WebDAV synchronization

Back up your data automatically to your own WebDAV server.

Overview

You connect Bunt to your WebDAV server. Bunt uploads your backups there and restores them on your other devices.

How to find it

  1. Open the side menu and select Settings.
  2. Tap Backup.
  3. In the WebDAV section, tap Configure WebDAV.

Step by step

  1. Enter the Server address and Target folder.
  2. Enter your Username and Password.
  1. Tap Test connection.
  2. Confirm your server's certificate if prompted.
  3. Tap Save.

Optional

  • Show backups: Open the list of server backups in the WebDAV section.
  • Restore: Load a server backup onto this device.
  • Delete older backups: Limit the number of server backups per device.
  • Disconnect: Remove credentials and settings from this device.

MDM configuration

School administrators can pre-fill or block WebDAV via MDM. Fields that are set are fixed in the app and can no longer be changed by the user. Example configuration (without iCloud):
