Backup and restore
During a backup, a backup file is created that contains the configuration and other data for the phone. If required, this backup file can be uploaded to the phone again.
A data backup can, for example, be useful if the phone is reset to its factory settings and it is not planned to completely reconfigure it.
*Note: Uploading the backup file can involve a data migration. The phone cannot be used while this is happening. A message appears on the display to tell you a data migration is taking place.

A data backup involves protected data. Before downloading starts, you must acknowledge that in the dialog window.
*Important: Comply with the legal notes below before backing up the data. The data backup includes these elements with special legal protection:

All the phone's users must be informed that this content will be transferred, and who will process the data obtained, before a backup is created.
