There are a number of vendors on the AppExchange that will happily sell you a solution to do this.
Full-scale data and metadata backup is not a built-in capability of Salesforce. If you'd like to do it yourself, you would be looking at combining the native Weekly Data Export feature with a regular process to extract all of the metadata from your org using, most likely, an IDE or a Metadata API client like Salesforce DX or the Force.com CLI.
Even using a purpose-built tool, backup and recovery is never a simple push-button operation, and backups lose a lot of their value if you do not have a detailed and rehearsed incident recovery plan in place.
To backup all metadata from a Salesforce Org, you may also explore this: https://github.com/itlibrary/salesforce-metadata-backup
Make sure you list all the desired metadata types in build.properties. Many of them are already mentioned there for easy reference.
