ndb_print_backup_file obtains diagnostic information from a cluster backup file.
Usage
ndb_print_backup_file file_name
file_name is the name of a cluster
backup file. This can be any of the files
(.Data, .ctl, or
.log file) found in a cluster backup
directory. These files are found in the data node's backup
directory under the subdirectory
BACKUP-, where
## is the sequence number for the
backup. For more information about cluster backup files and
their contents, see
Section 22.5.3.1, “NDB Cluster Backup Concepts”.
Like ndb_print_schema_file and
ndb_print_sys_file (and unlike most of the
other 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.
In NDB 8.0.17 and later, this program can also be used to read undo log files.
Additional Options
None.
