Which set of small and large data backup methods are available in native Salesforce

The term 'Mass Exports' is ambiguous, and 'Data Loader Exports' refers to a tool rather than a distinct native backup method in the context of this question.

This option includes 'Data Loader Exports,' which is a tool used for exports rather than a specific 'method' name like 'Weekly Data Export Service' or 'Report Exports.'

The Weekly Data Export Service is a native, scheduled method for exporting all of an organization's data for large backups. Report Exports allow users to extract specific datasets from individual reports, suitable for targeted data backups. Furthermore, users can export the underlying data from report components displayed on a dashboard, effectively using 'Dashboard Exports' as another mechanism for obtaining specific data for backup.

The 'Mass Export Wizard' and 'Data Loader Exports Calculator' are not standard native Salesforce features for data backup.
