Backup

The Backup action initiates a full backup that includes all online database files or a partial backup that excludes frozen files or frozen partitions, or both frozen files and partitions. Offline files and partitions are always excluded.

You can execute this command in multiuser mode to perform an online backup, with concurrent updating transactions or in quiesced (read-only) mode. In single user mode, the path argument is required.

The syntax of the Backup action is as follows.

jdbadmin action=Backup
         backupDir=backup-directory
         [path=database-path]
         [ini=initialization-file-name]
         [server=multiUser|singleUser]
         [compress=true|false]
         [excludeFrozenFiles=true|false]
         [excludeFrozenPartitions=true|false]
         [overwrite=true|false]
         [quiesced=true|false]
         [showProgress=true|false]
         [verify=true|false]

In addition to the command line argument values that apply to one or more batch database administration utility actions or commands, documented under "Command Arguments", the Backup action arguments are listed in the following table.
