-In case autorestic throws the error message `an instance is already running. exiting`, but there is no instance running you can unlock the lock.

-To verify that there is no instance running you can use `ps aux | grep autorestic`.

-Example with no instance running:
-
-```bash
-> ps aux | grep autorestic

 The following hooks groups are supported, none are required:

-The difference between `prevalidate` and `before` hooks are that `prevalidate` is run before checking the backup location is valid, including checking that the `from` directories exist. This can be useful, for example, to mount the source filesystem that contains the directories listed in `from`.
