Cause of the Problem

From Oracle documentation we get following information about the error ORA-00245.
ORA-00245 "control file backup failed; target is likely on a local file system"
// *Cause: Failed to create a control file backup because some process
// signaled an error during backup creation. This is likely caused
// by the backup target being on a local file system so it could not
// be accessed by other instances. It can also be caused by other
// I/O errors to the backup target. Any process of any instance that
// starts a read/write control file transaction must have access
// to the backup control file during backup creation.
// *Action: Check alert files of all instances for further information.

Solution of the Problem

1. Check the existing snapshot controlfile location:

rman> show all;

2. Configure the snapshot controlfile to a shared disk:

rman> CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'shared_disk/snapcf.f'; # default
