21.5.18 ndb_print_backup_file — Print NDB Backup File Contents

ndb_print_backup_file obtains diagnostic information from a cluster backup file.

Usage

ndb_print_backup_file file_name

filename 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 subdirectoryBACKUP-_`#`_, where_#_ is the sequence number for the backup. For more information about cluster backup files and their contents, seeSection 21.6.8.1, “NDB Cluster Backup Concepts”.

Like ndb_print_schema_file andndb_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.

Additional Options

None.
