    Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the set of related devices. The method stores the backup data encrypted with a set of data encryption keys. The method also stores the set of data encryption keys encrypted with a master recovery key. The method also stores several copies of master recovery key data, each copy of the master recovery key data encrypted with a public key of a different one of the related devices. The backup data is only recoverable by accessing a private key of any one of the related devices.

    Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the devices. The method receives a command to create a backup for a subset of data synchronized between a subset of the devices, which is a subset of all data synchronized between the devices. The method identifies the subset of synchronization data from the set of all synchronization data. The subset of synchronization data is tagged as pertaining to a particular set of criteria for synchronization between only the subset of devices. The method stores a backup of the subset of synchronization data in a backup storage encrypted in such a way that requires a recovery key associated with any one of the devices in the subset of devices to access the backup while preventing access to the backup with recovery keys of any of the other devices.

    Abstract translation: 一些实施例为一组相关设备中的特定设备提供用于备份在设备之间同步的数据的方法。 该方法接收命令以创建在设备子集之间同步的数据子集的备份,这是设备之间同步的所有数据的子集。 该方法从所有同步数据的集合中识别同步数据的子集。 同步数据的子集被标记为仅在设备子集之间进行同步的特定标准集合。 所述方法将备份所述同步数据的子集存储在备份存储器中,所述备份存储器以需要与所述设备子集中的所述设备中的任一个相关联的恢复密钥加密的方式来访问所述备份,同时防止使用恢复密钥访问所述备份 的任何其他设备。
