This storage keeps information about deleted objects. You can also restore them.
You cannot create and edit records in the Record Deletion Log(sys_record_deletion_log) table. Only users with the admin role can read and delete them.
To access this storage, navigate to System Logs → Record Deletion Log.
Deletion logs are only available to tables with the selected Record Deletion Logging checkbox. See the Table Attributes article to learn more.
If you need to find specific records or to sort them in a particular order, use a filter tool at the top of the page. Use the Condition Builder to configure the filters that will fit your needs most.
ID of the deleted record that caused deletion of the current record: if the record A causes deletion of record B, and this causes deletion of record C, then for the C record this field will display record A ID (as the initial cause).

The restored record will have the attributes described in the JSON field. The system restores record version as it was just before the deletion.
Records are restored one by one, independently from each other. For example, if deletion of record A causes deletion of records B and C, and then record A is restored, records B and C will remain deleted. They need to be restored additionally.
