Expand description

The possible states of the Client’s room key backup mechanism.

A local backup instance can be created either by receiving a valid backup recovery key [1] or by having the Client create a new backup itself.

The Client can also delete and disable a currently active backup.

Backups will be enabled automatically if we receive the backup recovery key either from:

  • Another device using m.secret.send[2], which usually happens after completing interactive verification.
  • Secret storage[3], which is done by calling the SecretStore::import_secrets() method.

Variants§

§

Unknown

There is no locally active backup and we don’t know whether there backup exists on the server.

The reason we don’t know whether a server-side backup exists is that we don’t get notified by the server about the creation and deletion of backups. If we want to know the current state, we need to poll the server, which is done using the Backups::exists_on_server() method.

§

Creating

A new backup is being created by this Client. This state will be entered if you call the Backups::create() method.

§

Enabling

An existing backup is being enabled for use by this Client. We will enter this state if we have received a backup recovery key.

§

Resuming

An existing backup will be enabled to be used by this Client after the client has been restored. This state happens every time a Client is restored after we’d previously enabled a backup.

§

Enabled

The backup is enabled and room keys are actively being backed up.

§

Downloading

Room keys are currently being downloaded. This state will only happen after an Enabling state. The Client will attempt to download all room keys from the backup before transitioning into the Enabled state.

§

Disabling

The backup is being disabled and deleted from the server. This state will happen when you call the Backups::disable() method. After it has been disabled, we’re going to transition into the Unknown state.
