About this task
The Backup settings are defined at the card
level. Define the Backup setting for each input or output card as
required. Expand the Backup setting to define the
Switch, When, and
BackupLocation, which includes the directory and filename
values.
To define the Backup settings:
Procedure
-
From the Properties view of an input or output card, locate
the Backup setting and set the Switch
to ON. Use the When setting to define
under what circumstances a backup file is created. Select
Always or OnError.
-
Under the BackupLocation
Directory setting, specify if you want the backup data file
written to the Map directory or to a
Custom directory of your choice.
If you selected Custom, the
Value field appears under
Directory. If you selected Map, proceed to the next step.
-
In the Value field, browse your file structure and select a
directory for the backup file.
-
For the FileName setting, select
Custom to create a filename, or
Unique for a system-generated file name.
If you selected Custom, the
Action and Value fields
appear.
-
For the Action setting, specify how data should be written
to the backup file. Select Create to create a new file upon
map execution, which can overwrite an existing backup file with the same name, or
Append to append to an existing file, creating it if it
does not already exist.
-
In the Value field, enter a name for the custom file.
