/**

 * A proxy to BackupManagerService implementation.

 *

 * This is an external interface to the BackupManagerService which is being accessed via published

 * binder (see BackupManagerService$Lifecycle). This lets us turn down the heavy implementation

 * object on the fly without disturbing binders that have been cached somewhere in the system.

 *

 * This is where it is decided whether backup subsystem is available. It can be disabled with the

 * following two methods:

 *

 * <ul>

 * <li> Temporarily - create a file named Trampoline.BACKUP_SUPPRESS_FILENAME, or

 * <li> Product level - set Trampoline.BACKUP_DISABLE_PROPERTY system property to true.

 * </ul>
