Overview

Salesforce does not support restoring either standard history objects or approval history. Both are intentionally designed as immutable audit trails and are restricted by Salesforce APIs to read-only access. This ensures the integrity of audit data but also means that history records cannot be recreated or restored once removed.

Standard history objects 

Examples: AccountHistory, OpportunityHistory, CaseHistory

• Not supported: Insert or update operations
• Result: These objects cannot be restored once removed

Salesforce references: 

• EntityHistory Object (API Reference)
• Associated History Objects

Approval history objects 

Examples: ProcessInstance, ProcessInstanceStep, Workitem

• Not supported: Create or restore via API
• Result: Approval history is read-only and cannot be recreated or restored

Salesforce references:

• ProcessInstance Object
• ProcessInstanceStep Object

Customer options with our platform

Although Salesforce does not allow restoration of history objects, our platform provides these options:

• Export for audit – Customers can view and export history tables into CSV format for archival, audit, or external analysis.
• Custom history objects – Organizations may create custom history objects in Salesforce to capture and store change or approval data. These custom objects can be fully backed up and restored like any other Salesforce object.
