You can view the changes made to the data or the metadata in a Salesforce organization by comparing Salesforce backups.
The Metallic software offers the following comparison types:
Object comparison: View the added, deleted, and modified records for an object between two backup times.
Metadata comparison: View the file differences for the Salesforce metadata, such as layouts, Apex code, and workflows between two different backup times. You can also compare two Salesforce organizations to one another.
