Setup Script: Backup Feature for the .env file.

[palisadoes]

Is your feature request related to a problem? Please describe.

If someone makes a configuration mistake with the configuration script there isn't an easy way to recover.

Describe the solution you'd like

1. At the very end of the setup script. Prompt to backup the old version of the file.
2. If the user decides to do so:
   1. Save the old version in a .backup/ directory
   2. Name the file .env.EPOCHTIMESTAMP where EPOCHTIMESTAMP is the UTC epoch timestamp in seconds
   3. Let the user know the name of the file that it is saved as
3. Tests need to be written for this and they must be valid.

Describe alternatives you've considered

Approach to be followed (optional)

• See above

Additional context
