+
+<p><code>bmgr</code> is a shell tool that developers can use to interact with the Backup Manager
+on Android devices supporting API version 8 or later.  It provides commands for inducing backup
+and restore operations on demand so that you do not need to repeatedly wipe data or take similar
+intrusive steps to test the operation of an application's backup agent.  These commands are
+accessed via the <a href="{@docRoot}guide/developing/tools/adb.html">adb</a> shell.
+
+<p>There are a couple of basic concepts used by the Backup Manager that are built into the way
+that <code>bmgr</code> operates.  These are <a href="#transports">backup transports</a> and
+<a href="#restoresets">restore sets</a>.
+
+
+<a name="transports"></a>
+<h2>About backup transports</h2>
+
+<p>A <em>backup transport</em> is the code module responsible for moving backup and restore data
+to and from some storage location.  A device can have multipe transports installed, though only
+one is active at any given time.  Transports are identified by name.  You can see what
+transports are available on your device or emulator by running the
+<code>bmgr list transports</code> command:
+
+    <pre>adb shell bmgr list transports</pre>
+
+<p>The output of this command is a list of the transports available on the device.  The currently
+active transport is flagged with a <code>*</code> character.  Transport names may look like
+component names -- for example, <code>android/com.android.internal.backup.LocalTransport</code> --
+but they need not be, and the strings are never used as direct class references.  The use of
+a component-like naming scheme is simply for purposes of preventing name collisions.
+
+<p>You can change which transport is currently active from the command line as well:
+
+    <pre>adb shell bmgr transport NAME</pre>
+
+<p>where <code>NAME</code> is one of the names as printed by the <code>bmgr list transports</code>
+command.  From this point forward, backup and restore operations will be directed through the
+newly-selected transport.  Backup state tracking is managed separately for each transport, so
+switching back and forth between them will not corrupt the saved state.
+
+
+<a name="restoresets"></a>
+<h2>About restore sets</h2>
+
+<p>All of the application data that a device has written to a given backup transport is tracked
+together, and is collectively sometimes called a <em>restore set,</em> because the typical use
+of the data set is during restore operations.  Each time a device is initially provisioned, a
+new data set is established.  The user can get a listing of all the data sets that can be
+restored through the current transport by running this shell command:
+
+    <pre>adb shell bmgr list sets</pre>
+
+<p>The output is listing of available restore sets, one per line.  The first item on each line is
+a <em>token,</em> a number in hexadecimal that identifies the restore set to the transport.  After
+that is a string that may provide some brief identifying information about the restore set.  Only
+the token is actually used within the backup and restore mechanism.
+
+
+<a name="backup"></a>
+<h2>Forcing a backup operation</h2>
+
+<p>Normally, applications notify the backup manager directly that their data has changed, in
+response to which the backup manager will make sure to invoke that application's agent when the
+next backup operation is run.  You can simulate this manually from the command line if you wish,
+by running this shell command:
+
+    <pre>adb shell bmgr backup PACKAGE</pre>
+
+<p><code>PACKAGE</code> is the formal package name of the application you wish to schedule for
+backup.  At this point you know that the application's agent will be invoked for backup at some
+point in the future, though there is no hard guarantee of when that will occur.  You can force
+all pending backup operations to run immediately by using the following command:
+
+    <pre>adb shell bmgr run</pre>
+
+<p>This causes a backup pass to execute immediately, invoking the agents of all applications that
+had called <code>BackupManager.dataChanged()</code> since the time of the last backup operation,
+plus any applications which had been manually scheduled for backup via
+<code>bmgr backup PACKAGE</code>.
+
+
+<a name="restore"></a>
+<h2>Forcing a restore operation</h2>
+
+<p>Unlike backup operations, which are batched together and run on an occasional basis, restore
+operations execute immediately.  The backup manager currently provides two kinds of restore
+operations.  The first restores an entire device with the data from a given restore set.  This
+is typically only performed when a device is first provisioned, to replicate settings and other
+such saved state from the user's previous device.  The second kind of restore operation restores
+a single application from the <em>active</em> data set; that is, from the data set currently
+being written to by backup operations.  This second form is available as part of the public API.
+It allows applications to abandon their current data and revert to the last-known-good data as
+represented in their current backup image.
+
+<p>A full-system restore operation can be initiated with this shell command:
+
+    <pre>adb shell bmgr restore TOKEN</pre>
+
+<p>where <code>TOKEN</code> is the desired restore set's token as printed out by the <code>bmgr
+list sets</code> command.  <strong>Warning!</strong>  This operation will <em>replace</em> the
+data of all backup-enabled applications with the contents of the given restore set.  Be careful,
+and be aware of the potential consequences.
+
+<p>A single-application restore operation does not reference a restore set token; it always uses
+the data from the currently active data set.  You can induce such an operation from the command
+line like this:
+
+    <pre>adb shell bmgr restore PACKAGE</pre>
+
+<p><code>PACKAGE</code> is the formal package name of an application that is participating in the
+backup/restore mechanism.  The backup manager will immediately instantiate the application's
+agent and invoke it for restore.
+
+<a name="other"></a>
+<h2>Other commands</h2>
+
+<p>The data for a single application can be erased from the active data set on demand.  This is
+very useful during development of backup agents, in case bugs lead you to write corrupt data
+or saved state information.  The shell command for wiping an application's data is this:
+
+    <pre>adb shell bmgr wipe PACKAGE</pre>
+
+<p><code>PACKAGE</code> is the formal package name of the application whose data you wish to
+erase.  The next backup operation that the application's agent processes will look as
+though the application had never backed anything up before.
+
+<p>You can see whether the backup manager is operational at all by running this command:
+
+    <pre>adb shell bmgr enabled</pre>
+
+<p>This might be useful if your application's agent is never being invoked for backup, to verify
+whether the operating system thinks it should be performing such operations at all.  You can also
+directly disable or enable the backup manager with this command:
+
+    <pre>adb shell bmgr enable BOOLEAN</pre>
+
+<p>where <code>BOOLEAN</code> is either <code>true</code> or <code>false</code>.  This is
+equivalent to disabling or enabling backup in the device's main Settings UI.
+<strong>Warning!</strong>  When backup is disabled, the current transport will explicitly wipe
+the entire active data set from its backend storage.  This is so that when a user says that no,
+they do not want their data backed up, the backup manager respects that wish.  No further data
+will be saved from the device, and no restore operations will be possible, unless the backup
+manager is re-enabled (either through Settings or through the above <code>bmgr</code> command).
