Restore from a previous full backup's tarfile

Browse Source 
Usage:  adb restore [tarfilename]

Restores app data [and installs the apps if necessary from the backup
file] captured in a previous invocation of 'adb backup'.  The user
must explicitly acknowledge the action on-device before it is allowed
to proceed; this prevents any "invisible" pushes of content from the
host to the device.

Known issues:

* The settings databases and wallpaper are saved/restored, but lots
  of other system state is not yet captured in the full backup.  This
  means that for practical purposes this is usable for 3rd party
  apps at present but not for full-system cloning/imaging.
