Web DBM: SAP DB 7.4 
The Database Manager is the administration tool for SAP DB database instances. You can use this tool to create and monitor database instances on local or remote servers. You can back up the data in the database instances, and recover it, if necessary.
You can operate the Database Manager as a command line tool ( Database Manager CLI), as a graphical user interface (Database Manager GUI), or as a Web-based tool (Web DBM). All three types of this program offer the same range of functions.
You can install the Database Manager CLI and the Web DBM on all operating systems supported by the SAP DB database system. The Database Manager GUI can run on Microsoft Windows only.
Each
type of the Database Manager can administer SAP DB database instances on all
operating systems supported by the SAP DB database system (see
Operating System
Platforms).
You can use Version 7.4 of the Database Manager for all SAP DB database systems from Version 7.1.

Working with the Database Manager requires a thorough working knowledge of database administration.

You can download the Web DBM program free of charge from the SAP DB Homepage http://www.sapdb.org.
The
Web Tools Installation
Guide: SAP DB 7.4 and general information about the
SAP DB Database
System is on the SAP DB Homepage, under Documentation.
The
screen settings and procedures in the Web DBM largely resemble those in the
Database Manager GUI. For this reason, use the
Database Manager
GUI documentation when you work with the Web DBM. Always leave out the
first menu option when you specify paths for executing commands in the Web
DBM.

To activate or deactivate automatic log backups, choose the following:
In the Database Manager GUI, choose Instance ® Backup ® Autolog on/off
In the Web DBM, choose Backup ® Autolog on/off
