-    rclone backend restore s3:bucket/path/to/directory -o priority=PRIORITY -o lifetime=DAYS
-    rclone backend restore s3:bucket -o priority=PRIORITY -o lifetime=DAYS

+    rclone backend restore s3:bucket/path/to/directory [-o priority=PRIORITY] [-o lifetime=DAYS]
+    rclone backend restore s3:bucket [-o priority=PRIORITY] [-o lifetime=DAYS]

 This flag also obeys the filters. Test first with --interactive/-i or --dry-run flags

-    rclone --interactive backend restore --include "*.txt" s3:bucket/path -o priority=Standard -o lifetime=1
+    rclone --interactive backend restore --include "*.txt" s3:bucket/path -o priority=Standard

 All the objects shown will be marked for restore, then

-    rclone backend restore --include "*.txt" s3:bucket/path -o priority=Standard -o lifetime=1
+    rclone backend restore --include "*.txt" s3:bucket/path -o priority=Standard
