Tab: Backup and Restore

On this tab of the generic device editor, you initiate the backup and restore of the application-specific files on the PLC. To do this, you place a packed backup file or read one back in.

For more information, see: ⮫ “Backup and Restore ”

Requirement: The communication settings for the connection to the device are correct. The application for which you want to perform a backup exists on the controller.

Table 583: Menu bar
“Backup”	The button opens a menu with the following commands: “Read Backup Information from Device”: The command searches for application-specific files from the `‎$PlcLogic$‎` directory of the PLC and displays them as a table at the bottom of the tab. “Create Backup File and Save to Disk”: Requirement: The “Read Backup Information from Device” command was used for determining the backup-relevant files. These files are located in the table in the lower part of the tabbed page. The command compresses the files in the table set as “Active” and the `‎meta.info‎` information file into a backup zip file. The file extension is `‎tbf‎` (="Target Backup File"). “Save Backup File to Device”: Requirement: The backup file has been saved to the disk. The command saves the backup file to the `‎TBF‎` directory of the PLC.
“Restore”	The button opens a menu with the following commands: “Load Backup File from Disk”: The command opens the “Open” dialog for navigating the file system for a saved backup file. The included files are listed in a table in the lower part of the tabbed page. “Load Backup File from Device”: The command generates a list of all backup files found on the PLC. Select one of these files to view its contents in a table on the tabbed page. For the restore operation, you can deactivate optional components and edit the comments. “Restore Backup to Device”: The command is available if at least one component of the backup file that is currently loaded on the tab is set to active. It prompts for restoring the application status on the device. The user interface is blocked during restore. You can cancel the operation.
