How to backup data in strapi on SQLite database

thanks sir for replying back.
I deleted the model from an api but the server sitll doesn’t start.
you mentioned to rebuilt it but I can’t without having the server to be open.
I am stuck now, I really need help
I recently created a repo and commited it on github just for people to have an access.
please I need help.
it is a best project of my portfolio, it took six months to build it and I can’t start from scratch.
I have been struggling with issue.
I look forward to hearing from you back
