Element	Description
List of most recently opened files	From the drop down list, select the appropriate number of entries to be stored with the MRU list on the File menu.

4. In the navigator, select Files & protocols > Backup copy.

5. Select the desired options.

Element	Description
Automatic backup every ... minutes	Use this option to define, whether Visum shall save a backup copy of the current network version at regular intervals. The backup copy has the name of the currently loaded file and also its file extension. Additionally, the file extension .ves is added automatically (Example: example.net.ves). By default, the backup copy is saved to the directory in which the currently loaded file has been stored. This you can change via option Common folder for backup copy. Enter the time gap between two backup copies (maximum: 120 minutes). Notes To open a backup copy, rename it to *.ver and read it from file like a version file. Visum cannot save a backup copy as long as a modal window is open. In this case, the backup copy will be created as soon as the window is closed. This guarantees that only consistent data states are saved to file. If no file is currently opened, for example directly after program start, the backup copy is saved to the standard folder for version files (Changes to settings in the configuration file) under the name Tmpn.ves.
Common folder for backup copy	Use this option to define a common directory that stores all backup copy files (cf. option Automatic backup every ... Minutes). As long as no folder has been selected here each backup copy is saved to the directory from which the currently open file has been read. Notes Existing files with the same name in this directory will be overwritten. If no backup copy can be created, for example due to insufficient access rights to the target folder, Visum will first try to save the backup copy to the standard directory for version files under the name Tmpn.ves (Changes to settings in the configuration file). If this also fails, a message will appear.

Common folder for backup copy

Use this option to define a common directory that stores all backup copy files (cf. option Automatic backup every ... Minutes). As long as no folder has been selected here each backup copy is saved to the directory from which the currently open file has been read.

Notes

Existing files with the same name in this directory will be overwritten.

If no backup copy can be created, for example due to insufficient access rights to the target folder, Visum will first try to save the backup copy to the standard directory for version files under the name Tmpn.ves (Changes to settings in the configuration file).
