+Backup and Restore Not Supported During Resharding Operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently, a resharding operation may pin timestamps in the storage
+engine in a manner that prevents a restore operation from proceeding.
+Once :issue:`SERVER-58392` is resolved, you will be able to backup and
+restore your collection while a resharding operation occurs.
+:issue:`SERVER-58392` is expected to be resolved in a patch release of
+MongoDB 5.0.
