If you have a recent version of Enterprise Expedition flow, then you have likely encountered the iCDB Project Backup tool. In this Tip of the Week, I’ll explain the different types of backups the tool supports.

 

AutoSave

These are periodic backups done at a fixed interval, which may be configured by the user. Note that this backup will only occur if the design has changed. You may also configure how many backups you want to keep. Older copies get marked for purge. See also Application below.

 

SessionStartup

This backup gets created when a project (design) is opened. The number of backup copies is user configurable.

 

SessionShutdown

This backup is created when a project is (design) is closed. The number of backup copies is user configurable.

 

Application

This is legacy functionality that has been replaced by AutoSave (above). Interval and number of backups is user configurable. You do not need both Application and AutoSave enabled.

 

DxD Diagnostic

This is a system backup that is automatically created before repairing the design with DxDesigner Diagnostics. It is not user configurable by default.

 

CES Diagnostic

This is a system backup that is automatically created before repairing the design with CES Diagnostics. It is not user configurable by default.

 

Database Upgrade

This backup is automatically created before the design is upgraded to new software version. It is not user configurable by default.

 

User

These refer to backups that are manually launched by the user from iCDB Project Backup utility. The user may configure how many of these backups to keep before they are marked for purge.

 

There are a few other backup types, but these are the most common ones. You can see them all from the iCDB Project Backup tool when you select Backup > Settings from the pull down menu in the iCDB Project Backup utility.

 

Note that many of the backup types appear greyed out in the settings dialog. By design, only the user level backups are configurable. You can change this behavior by modifying the iCDB Project Backup tools configuration file.

 

More information about this tool is available in the Concurrent Design Administrator’s Guide.

 

That’s it for this week!
