Synchronize Your Data with Self-Service Background Encryption
Where: This change applies to Salesforce Classic and Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions.
How: To synchronize your data, go to the Encryption Statistics page in Setup.
You can also encrypt field history and feed tracking changes when you synchronize your data from Setup. On the Advanced Settings page, turn on Encrypt Field History and Feed Tracking Values. Now whenever you sync data from Setup, field history and feed tracking values are also encrypted by your active key material.
Self-service background encryption isn’t available for all data elements. You can’t sync standard description fields, long and rich text area fields, and data elements, such as files and attachments, and Chatter data through Setup. For help synchronizing this data, contact Salesforce Customer Support. You can also request that Salesforce Customer Support encrypt field history and feed tracking values.
