Reverse Synchronization is subject to heavy load and must recover from sudden system outages. The following features prevent data loss and enhance performance:
When Reverse Synchronization runs, all the names of accounts modified in the target system are stored in the IDF_Reverse_Recovery table. If the system fails, the next Reverse Synchronization run continues the processing for all the accounts still left in the table.
Some attributes are likely to change every day, such as Windows Last Login. As a result, the Reverse Synchronization is heavily loaded with new data. However, you may want to track such attributes for reporting purposes. So, you can declare these attributes in the IDF_Reverse_Additional_Attr table. These attributes will be optimized, and will not slow down the Reverse Synchronization, but the new data will be taken from the target system.
