ndb_print_backup_file obtains diagnostic information from a cluster backup file.
file_name is the name of a cluster
backup file. This can be any of the files

Like ndb_print_schema_file and
ndb_print_sys_file (and unlike most of the
NDB utilities that are
intended to be run on a management server host or to connect to
a management server) ndb_print_backup_file
must be run on a cluster data node, since it accesses the data
node file system directly. Because it does not make use of the
management server, this utility can be used when the management
server is not running, and even when the cluster has been
completely shut down.
