backup_history_list

Use

You display the content of the backup history. You can restrict or extend the display by specifying options.

To save time, we recommend that you execute the DBM command for getting the backup history (see: backup_history_open) first. If you do not execute this command first, it is executed implicitly with the DBM command for displaying the backup history described here.

The line has an E:-prefix and is followed by the columns, each separated by a vertical line (|).
