When you install the program, you will see an installation menu that prompts you to import data from a backup. Accordingly, you must agree to this action and find the file you want to upload to the program.
It's good that you managed to save a backup of your data. One day a friend of mine had a similar situation, and he had to contact HARD DRIVE RECOVERY to recover data.
This can be done independently using the program; however, all data will be deleted and will not be recoverable if an error occurs. It is better to consult a specialist.
