Description

一种终端恢复出厂设置时的数据恢复方法及终端 技术领域
本申请涉及终端领域，尤其涉及一种终端恢复出厂设置时的数据恢复方法及终端。
背景技术
手机等终端一般都设有恢复出厂设置(recovery，也可称为一键还原或重置手机)的功能。该功能具体是指将手机恢复到手机出厂售卖时的状态，恢复出厂设置后手机现有的所有设置，存储和安装的应用以及应用中的数据都将被清空，回到出厂时的原始设定状态。
一般，为了不丢失手机内的照片、音乐、应用等数据，用户可在恢复出厂设置前将这些数据先备份在电脑、手机的SD卡(secure digital card)或者云端服务器等外部存储设备中。当手机完成恢复出厂设置的操作后，用户可以再将已经备份的数据恢复至手机内。可以看出，整个恢复出厂设置的操作过程较为繁琐，且备份和恢复数据的过程均需依赖Wi-Fi网络环境或外部存储设备等外部资源，使得整个恢复出厂设置过程中数据的稳定性和安全性随之降低。
发明内容

活动管理器：用于管理每个应用的生命周期。应用通常以Activity的形式运行在操作系统中。对于每一个Activity，在活动管理器中都会有一个与之对应的应用记录(ActivityRecord)，这个ActivityRecord记录了该应用的Activity的状态。活动管理器可以利用这个ActivityRecord作为标识，调度应用的Activity进程。
窗口管理器：用于管理在屏幕上使用的图形用户界面(graphical user interface，GUI)资源，具体可用于：获取显示屏大小、窗口的创建和销毁、窗口的显示与隐藏、窗口的布局、焦点的管理以及输入法和壁纸管理等。
内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。

应用程序层中的各个应用在运行时产生的应用数据可被保存至ROM中相应的目录或文件夹内。并且，应用程序层中可安装用于管理终端内应用及文件的手机管家APP。手机管家APP中一般设置有“一键还原”或者“重置手机”等用于恢复终端出厂设置的功能。
其中，终端的恢复出厂设置功能实际是android定义的一个标准刷机协议。当用户打开恢复出厂设置功能后，终端可启动并进入恢复(recovery)模式。在recovery模式下，终端可执行ROM内recovery分区中的相关程序，例如recovery程序。通过recovery程序，终端可以完成清除数据、安装刷机包等操作。
在本申请实施例中，如果终端检测到用户从手机管家APP中打开“一键还原”或者“重置手机”的功能，终端可提示用户选择希望备份的待恢复数据，例如，照片、视频、通讯 录以及应用等。用户选中的这些待恢复数据实际存储在ROM的data分区内，为防止终端恢复出厂设置时对data分区格式化而造成数据丢失，终端可将这些待恢复数据先备份到除data分区之外的存储空间(本申请中可称为目标存储空间)中。例如，可以将上述待恢复数据备份至终端的RAM内，或者，将上述待恢复数据备份至ROM的其他分区内。进而，终端可进入上述recovery模式，通过执行相应的recovery程序将data分区内的数据格式化，使得终端恢复为出厂时的状态。
当终端将data分区内的数据格式化之后，可提示用户将已经备份的待恢复数据重新恢复至data分区，使得手机在恢复出厂设置的同时能够保留用户不希望被清除的应用等数据。另外，上述待恢复数据的备份和恢复过程都是借助终端内的存储资源完成的，因此在整个恢复出厂设置的过程中，终端可以在不借助外部存储设备的同时，保证待恢复数据的安全性和稳定性。
另外，当终端将已经备份的待恢复数据重新恢复至data分区后，终端可将目标存储空间内的待恢复数据删除，避免待恢复数据占用终端后续正常使用时的存储资源。
为了便于理解，以下结合附图对本申请实施例提供的一种终端恢复出厂设置时的数据恢复方法进行具体介绍。以下实施例中均以手机作为终端举例说明。
图4为本申请实施例提供的一种终端恢复出厂设置时的数据恢复方法的流程示意图。如图4所示，该数据恢复方法可以包括：
S401、手机接收用户打开恢复出厂设置功能的第一输入。
如果用户希望将手机恢复到出厂售卖时的状态，用户可进入手机的设置界面或打开手机管家APP，查找恢复出厂设置这一功能选项。如图5所示，设置界面501中设置有用于恢复出厂设置的选项502。当手机检测到用户打开选项502时，说明用户执行了打开恢复出厂设置功能的第一输入，此时手机可继续执行下述步骤S402-S408完成手机恢复出厂设置、以及恢复出厂设置前后的数据备份和恢复操作。
S402、响应于上述第一输入，手机显示包含至少一项候选数据的显示界面。
其中，上述各项候选数据一般均存储在手机的ROM内。例如，存储在ROM的data分区内。示例性的，用户使用视频应用1下载的视频一般存储在data分区内与视频应用1对应的文件夹中，用户使用视频应用2下载的视频一般存储在data分区内与视频应用2对应的文件夹中。而当手机恢复出厂设置时会将data分区内的所有数据格式化，造成用户数据丢失。
因此，在手机接收到上述第一输入后，如图6所示，手机可跳转至包含待备份的候选数据的显示界面601。用户可以在显示界面601中选择恢复出厂设置时用户希望保留的待恢复数据。例如，上述显示界面601中包括联系人、短信、照片、通话记录、音乐以及应用等至少一项候选数据。其中，某一应用作为候选数据时具体可以包括其应用程序本身，还可以包括用户在使用该应用过程中产生的记录数据和储存的文件，例如联系人头像、缓冲和下载好的图片等。另外，仍如图6所示，手机还可以在显示界面601中显示每一项候选数据所占用的存储空间的大小。
当然，用户在上述显示界面601中选中某一项候选数据后，手机还可以进一步跳转至该项候选数据的详情界面中。例如，用户选中显示界面601中的应用后，手机可显示当前手机内安装的所有应用(例如15个应用)，这样用户可以在这些应用中选择具体将哪些应 用进行备份，以避免手机恢复出厂设置后相应的应用丢失。
另外，在手机接收到上述第一输入后，手机还可以查询ROM的data分区内是否存储有上述候选数据。如果没有存储上述候选数据，则手机恢复出厂设置后不会造成数据丢失的情况，因此，手机可按照现有的恢复出厂设置的流程对ROM中的数据进行格式化。相应的，如果存储有上述候选数据，则手机可按照步骤S402所述的方法显示包含至少一项候选数据的显示界面。
S403、手机接收用户在上述显示界面中选中待恢复数据的第二输入。
其中，用户在上述显示界面中选中的一项或多项候选数据即为手机恢复出厂设置前后需要备份和恢复的待恢复数据。
仍以图6所示的显示界面601举例，在步骤S403中，如果检测到用户点击显示界面601中的联系人、信息以及通话记录这三项候选数据，且检测到用户点击确认按钮602，则说明用户执行了上述第二输入，此时手机可将ROM中存储的联系人、信息以及通话记录确定为待备份的待恢复数据。当然，上述第二输入也可以为拖动操作、长按操作或按压操作等，本申请实施例对此不做任何限制。
S404、响应于上述第二输入，手机对上述待恢复数据进行标记。
在手机接收到上述第二输入后，手机可对用户选中的待恢复数据进行标记，以便手机后续恢复出厂设置时能够区分出哪些是用户希望保留的数据。
示例性的，手机可创建一份备份清单，并在该备份清单中记录上述待恢复数据的具体存储路径。例如，用户选中的待恢复数据中包括应用A和应用B，那么，手机可将应用A在ROM中的存储路径“data/app/taobao.com”记录在备份清单中，并将应用B在ROM中的存储路径“data/app/weixin.com”记录在备份清单中。这样，手机通过读取备份清单可以获知哪些数据是被用户选中的需要备份的待恢复数据。
又或者，手机可以对用户选中的待恢复数据添加相应的标识。例如，可以在上述待恢复数据所在的文件中添加一个头文件，或者，可以在上述待恢复数据所在的文件夹中添加一个标识文件。这样，手机通过读取上述头文件或标识文件可以获知哪些数据是被用户选中的需要备份的待恢复数据。
S405、手机将已标记的待恢复数据备份至目标存储空间。
其中，目标存储空间可以是手机内除ROM中data分区之外的任意存储空间。例如，目标存储空间可以是手机中的RAM，或者，手机也可动态地创建一个新分区作为目标存储空间。当手机执行恢复出厂设置的操作时，不会对目标存储空间内的数据进行格式化。
以安卓操作系统为例，手机的运行模式一般包括正常模式(normal mode)、安全模式(safe mode)、引导模式(bootloader mode)以及恢复模式(recovery mode)等。当手机对上述待恢复数据进行标记之后，手机可自动进入recovery模式，也可在用户手动确认对手机执行恢复出厂设置这一操作后进入recovery模式。例如，当手机对上述待恢复数据进行标记之后，如图7所示，手机可弹出对话框701提示用户确认是否执行恢复出厂设置的操作，如果用户输入确认执行恢复出厂设置的操作，则手机可自动关机，再自动开机后进入recovery模式。
当手机进入recovery模式后，手机可先查看手机内是否存储有被标记的待恢复数据。例如，手机可读取步骤S404中创建的备份清单，如果备份清单中记录有被标记的待恢复 数据，则说明在对手机恢复出厂设置之前需要先备份该待恢复数据，避免恢复出厂设置之后该待恢复数据丢失。否则，手机可直接执行恢复出厂设置的操作。
另外，手机在上述步骤S404中对待恢复数据进行标记时，手机还可计算备份上述待恢复数据所需的空间大小。以目标存储空间为手机的RAM举例，如果上述待恢复数据所需的空间大小小于或等于RAM中可用存储空间的大小，则如图8所示，手机进入recovery模式后可跳转至界面801，在界面801中提示用户正在对用户选中的待恢复数据进行备份。同时，手机可按照备份清单中记录的存储路径读取到用户选中的待恢复数据，进而将该待恢复数据拷贝至RAM中完成备份。
如果手机计算出上述待恢复数据所需的空间大小小于RAM中可用存储空间的大小，则手机可先执行内存清理操作以释放出尽量多的RAM空间。如果在执行内存清理操作后，RAM中可用存储空间大小仍无法满足待恢复数据所需的空间大小，则手机可继续停留在上述显示界面601中，此时，如图9所示，手机可在显示界面601中显示提示语901，以提示用户当前的可用的备份空间不足，需要用户取消部分选中的待恢复数据。用户可根据提示语901在显示界面601中取消在步骤S403中选中的一项或多项待备份的待恢复数据，直至RAM的可用存储空间大小能够满足用户更新后的待恢复数据所需的空间大小。进而，如图8所示，当手机进入recovery模式后，可按照备份清单中记录的存储路径读取到用户最终更新后的待恢复数据，并将该待恢复数据拷贝至RAM中完成备份。
示例性的，手机可将ROM中data分区内的待恢复数据拷贝至RAM的tmp分区。tmp分区一般用来存放手机运行时产生的临时文件，将待恢复数据拷贝至tmp分区可避免手机备份该待恢复数据时占用额外的系统资源，增加手机在recovery模式下的负载。
在本申请的另一些实施例中，当手机进入recovery模式后，如果手机通过读取备份清单确定需要对用户选中的待恢复数据进行备份，则手机可根据上述待恢复数据所需的空间大小，在ROM的空闲存储空间内创建一个新的分区，例如resume分区，此时，这个新创建的resume分区即为目标存储空间。
例如，手机的ROM大小为128G，除data分区之外未被占用的存储空间还剩余80G，而上述待恢复数据所需的空间大小为20G。那么，手机可在剩余的80G存储空间中开辟一个大小为20G的resume分区。进而，手机可按照备份清单中记录的存储路径读取到上述待恢复数据，并将该待恢复数据拷贝至新创建的resume分区中完成备份。
或者，由于data分区的存储空间一般比较大，因此，手机也可以从data分区中开辟一个新的分区作为目标存储空间。例如，ROM中data分区的大小为90G，其中有30G未被占用的存储空间。用户选中的待恢复数据的大小为15G，那么，手机可以在上述30G未被占用的存储空间中创建一个15G的resume分区，用于存储上述待恢复数据。此时，新分区被创建后data分区的大小从90G变为75G。又例如，如果用户选中的15G待恢复数据的大小大于data分区中剩余的存储空间的大小，则手机可将data分区中除上述待恢复数据之外的数据删除，从而释放data分区内的存储资源。进而，手机可在data分区中创建一个大小满足上述待恢复数据大小的resume分区用于存储上述待恢复数据。
当然，手机也可以从ROM中的data分区内获取一部分存储资源，并且从除data分区之外的其他分区(例如系统分区)获取一部分存储资源(例如5G未被占用的存储空间)，进而使用这两部分存储资源创建新的resume分区。
又或者，目标存储空间可以既包括手机内的RAM，还包括上述新创建的resume分区。这样，手机可以将上述待恢复数据中的一部分备份至RAM中，并将上述待恢复数据中的另一部分备份至上述新创建的resume分区中。这样用户可以利用该目标存储空间备份尽可能多的待恢复数据。
另外，手机在上述目标存储空间内拷贝待恢复数据时，还可以先对待恢复数据进行压缩，尽可能减小待恢复数据占用的目标存储空间。或者，手机还可以先对待恢复数据进行加密，以提高手机拷贝上述待恢复数据时的安全性。
S406、手机执行恢复出厂设置的操作。
在步骤S406中，手机可沿用现有的恢复出厂设置的方法，在recovery模式下对ROM中的data分区进行格式化，格式化之后data分区内的文件和文件夹均被擦除。另外，在recovery模式下手机还可以将操作系统的各项设置恢复初始的默认设置，使得手机被恢复为出厂售卖时的状态。
S407、手机恢复出厂设置后，将上述目标存储空间内的待恢复数据重新恢复至手机内。
手机恢复出厂设置后可显示如图10所示的对话框1001，以提示用户将恢复出厂设置之前备份的待恢复数据重新恢复在恢复出厂设置之后的手机中。那么，如果用户确认恢复上述待恢复数据，则手机可从上述目标存储空间中读取待恢复数据，并将待恢复数据拷贝至ROM的data分区内。
在本申请的一些实施例中，手机将上述待恢复数据备份至目标存储空间后，可建立目标存储空间中的备份的待恢复数据与data分区中的待恢复数据之间的对应关系。这样，在步骤S407中，手机在data分区中恢复原始的待恢复数据时，可按照该对应关系将每一项备份的待恢复数据恢复至data分区中相应的位置。
例如，原存储路径(如data分区中的存储路径)A下的名称为a的待备份数据，被存储到目标存储空间中的位置B，则记录“A\a”与“B\a”的对应关系。恢复时，可根据该对应关系，将目标存储空间中的位置B的名称为a的数据，恢复到原存储路径A下，名称仍为a。
再例如，原存储路径A下的名称为a的待备份数据，被存储到目标存储空间中的位置B，并被改名为b，则记录“A\a”与“B\b”的对应关系。恢复时，可根据该对应关系，将目标存储空间中的位置B的名称为b的数据，恢复到原存储路径A下，并将名称改为a。
示例性的，手机可以将备份待恢复数据时创建的备份清单作为上述对应关系。大多数情况下，手机在目标存储空间中备份待恢复数据时不会修改待恢复数据的名称和待恢复数据内的存储结构。例如，手机在备份data分区中“app”文件夹内名称为“weibo.com”的文件夹时，还是以“weibo.com”作为该文件夹的名称将该文件夹中的内容拷贝至目标存储空间中。在恢复该文件夹时，手机可按照备份清单中记录的存储路径，将目标存储空间中存储的微博APP的文件夹“weibo.com”以及淘宝APP的文件夹“taobao.com”拷贝至ROM的data分区中名称为“app”的文件夹内。当然，如果data分区被格式化后没有名称为“app”的文件夹，则手机可先创建名称为“app”的文件夹，再将微博APP的文件夹“weibo.com”以及淘宝APP的文件夹“taobao.com”拷贝至data分区中新创建的名称为“app”的文件夹内。此时，如图11所示，被恢复的微博APP和淘宝APP将重新显示在桌面1101中。由于恢复出厂设置前后微博APP和淘宝APP的文件夹中的数据均没有发生变化，因此， 微博APP和淘宝APP中的设置等功能均未发生变化，使得用户可以在恢复出厂设置前后能够感受到无缝衔接的操作体验。
又或者，上述对应关系也可以是手机在备份待恢复数据时新创建的对应列表。例如，手机在备份data分区中“aa”文件夹中名称为002的文件时，将该文件的名称修改为001后存储在目标存储空间中。那么，手机可在上述对应列表中记录目标存储空间中名称为“001”的文件对应的是data分区中“aa”文件夹中名称为002的文件。这样，手机在后续向data分区内恢复待恢复数据时，即使待恢复数据在目标存储空间存储时名称被修改，或者待恢复数据内的存储结构改变，手机仍然能够根据上述对应列表将目标存储空间中的待恢复数据恢复至data分区内。
又或者，手机恢复出厂设置后可显示如图12所示的待恢复数据列表1201，该待恢复数据列表1201中包括用户在步骤S403中选中的一项或多项待恢复数据。用户可以从待恢复数据列表1201中选择将哪些待恢复数据重新恢复在恢复出厂设置后的手机中。也就是说，用户既可以在待恢复数据时选择具体备份哪些数据，也可以在恢复数据时选择具体恢复哪些数据，从而提高手机在恢复出厂设置时人机交互的友好性。
当然，手机恢复出厂设置后，也可以自动将目标存储空间内的待恢复数据恢复至data分区。例如，手机可以在recovery模式下将目标存储空间内的待恢复数据拷贝至data分区。又或者，如果手机在步骤S405中将上述待恢复数据备份至ROM中新创建的新分区内，则手机退出recovery模式时新分区内的待恢复数据不会被清除。那么，手机也可以退出recovery模式后重新进入正常模式(normal mode)，并在正常模式下将目标存储空间内的待恢复数据拷贝至data分区，本申请实施例对此不做任何限制。
另外，手机在recovery模式下将目标存储空间内的待恢复数据重新恢复至data分区之后，可退出recovery模式并进入正常模式(normal mode)。例如，手机接收到用户确认重启手机的操作后，可自动关机，再自动开机后进入normal模式。由于手机在recovery模式下已经将目标存储空间中的待恢复数据恢复至data分区，因此，如图11所示，手机进入normal模式后被恢复的微博APP和淘宝APP将重新显示在桌面1101中。
又或者，如果手机在步骤S405中将上述待恢复数据备份至ROM中新创建的新分区内，则手机退出recovery模式时新分区内的待恢复数据不会被清除。因此，手机也可以在退出recovery模式并进入normal模式之后提示用户将恢复出厂设置之前备份的待恢复数据重新恢复在恢复出厂设置之后的手机中，本申请实施例对此不做任何限制。
当然，如果用户确认不再恢复上述待恢复数据，则手机可将上述目标存储空间中存储的待恢复数据删除，以释放手机内的存储资源，此时手机完全恢复到出厂售卖时的状态。例如，手机可以多次显示图10或图12所示的弹框提示用户恢复待恢复数据，如果用户多次(例如连续3次)拒绝恢复待恢复数据，则手机可删除目标存储空间中存储的待恢复数据。又或者，手机可以将上述目标存储空间中存储的待恢复数据保存一定时间期限(例如3天)，如果3天内没有接收到用户执行恢复待恢复数据的操作，则手机可删除目标存储空间中存储的待恢复数据。
S408、手机删除目标存储空间中的待恢复数据。
在步骤S408中，当手机重新将上述待恢复数据恢复至手机中ROM的data分区后，可将存储在目标存储空间的待恢复数据删除，避免目标存储空间内的待恢复数据占用手机 的系统资源。另外，如果上述目标存储空间是手机在备份上述待恢复数据时动态创建的新分区(例如上述resume分区)，则手机也可以将该新分区销毁，避免该新分区占用手机的系统资源。
示例性的，如果resume分区是手机从ROM的data分区中创建的，则手机将resume分区销毁后，可将resume分区所占用的存储资源与当前的data分区合并，使得手机内的data分区可以还原至手机创建resume分区之前的状态。
另外，如果手机将待恢复数据存储在手机的RAM中，由于RAM断电后其内部数据会被自动擦除，因此，当手机退出recovery模式重启手机时可自动删除RAM中的待恢复数据。
可以看出，在本申请实施例提供的整个恢复出厂设置的过程中，手机可以在恢复出厂设置之前将用户需要备份的待恢复数据备份在手机的内部存储空间中，并在恢复出厂设置之后再从内部存储空间中重新恢复该待恢复数据。整个数据备份和数据恢复的过程无需依赖Wi-Fi网络环境、云服务器等外部资源，使得数据在备份和恢复过程中更加稳定和安全，用户在恢复出厂设置时的操作也更为简单便捷。
