# Backup & Recover for ServiceNow Limitations

When working with Backup & Recover for ServiceNow, take note of these points.

- Restoring is only supported to the same instance and not to a different instance.
- Restoring metadata to a ServiceNow environment is not supported.
- Specific tables sometimes fail to backup with Own Recover Connect due to the String Object Exceeded Max Size error: An internal server error (500) occurred for sys\_email on ServiceNow's side with text:{"error":{"message":"Script Evaluation Exception","detail":"String object would exceed maximum permitted size of 33554432"}
    
    The String Object Exceeded Max Size error occurs when the total record size for a row is more than 32 MB. This is related to a known ServiceNow platform limitation and the current workaround is to decrease the record size below 32MB. When encountered, Own falls back from Own Recover Connect to the Table API v2, and users may see records changed or removed within Smart Alerts or the Backup History. This is due to ACL checks between Own’s API and the Table API.
