State locking prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss1.

The default “local” Terraform backend stores the state file in a local file named terraform.tfstate, which can be used to track and manage the state of your infrastructure3.

This command will initialize the new backend and prompt you to migrate the existing state file to the new location4. The other commands are not relevant for this task.
