A Quick Look at MySQL 6.0’s New Backup
I still remember the day. I was working for a large systems integrator on a very major account, and had responsibility for some DB2 databases, but also had the unfortunate duty of also taking care of some legacy IMS databases (hierarchical IBM databases used quite a lot ‘back in the day'), which I knew next to nothing about. One morning I was asked to make a small change to a very large and prominent IMS database - just remove one record - what could go wrong? The guy who knew IMS real well was gone so I put together a program to do the job (yes, you actually had to write a program to do it), and ran it after hours. I came in the next day and tried to access some records in the database. Nothing. All gone, except for - ta-da - the one record I wanted to remove! At the instant I realized my mistake, I was acutely aware of two things: (1) I was in serious trouble if I didn't have a backup, and (2) I was in desperate need of a complete change in underwear.

ndb_print_backup_file

NDB_PRINT_BACKUP_(1)					       MySQL Database System					      NDB_PRINT_BACKUP_(1)

NAME

       ndb_print_backup_file - print NDB backup file contents

SYNOPSIS

       ndb_print_backup_file file_name

DESCRIPTION

       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 17.5.3.1, "MySQL 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.
	       Additional Options

       None.
