You can create a data masking policy for Salesforce data. A data-masking policy contains a set of Salesforce objects and fields to mask and the masking strategy to use to mask the data. The data masking strategies depend on the data type. For example, if the data type is "date", then you can use the shuffling masking type. For easier management, use separate data-masking policies for each backup set.
Caution: The changes that data masking makes to the data are irreversible and might destroy the data. Data masking is intended for restoring production data to a sandbox.
