the description of the utility I assume it can handle the orderly creation of indexes and such (I don't have any on this file) if they exist?
I believe you have solved my issue!

You can also use
VACUUM INTO 'file.db'; to create a backup since 3.27. That's what I use. If not available, I use the Online Backup API. Before that I had to resort to making a file copy after starting an exclusive transaction.
