终端备份和恢复方法 技术领域
本发明涉及计算机技术领域, 尤其涉及终端备份及恢复方法。 背景技术
随着计算机技术的发展,在各种计算机终端中安装的程序也越来 越多。 就个人计算机终端而言, 一般来说, 其中安装有操作系统程序 和一些应用程序, 这些程序相互配合工作, 满足用户各种操作需求。 但在终端运行一段时间后, 由于病毒的破坏或自身垃圾文件的产 生, 很多程序会运行的越来越緩慢, 甚至由于文件损坏造成无法正常 开启或使用。 针对这种情况, 出现了 Ghost等系统备份还原工具, 将 整个分区的数据全部备份出来,在需要的时候再将备份数据还原到原 分区。 但此类备份还原工具的执行速度相当緩慢,由于其备份原理是逐 扇区的将原数据克隆备份,恢复还原时将整个备份数据再原封不动的 写回, 因此, 不仅要求较大的存储空间, 而且非常耗时, 如果运用于 基于网络的存储备份, 则其发送的数据量相当大。

下面结合附图和具体的实施方式对本发明作进一步的描述。 下面结合附图, 对本发明的实施例进行详细说明。
如图 1所示,为根据本发明的一个实施例的一种基于云架构的终 端对象分类备份方法流程图, 包括:
步骤 101 : 在终端侧提供一用户界面, 以根据预设展示策略提供 不同备份类别供用户选择, 其中不同备份类别包含不同备份对象; 步骤 102: 根据用户选定的备份类别及对象, 在终端侧根据预设 备份策略将所述备份对象所对应的终端文件在云端服务器进行备份。 其中, 可以在所述云端数据库中预置一文件数据库, 所述文件数 据库中存储有不同终端文件及其唯一性特征信息; 而所述终端侧可以 根据预设备份策略将所述备份对象所对应的终端文件的唯一性特征 信息在云端服务器进行备份存储。
例如, 所述备份类别可以是当前整个系统, 该类别包含的备份对 象包括操作系统的核心文件及已安装的应用程序;所述云端服务器中 预置的文件数据库中存储有不同操作系统所包含的核心文件及初始 注册表文件, 及所述核心文件的唯一性特征信息, 并存储有不同应用 程序的唯一性特征信息及安装文件。
如图 2所示,为根据本发明的一个实施例的对当前系统进行备份 的流程示意图, 包括:
步骤 201 : 根据终端 /用户的备份请求, 获取终端侧当前操作系统 的核心文件及当前已安装的应用程序的唯一性特征信息,并发送至云 端服务器备份存储;
步骤 202: 所述云端服务器根据所述文件数据库确定该执行备份 的终端 /用户与所述备份的唯一性特征信息所代表的操作系统核心文 件之间的对应关系,及与备份的已安装的应用程序的唯一性特征信息 所代表的应用程序安装文件之间的对应关系。
所述操作系统核心文件的唯一性特征信息可以是该文件的签名 信息或 MD5值等可唯一区别的信息; 所述应用程序的唯一性特征信 息可以是该程序的名称及版本号或 ID号等可唯一区别的信息。
此外,所述文件数据库中进一步存储有不同操作系统的初始注册 表文件;所述云端服务器根据所述文件数据库确定该执行备份的终端 /用户与初始注册表文件之间的对应关系。
云端服务器的概念, 目前已经得到了相当大的发展和运用,例如, 对于病毒特征库的建立, 可以设置于云端服务器, 客户端只需要上传 本地文件特征即可与云端服务器中的病毒特征进行比较,从而运用黑 名单查杀病毒。
同理, 本发明的实施例在云端服务器中预置一文件数据库, 存储 有不同类别不同版本的操作程序的核心文件,及核心文件的唯一性特 征信息, 以及不同应用程序的安装文件。
通过长期的积累,在云端服务器可以建立一个包含众多常用程序 文件的庞大的文件数据库,例如一些常用的操作系统以及一些常用的 应用程序都可以收录于其中。
而通过实际分析, 是可以获知各种程序 (例如, 操作系统)其原 始的核心文件的范围。 例如, 对于操作系统而言, 所述核心文件可以 是该操作系统在安装后于终端中释放的初始文件;或者是那些维持操 作系统运行所必不可少的主文件;或者也可以是指那些同样的操作系 统程序被安装于不同终端并运行一段时间后的仍保持同样内容的共 性文件。
核心文件的范围选择,可以根据不同程序(例如,操作系统程序) 以及不同的备份要求而确定。 显然, 备份的核心文件的范围越大, 则 还原后的程序也越忠实于终端备份时的样态; 而备份的核心文件的范 围越小, 则备份的数据量越小, 还原后的程序越接近该操作系统程序 在安装后的初始样态。 但很明显, 那些可能在程序运行一段时间后所 产生的一些垃圾文件或被病毒等恶意程序所注入的一些有害文件不 会被包含在核心文件内。
对运行于不同终端中的相同操作系统程序来说 ,其核心文件的内 容大部分是相同的, 受到破坏的文件毕竟是少数, 因此, 这就为复用 云端文件数据库文件提供了基础。
对于运行于终端中的同一操作系统程序所包含的核心文件,如果 没有被破坏,则其签名信息是与云端数据库中的该核心文件的签名信 息是一致的。 因此, 将终端中该操作系统程序的该核心文件的签名信 息保存于服务器侧,就可以起到将该核心文件备份于服务器侧相同的 目的, 因为具有相同签名信息的相同核心文件已经预存于数据库中 了。 只有对于那些签名信息不一致的核心文件, 才需要由该终端侧实 际上传至服务器中存储。
如此,该终端只需要上传备份的操作系统程序的核心文件的唯一 性特征信息就完成了备份操作系统的工作,云端服务器即可以根据该 唯一性特征信息确定该终端备份的操作系统核心文件是哪些。
如图 3所示, 在终端 301中运行着欲备份的操作系统程序 1 , 其 包含有核心文件 1、 核心文件 2、 核心文件 3 , 以及垃圾文件 4 , 对应 的唯一性签名信息为文件签名 1、 文件签名 2及文件签名 3 , 以及文 件签名 4。 在服务器 302中数据库记录了操作系统程序 1的核心文件 1、 核心文件 2及核心文件 3 , 对应的唯一性签名信息为文件签名 1、 文件签名 2及文件签名 3。 而在服务器侧备份的内容仅需要记录该终 端或用户标识 201及备份的操作系统程序 1的文件签名 1、 文件签名 2及文件签名 3。 很明显, 终端备份的数据内容很少, 但足以在服务 器侧确定该终端需要备份的程序数据。 而且, 由于备份的都是程序的 核心文件, 将一些可能的垃圾文件排除在外, 这不仅减少了备份数据 量, 而且在恢复后可以还原一个干净的程序。
所述终端侧可以根据一个预置的规则表中记录的该欲备份的操 作系统程序的核心文件名称,获取欲备份的操作系统程序的核心文件 的唯一性特征信息。 这个规则表可以是终端侧自带的, 例如在该操作 系统程序执行安装时在终端侧记录的该程序所释放的初始文件;或通 过扫描终端本地文件列表, 根据程序名称及版本向服务器端索取, 而 服务器端则存储有众多常用程序的核心文件规则表。可以通过该规则 表灵活控制核心文件的范围大小。 文件, 如图 4所示, 为根据本发明的一个实施例的在终端侧获取欲备 份的操作系统程序的核心文件的唯一性特征信息的流程图, 包括: 步骤 401 : 终端侧将当前操作系统的唯一性特征信息发送至云端 服务器;
步骤 402: 所述云端服务器根据文件数据库记录的不同操作系统 的唯一性特征信息确定该操作系统及其所对应包含的核心文件,并将 核心文件的名称发送至该终端侧; 统的核心文件的唯一性特征信息。
其中操作系统的唯一性特征信息可以是该操作系统程序的名称 及版本号或程序 ID等可以唯一的确定该程序对象的信息。
根据本发明的实施例,如果所述云端服务器在所述文件数据库中 无法确定与所述终端侧发送的唯一性特征信息对应的核心文件,则说 明终端侧该核心文件的签名信息与服务器侧数据库中的该核心文件 的签名信息不一致, 其有可能是已经被用户修改过的个性文件, 这时 可以由所述终端侧将与该唯一性特征信息对应的本地核心文件发送 至云端服务器备份存储。
此外, 还可以定义一些该操作系统程序的非核心文件, 例如一些 静态配置的文件, 或记录用户数据的文件, 由于这些文件尽管不影响 程序的运行, 但可能记录了用户的使用习惯, 因此, 也可以在备份时 提取出来。 这样, 可以由所述终端侧获取所述欲备份的程序的当前非 核心文件, 并发送至云端服务器备份存储。 或者进一步获得非核心文 件的唯一性特征信息一并备份存储。非核心文件的确定可以同样采取 规则表的形式。
对于大部分的程序而言,其安装后释放的文件都会是在同一个目 录路径下, 也就是说其相对位置关系并不重要, 但对于一些较为复杂 的程序来说, 例如操作系统程序, 可能嵌套有多层目录的情况, 这时 可以将核心文件之间的相对位置关系信息保存于文件数据库中;也可 以是由所述终端侧将所述欲备份程序的核心文件之间的相对位置关 系信息发送至云端服务器存储。
同样, 对于非核心文件来说, 终端侧也可以将当前核心文件与非 核心文件之间的相对位置关系发送至云端服务器存储。
而对于终端侧的已安装应用程序,只需要备份该应用程序的唯一 性特征信息, 例如该应用程序的名称及版本号或 ID号即可, 由于在 服务器侧文件数据库中存储有不同应用程序的唯一性特征信息及其 安装文件, 因此, 通过获知终端侧备份的唯一性特征信息, 即可确定 对应的安装文件, 以便恢复时使用。
而如果所述云端服务器在所述文件数据库中无法确定与所述终 端侧发送的唯一性特征信息对应的应用程序安装文件,则由所述终端 侧将与该唯一性特征信息对应的本地应用程序文件及对操作系统注 册表的修改信息发送至云端服务器备份存储。 服务器备份存储, 以便恢复时可以将用户数据一并还原。
根据本发明另一实施例, 所述备份类别可以是应用程序, 该类别 包含的备份对象包括终端已安装的应用程序;所述云端服务器中预置 的文件数据库中存储有不同应用程序的唯一性特征信息及安装文件。
如图 5所示,为根据本发明的一个实施例的备份应用程序的流程 示意图, 包括:
步骤 501 : 根据终端 /用户的备份请求, 获取终端侧当前已安装的 应用程序的唯一性特征信息, 并发送至云端服务器备份存储;
步骤 502: 所述云端服务器根据所述文件数据库确定该执行备份 的终端 /用户与所述备份的唯一性特征信息所代表的应用程序安装文 件之间的对应关系。
根据本发明又一实施例,所述备份类别可以是与应用程序有关的 用户数据, 如浏览器的收藏夹设置, 或邮件程序的用户收件夹等, 该 类别包含的备份对象包括该应用程序的用户数据文件, 在备份时, 可 以根据终端 /用户的备份请求, 获取用户选定的应用程序的用户数据 并发送至云端服务器备份存储。
如图 6所示,为根据本发明的一个实施例的基于云架构的终端对 象分类恢复方法流程图, 包括:
步骤 601 : 在终端侧提供一用户界面, 以根据预设展示策略提供 不同的已备份类别供用户选择恢复,其中不同的已备份类别包含不同 的已备份对象;
步骤 602: 根据用户选定的已备份类别及对象, 在云端服务器确 定该终端 /用户已经备份的与所述备份对象相对应的文件, 并根据预 设恢复策略, 利用所述已备份文件在终端侧执行对应的恢复。
其中, 所述云端数据库中可以预置一文件数据库, 所述文件数据 库中存储有不同终端文件及其唯一性特征信息;所述云端服务器可以 根据终端 /用户已备份的唯一性特征信息在文件数据库中确定该终端 / 用户已经备份的与所述备份对象相对应的文件。
根据本发明的实施例, 所述已备份类别包括当前系统, 该类别包 含的已备份对象包括操作系统的核心文件及已安装的应用程序;所述 已经备份的与所述备份对象相对应的文件包括该操作系统核心文件 及已安装应用程序的唯一性特征信息。
如图 7所示,为根据本发明的一个实施例的当前系统恢复的流程 示意图, 包括:
步骤 701 : 将云端服务器侧已经备份的该终端的操作系统的核心 文件的唯一性特征信息与终端侧本地操作系统的文件的当前唯一性 特征信息进行匹配;
步骤 702: 在终端侧将匹配不成功的当前唯一性特征信息对应的 文件删除,并由云端服务器侧将匹配不成功的唯一性特征信息对应的 文件发送至该终端侧对应存储;
步骤 703 : 由云端服务器根据所述已经备份的在终端侧已安装的 应用程序的唯一性特征信息,使用预存的对应应用程序的安装文件在 终端侧执行安装,
其中, 所述云端服务器中预置有一文件数据库, 存储有不同操作 系统所包含的核心文件及初始注册表文件,及所述核心文件的唯一性 特征信息, 并存储有不同应用程序的唯一性特征信息及安装文件。
所述文件数据库中进一步可以存储有不同操作系统的初始注册 骤之前, 进一步包括: 由云端服务器将文件数据库中存储的与终端侧 操作系统对应的初始注册表文件发送至终端侧对应存储。
如果在备份时选定的核心文件中包含注册表文件, 那么, 由于注 册表文件的个性化相当强,往往在运行一段时间后就会与最初的注册 表文件产生差异, 这样, 在备份时由于终端侧注册表文件的唯一性特 征信息与文件数据库中的核心文件的唯一性特征信息不一样,无法据 此确定文件数据库中对应的核心文件 , 因此就会要求将终端侧注册表 文件上传至服务器备份存储, 并在恢复时将其再发送回终端侧。
但由于在备份时该终端侧的注册表可能已经包含有垃圾数据,如 果再将其原样恢复的话, 并不能带来性能的改善, 因此, 可以在文件 数据库中进一步存储该操作系统的初始的干净的注册表数据,在恢复 时,可以将操作系统的文件恢复后再将该初始注册表数据发送至终端 侧, 取代其当前的注册表数据, 这样, 就可以为终端侧带来一个干净 的注册表文件, 并在此基础上安装应用程序。
更进一步地,可以在备份时选定的核心文件中就不包含注册表文 件, 而是在恢复时统一使用初始注册表, 则可以更快速地进行备份和 恢复, 同时带来操作系统的性能恢复。
云端服务器根据终端侧的用户登录信息就可以获知当前用户,也 就可以获知该用户曾经备份过的数据。 对于大部分终端 /用户来说, 在收到其恢复请求后,服务器就可以确定该用户备份过的唯一性特征 信息。 如图 2所示, 用户终端 -终端侧备份的操作系统程序-终端侧核 心文件及其签名信息 -所备份的核心文件签名信息-云端文件数据库 中记录的签名信息-数据库中的核心文件, 这些对应关系都通过唯一 性特征信息相互联系起来。
在恢复时,可以将云端服务器侧已经备份的该操作系统的核心文 件的唯一性特征信息与该终端侧本地对应程序的全部文件的当前唯 一性特征信息进行匹配。 如此, 终端侧不需要确定操作系统核心文件 的范围,凡是与已经备份的签名信息不一致的本地程序文件全部可以 删除, 包括本地一些与该程序有关的垃圾文件以及因为文件受损或修 改后导致签名信息变化的文件; 而在服务器侧, 可以成功匹配的已备 份的签名信息代表在终端侧对应文件完好无损,而无法成功匹配的已 备份签名信息表示终端侧原文件已经改变,这就需要利用文件数据库 中的对应文件发送至终端侧存储。由于该已经改变的原文件已经因为 无法成功匹配而被删除, 因此, 数据库中的对应文件就发送至终端侧 取代了原文件。 由此可见, 本发明实施例的恢复方式是基于特征比对 的, 只有签名信息改变的文件才需要实际从服务器传送至终端, 这就 极大了的降低了数据传输量,而且也删除了终端侧在程序运行过程中 产生的垃圾文件, 改善了终端系统性能。
在恢复时,还可以是将云端服务器侧已经备份的操作系统程序的 核心文件的唯一性特征信息与该终端侧本地对应程序的核心文件的 当前唯一' )·生特征信息进行匹配。
而对于核心文件之间的唯一性特征信息匹配的步骤,可以是由终 端侧执行, 也可以是由服务器侧执行。
例如,可以由云端服务器将所述已备份操作系统程序的核心文件 的唯一性特征信息发送至终端侧; 然后, 终端侧将接收到的核心文件 的唯一性特征信息与本地对应程序的核心文件的当前唯一性特征信 息进行匹配。 或者, 由终端侧将欲恢复的操作系统程序的核心文件的当前唯一 性特征信息发送至云端服务器; 然后, 由所述云端服务器将收到的所 述当前唯一性特征信息与存储的由该终端已经备份过的该操作系统 程序的核心文件的唯一性特征信息进行匹配。
只进行核心文件之间的匹配可以减少终端侧删除文件的范围,从 而可以更精确地保留终端侧个性文件,或与非核心文件的还原互为补 充。
在服务器侧如果还备份有操作系统的非核心文件,则可以进一步 由云端服务器将终端侧已备份的该操作系统程序的非核心文件发送 至终端侧对应存储。
如果云端服务器备份了非核心文件以及其对应的唯一性特征信 息,则可以将云端服务器侧已备份的该操作系统程序的非核心文件的 唯一性特征信息与该终端侧本地对应程序的文件的当前唯一性特征 信息进行匹配, 如果匹配一致, 则说明文件完好, 不需要替换, 如果 匹配不一致, 则可以将终端侧匹配不成功的非核心文件删除, 并再将 而对于程序文件在终端侧的存储路径,可以按照默认安装路径存 储, 也可以通过动态搜索技术获知该程序在终端侧的安装路径, 实际 上, 一般只要终端侧有一个核心文件就可以获知该程序的安装路径。
此外,所述终端侧还可以根据已在云端服务器记录的所述核心文 件之间的相对位置关系对核心文件进行存储;或根据已在云端服务器 件进行存储。
在某些特殊情况下, 如果在所述终端本地没有找到所述对应程 序, 则说明操作系统可能已被更换, 这时可以将在所述云端服务器中 与已经备份的唯一性特征信息相对应的核心文件发送至该终端侧对 应存储。
此外, 在恢复时, 如果终端侧需要获知该程序的核心文件范围, 名称;或根据所述云端服务器中的文件数据库中记录的所述程序的核 而对于应用程序的恢复来说,就是利用服务器侧文件数据库中的 安装文件在终端侧本地执行覆盖安装,或者先将该应用程序的配置文 件和用户数据在本地保存起来, 然后再执行安装, 安装后再将配置文 件和用户数据对应还原。
根据本发明的另一实施例, 所述备份类别可以包括应用程序, 该 类别包含的备份对象包括终端已安装的应用程序;所述已经备份的与 征信息。
在恢复时, 由云端服务器根据所述已经备份的在终端侧已安装的 应用程序的唯一性特征信息,使用预存的对应应用程序的安装文件在 终端侧执行安装, 而在所述云端服务器中预置有文件数据库, 存储有 不同应用程序的唯一性特征信息及安装文件。
根据本发明又一实施例,所述备份类别可以包括与应用程序有关 的用户数据, 该类别包含的备份对象包括该应用程序的用户数据文 件;所述已经备份的与所述备份对象相对应的文件或数据包括该应用 程序的用户数据文件;
恢复时,可以将已经备份的该应用程序的用户数据从云端服务器 发送至终端侧对应存储。
由此可见, 本发明的一个实施例由于在备份时提供了类别选项, 其中不同类别还包括不同的备份对象, 通过对类别和对象的选择, 实 现了仅对用户关注的部分进行备份和恢复, 方便了用户对终端的管 理。 同时, 本发明在备份时, 仅需要备份当前系统的特征信息, 而不 用实际备份文件内容, 因此,备份速度很快,传输的数据量大大减少; 而恢复时是基于差异比较的恢复,即如果核心文件的特征信息没有变 化, 则不需要恢复该文件, 只有特征信息发生变化的才需要从数据库 中下载相应文件, 因此, 恢复的速度也很快, 传输量很少。 此外, 由 于是基于差异比较的恢复, 因此, 与备份时的文件范围或内容存在差 异的垃圾文件等有害文件都可以被清除, 在恢复后提升了程序性能。
在本发明的另一方面, 还公开了另一种终端备份方法。 如图 8所 示, 公开了一种根据本发明的一个实施例的终端备份方法, 该方法包 括: 步骤 801 : 云端服务器预置有文件数据库, 所述文件数据库存储 不同程序所包含的核心文件及其唯一性特征信息;
步骤 802: 从终端接收预备份的程序的核心文件的唯一性特征信 息并存储在所述云端服务器;
步骤 803 : 所述云端服务器根据所述文件数据库确定所述终端与 预备份的程序的核心文件的唯一性特征信息所代表的核心文件之间 的对应关系。
上面的不同程序可以指操作系统、应用程序等可以安装在终端的 程序。
对于核心文件的唯一性特征信息可以是该文件的签名信息或 MD5 值等可唯一区别的信息; 对于应用程序的唯一性特征信息可以 是该程序的名称及版本号或 ID号等可唯一区别的信息。
另外,如果所述云端服务器在所述文件数据库中无法确定与从所 述终端接收的唯一性特征信息对应的核心文件,则将所述终端的与该 唯一性特征信息对应的本地核心文件进行备份存储。
任选地,所述云端服务器从所述终端接收预备份的程序的非核心 文件、 在注册表中的修改项、 核心文件之间的相对位置关系和 /或核 心文件与非核心文件之间的位置关系以进行备份存储。
