Restore data

You can restore a backup of your configuration, time series data or alarming data. You can also use the restore function to copy the configuration to several other IEDs. The configuration file can be encrypted. If this is the case, the set password needs to be provided to perform the restore.

Restoring a data backup

When you restore a backup of your data, only the data that was included at the time of the last data backup is restored. Recent changes made in IIH Essentials since the last data backup are lost when the data backup is restored.

For this reason, we recommend making regular backups of the data.

Prerequisites

Existing files:

• Configuration data: iih-essentials-backup-config.json
• Time series data: iih-essentials-backup-data.txt
• Alarm data: iih-essentials-backup-alarm-data.txt

Procedure

To upload or restore the configuration data, follow these steps:

1. In the navigation bar, click "Settings".
2. Expand the "Backup and restore" section.
3. Under "Data recovery", click "Upload file".
   The selection window in the Explorer opens.
4. Select the file (.json) required for the configuration.
5. Click "Open".
   The file name is displayed.
   1. If the configuration is encrypted, provide the password.
6. (Optional) Select a time series file to restore.
7. (Optional) Select an alarming file to restore.

8. To upload the configuration file(s), click "Upload".
   

   Data is overwritten

   When you confirm the dialog, the previous data is overwritten.

9. Click "Confirm"

It is possible to restore the time series and alarming data independent of a configuration file.

Missing parts of the configuration

The restore process will fail, if parts of the needed configuration are missing.
