[. . . ] Backing Up and Restoring Software This chapter introduces the procedures you'll use to back up and restore the MCS software operating system, database, and applications software with the BackMaster utility. 9 Backing Up and Restoring Software Backing up the software on a bridge is a necessary and routine task that's often neglected. However, it's important to do it regularly and well to ensure that you can quickly recover from any type of bridge malfunction (a mechanical failure, for example) or a larger disaster (the facility burning down, for instance). If you do not have up-to-date backups, you cannot restore the bridge (or a replacement) to its current operating condition. Make every effort to keep a current backup copy of the entire system and the database: you never know when you'll need it. 2-1 BACKING UP AND RESTORING SOFTWARE Overview: What, When, and How You need to perform two types of backups in order to protect the different types of programs and data on the bridge and to minimize the amount of time you spend performing the task. u A full image backup creates a copy of everything on the MCS's hard drive: the operating system, the bridge's own software, and the data in the MCS database.

The MCS must be taken offline to back up the database, so make sure you do this at a time when no conferences are taking place. You need at least three formatted diskettes to perform this procedure. If your database is large, you may need more diskettes. To back up the database to diskette: 1. On the bridge, in the Workplace Shell, kill the MCS control program: a.
