docs/command/atlas-backups-restores-start.txt

@@ -17,7 +17,8 @@ Start a restore job for your project and cluster.
 If you create an automated or pointInTime restore job, Atlas removes all existing data on the target cluster prior to the restore.
 
 To use this command, you must authenticate with a user account or an API key with the Project Owner role.
-Atlas supports this command only for M10+ clusters.
+Atlas supports this command only for Flex and M10+ clusters.
+Flex clusters support only automated restore jobs.
