How to write a script to reset a site?

Question

bash

A separate backup/ directory contains a database dump and a folder with the site's source files (images).
You need to do the following via cron once a day:
1) delete files from the /files folder
2) wait until all files are deleted, then proceed to the next step
3) copy the files to the /files folder from /backup/files
4) delete the tables from databases
5) wait for the tables to be deleted, then go to the next step
6) roll the database dump
