Salesforce's Data Export Service is a tool that allows you to export your organization's data to a set of comma-separated values (CSV) files and store them in a backup location of your choice. You can schedule this service to run weekly or monthly and receive an email notification when your files are ready to download.
This is one way to back up your data daily without using any external tools or services. References:
