Understand Data Loss Versus Data Corruption
Learning Objectives
After completing this unit, you’ll be able to:
- Apply Repair Data Corruption methods to fix corrupted field values.
- Apply Restore Data Loss methods to recover missing and related records.
- Restore metadata.
Our goal is to support your team's data integrity. Whether you're dealing with unexpected corruption or data loss, our restoration tools are designed to help get your source of truth back on track. Continue to follow along with Nina as she works to restore her data in different scenarios.
Repair Data Corruption
After a bad data import, Nina notices that specific record fields are corrupted across the organization. Instead of containing valid course codes like "MATH101" or "ENG201," the course code fields now show garbled text like "XYZ999" or random numbers. The record structure is intact, but the field values are wrong. In this situation, Nina decides to use the Repair Data Corruption tool.
Use Repair Data Corruption when you have:
- Field values that contain incorrect or garbled data
- Systematic corruption affecting specific fields across multiple records
- Data corrupted by faulty imports, integrations, or automation
- Situations where record structure is intact but field content is wrong
When Nina uses Repair Data Corruption for the course code issue:
- She identifies that only the course code field is affected.
- She selects a backup from before the faulty import occurred.
- The tool compares current field values with backup values.
- The system updates only records where the course code field differs from the backup.
- All other fields and related records remain untouched.
Restore Data Loss
In another scenario, Nina discovers records, their child objects, and the relationships between them were accidentally deleted during a cleanup process. An administrator deleted what they thought were test records, but they were actually active student enrollments with associated course registrations, grade records, and financial aid information.
Use Restore Data Loss when you have:
- Accidentally deleted records
- Missing relationships between parent and child records
- Records removed by faulty automation or user error
When Nina uses Restore Data Loss for the deleted enrollments, she selects a backup from before the accidental deletion. The tool identifies all the missing student enrollment records. It also identifies related course registrations, grades, and financial aid records. The restoration brings back all deleted records and rebuilds their relationships, and students can once again access their course information and grades.
The Backup & Recover restore function is a powerful tool for addressing different types of data issues. Precision Repair can be used for targeted restore efforts, Repair Data Corruption for damaged field values, and Restore Data Loss for missing records and relationships. Each approach has its place in your data recovery toolkit. With these tools and techniques, you're prepared to handle whatever data challenges come your way!
Restore Metadata
Data corruption and loss aren't the only challenges you might face. Sometimes the issue runs deeper and can affect the very structure and configuration of your Salesforce org. When custom fields, objects, workflows, or other metadata components are corrupted or accidentally deleted, you need to restore your org's metadata to get systems functioning properly again.
You might need to restore metadata in the following scenarios.
- Workflow rules or validation rules have been corrupted.
- Page layouts or record types have been damaged by failed deployments.
- Permission sets or profiles have been incorrectly modified.
Before you restore, a preview is generated, which shows you exactly which components are corrupted or missing. The preview is crucial because it shows you which metadata components will be restored and identifies potential deployment conflicts (for example, when a component is newer than the backup) and helps you spot missing dependencies required for a successful restoration. You can modify the restore job’s parameters and re-run the preview if needed, ensuring that you are comfortable with the restoration scope before proceeding.
Restore Full Organization: A Last Resort
In the extremely rare event that you face a situation where the damage is so extensive that targeted repairs aren’t sufficient, you might need to consider a full org restore.
A Full Org Restore reverts the entire Salesforce organization’s data to a previous point in time and should be considered a last resort. Before resorting to a full org restore, it’s important to understand the significant implications.
- Data loss risk: Any valid changes made after the selected restore point will be lost.
- Downtime requirements: Repair Full Organization typically requires scheduled downtime.
- Integration disruption: External integrations might need reconfiguration after a full org restore.
- User impact: All users will lose recent work and will need to recreate data entered after the restore point.
Sum It Up
Efficient data recovery relies on selecting the right tool for the job. You’ve learned how to use the Compare tool to investigate changes and define the scope of an issue before taking action. You know to use Precision Repair to focus on the critical configuration of date ranges, objects, and field filters to correct specific issues like corrupted field values without disrupting your entire organization. To use Repair Data Corruption to correct garbled field values and to use Restore Data Loss to recover deleted records and relationships. For structural issues you know to apply Restore Metadata. Regardless of the method, always follow best practices: Investigate first, prioritize targeted options, communicate with stakeholders, and document your recovery steps.
