[発明を実施するための最良の形態] [Best Mode for Carrying Out the Invention]
以下、 本発明の実施の形態について図面に従って説明する。 しかしながら、 本 発明の技術的範囲はかかる実施の形態によって限定されるものではない。  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited by such an embodiment.
図 1は、 本発明の実施の形態における情報処理装置のプロヅク構成例である。 情報処理装置 1は、 C P U 1 0と少なくとも 2つの記憶媒体 1 2、 1 4を備え、 以下に説明する回復可能な情報と回復不可な情報が、 それそれ記憶媒体 1 2と記 憶媒体 1 4とに分けて格納される。 情報処理装置 1は、 例えば、 パーソナルコン ビュ一夕や携帯端末などの端末装置 (スタンドアローン装置、 ネヅトワーククラ イアント) 、 ネットワークサーバなどを含むコンピュータ装置である。  FIG. 1 is an example of a block configuration of an information processing apparatus according to an embodiment of the present invention. The information processing apparatus 1 includes a CPU 10 and at least two storage media 12 and 14. Recoverable information and non-recoverable information described below are stored in a storage medium 12 and a storage medium 14, respectively. And stored separately. The information processing device 1 is a computer device including, for example, a terminal device (stand-alone device, network client) such as a personal computer or a portable terminal, a network server, and the like.
回復可能な情報は、 例えば市販されている O S (オペレーティングシステム) やアプリケーションプログラムなど外部からインストールされる情報であって、 例えば、 C D— R OMなどの別の記憶媒体 2 0からの再ィンストールなどの手段 により回復可能なプログラムやデータなどの情報である。 また、 回復不可な情報 は、 ◦ Sやアプリケーションプログラムなどの実行により作成又は更新された情 報であって、 例えば、 ワープロソフトにより作成された文書データや、 各種 I D (電子メールアカウントも含む)、パスワードなどを含む設定ファイルなどュ一 ザのみが有する情報であって、 一旦消去されると、 再インストールなどの手段に より回復できない情報である。 Recoverable information is information that is externally installed, such as a commercially available OS (operating system) or application program. For example, information that can be recovered from another storage medium 20 such as a CD-ROM. means Information such as programs and data that can be recovered by Non-recoverable information is information created or updated by executing S or application programs, such as document data created by word processing software, various IDs (including e-mail accounts), Information that only the user has, such as a configuration file containing a password, etc., that cannot be recovered by means such as reinstallation once it has been deleted.
記'慮媒体 1 2は、 好ましくは、 揮発性記憶媒体であるワーク R AMであって、 記' It媒体 1 2に 0 Sやアプリケーションプログラムなどのプログラムを直接ィン ストールすることで、 C P U 1 0は、 言 3憶媒体 1 2に言 3憶されるプログラムを、 実行することができる。即ち、従来のように、プログラムを不揮発性記憶媒体(主 に、 磁気ディスク装置) にインストールせず、 当該プログラムを実行するワーク RAMに直接インストールすることで、 同じプログラムが複数の記憶媒体に重な つて記憶されることがないので、 記憶媒体の有効利用が図られる。  The storage medium 12 is preferably a work RAM, which is a volatile storage medium. By directly installing a program such as OS or an application program on the storage medium 12, the CPU 1 0 means that the program stored in the storage medium 1 2 can be executed. That is, by installing the program directly on the work RAM that executes the program without installing the program on a non-volatile storage medium (mainly, a magnetic disk device) as in the past, the same program can be duplicated on multiple storage media. Since the data is not stored, the storage medium is effectively used.
また、 揮発性記憶媒体 1 2には、 好ましくは、 バックアップ電源 1 6が与え られる。これにより、揮発性記憶媒体 1 2に対する情報処理装置 1の本体電源(図 示せず) からの電源供給が途切れても、 バヅクアップ電源 1 6による電源供給に 切り替わり、 揮発性記憶媒体 1 2には、 常時電源供給が行われ、 揮発性記憶媒体 1 2に記憶される情報は常時保持されている。 但し、 バックアップ電源 1 6の何 らかの故障により、 揮発性記憶媒体 1 2への電源供給が停止すると、 揮発性記憶 媒体 1 2に記憶されていた情報が消去される。 この場合、 ィン夕一フエース 1 8 を介して、 当該消去された情報と同じ情報を格納する外部記憶媒体 2 0より、 当 該消去された情報を再ィンストールすることにより、 消去された情報を回復させ ることができる。  The volatile storage medium 12 is preferably provided with a backup power supply 16. As a result, even if the power supply from the main unit power supply (not shown) of the information processing apparatus 1 to the volatile storage medium 12 is interrupted, the power supply is switched to the backup power supply 16 and the volatile storage medium 12 Power is always supplied, and the information stored in the volatile storage medium 12 is always held. However, if the power supply to the volatile storage medium 12 is stopped due to some failure of the backup power supply 16, the information stored in the volatile storage medium 12 is deleted. In this case, the erased information is re-installed from the external storage medium 20 that stores the same information as the erased information via the interface 18 so that the erased information is re-installed. It can be recovered.
一方、 記憶媒体 1 4は、 例えば、 不揮発性記憶媒体 (フラッシュメモリ、 磁 気ディスク装置など) である。 上述のように、 不揮発性記憶媒体 1 4は、 記憶を 保持するのに電源供給を維持する必要はないので、 電源供給が途切れても、 不揮 発性記憶媒体 1 4に記憶された情報は消滅しない。 不揮発性記憶媒体 1 4には、 情報処理装置の B 1 0 S、 記憶媒体 1 2に記憶されているプログラムの実行によ り作成又は更新されたデ一夕などの回復不可情報が記憶される。 そして、 本発明の実施の形態では、 情報処理装置内に格納される情報を、 回 復可能な情報か、 回復不可な情報かを判別して、 その判別結果に応じて、 情報をOn the other hand, the storage medium 14 is, for example, a nonvolatile storage medium (flash memory, magnetic disk device, etc.). As described above, since the nonvolatile storage medium 14 does not need to maintain the power supply to maintain the memory, even if the power supply is interrupted, the information stored in the nonvolatile storage medium 14 is not changed. Does not disappear. The non-volatile storage medium 14 stores non-recoverable information such as B 10 S of the information processing device and data created or updated by execution of a program stored in the storage medium 12. . Then, in the embodiment of the present invention, it is determined whether the information stored in the information processing apparatus is recoverable information or non-recoverable information, and the information is determined according to the determination result.
2つの記憶媒体 1 2、 1 4に分離して記憶する処理を行うための分離プログラム が提供される。分離プログラムは、あらかじめ〇 Sに組み込まれていてもよいし、 また単独のプログラムとして、 例えば外部記憶媒体 2 0からインストールされ、 揮発性記憶媒体 1 2に記憶されている。 なお、 分離プログラムをインストールす る前 (又は同時) にインストールされる O S、 及び分離プログラム自体を、 揮発 性記憶媒体 1 2に記憶させるように、 情報処理装置の B I 0 Sプログラムが設定 されている。 A separation program is provided for performing a process of separating and storing the two storage media 12 and 14 separately. The separation program may be incorporated in the storage device in advance, or may be installed as a single program from, for example, the external storage medium 20 and stored in the volatile storage medium 12. The BIOS program of the information processing device is set so that the OS installed before (or at the same time as) installing the separation program and the separation program itself are stored in the volatile storage medium 12. .
図 2は、 本発明の実施の形態における分離プログラムの処理フローチャート である。 情報処理装置の電源が投入されると、 o s、 アプリケーションプログラ ム、 分離プログラムは、 ワーク: RAMである揮発性記憶媒体 1 2に記憶されてい るので、 各プログラムはすぐに起動状態となる。分離プログラムは、 起動状態に おいて、 記憶媒体に記憶されようとする情報を監視し、 その情報が、 インスト一 ルされる情報か、 O Sや他のアプリケーションプログラムの実行により作成又は 更新される情報かに基づいて、記憶されようとしている情報が回復可能な情報か、 回復不可な情報かを判別する。 即ち、 分離プログラムは、 インスト一ルされる情 報を回復可能な情報と判断し、 アプリケーションプログラムにより新規作成又は 更新される情報を回復不可な情報と判断する。  FIG. 2 is a processing flowchart of the separation program according to the embodiment of the present invention. When the power of the information processing apparatus is turned on, the OS, the application program, and the separation program are stored in the volatile storage medium 12, which is work: RAM, so that each program is immediately activated. The separation program monitors information to be stored in the storage medium in the running state, and the information is information that is installed or information that is created or updated by executing the OS or other application programs. Then, it is determined whether the information to be stored is recoverable information or non-recoverable information. That is, the separation program determines that the installed information is recoverable information, and determines that the information newly created or updated by the application program is irrecoverable information.
図 2 ( a ) において、 例えば、 ユーザの操作により、 アプリケーションプロ グラムの実行中に編集された新規又は更新されたデ一夕の保存が指示されたり、 ァプリケ一ションプログラムによる自動保存機能により、 アプリケ一ションプロ グラムは、 O Sに対してデータ書き込み要求を出力する (S 1 0 ) 。 デ一夕書き 込み要求では、 デ一夕が記憶される記憶媒体が指定される。 O Sは、 当該データ 書き込み要求を、 指定された記憶媒体のドライバに転送する。  In FIG. 2 (a), for example, an instruction to save a new or updated data edited during execution of an application program is given by a user operation, or an application program is automatically saved by an application program. One of the option programs outputs a data write request to the OS (S10). In the data write request, a storage medium in which the data is stored is specified. OS transfers the data write request to the driver of the specified storage medium.
分離プログラムは、 O Sから出力されたデータ書き込み要求をドライバが取 得する前に取得する (S 1 1 ) 。 そして、 分離プログラムは、 指定された記憶媒 体をチェヅクし、 指定された記憶媒体を変更する必要があるか否か判定する (S 1 2 ) 。指定された記憶媒体が、 揮発性記憶媒体 1 2である場合は、 データ書き 込み要求で指定される記憶媒体を、不揮発性記憶媒体 14に変更して(S 13)、 不揮発性記憶媒体 14のドライバ 14 aに、 当該デ一夕書き込み要求を転送する (S 14) 。 ドライノ' 14aは、 OSからの指示に従って記憶媒体 14にァクセ スするプログラムであって、 OSに組み込まれているか、 回復可能な単体プログ ラムとしてあらかじめ記憶媒体 12にインストールされている。 ドライノ 14 a は、 そのデータ書き込み要求に従って、 デ一夕を不揮発性記憶媒体 14に記憶す る(S 15)。これにより、回復不可な情報であるプログラムの実行により作成 - 更新されたデータが、 不揮発性記憶媒体 14に記憶されることが保証される。 なお、 デ一夕書き込み要求で指定される記憶媒体が、 元々不揮発性記憶媒体 14である場合は、 そのまま不揮発性記憶媒体 14のドライバにデ一夕書き込み 要求を転送する。 The separation program acquires the data write request output from the OS before the driver acquires it (S11). Then, the separation program checks the specified storage medium and determines whether or not the specified storage medium needs to be changed (S12). If the specified storage medium is a volatile storage medium 1 2 The storage medium specified by the write request is changed to the nonvolatile storage medium 14 (S13), and the data write request is transferred to the driver 14a of the nonvolatile storage medium 14 (S14). The dryno 14a is a program that accesses the storage medium 14 according to an instruction from the OS, and is incorporated in the OS or installed in the storage medium 12 in advance as a recoverable single program. The dryno 14a stores the data in the nonvolatile storage medium 14 according to the data write request (S15). As a result, it is guaranteed that data created and updated by execution of the program, which is unrecoverable information, is stored in the nonvolatile storage medium 14. If the storage medium designated by the data write request is originally the nonvolatile storage medium 14, the data write request is transferred to the driver of the nonvolatile storage medium 14 as it is.
また、 図 2 (b) において、 新しいアプリケーションプログラムがインスト ールされる場合、 分離プログラムは、 OSから出力されるインストール要求を取 得する (S 20) 。 そして、 分離プログラムは、 指定された記憶媒体をチェック し、 インスト一ル要求で指定される記憶媒体を変更する必要があるか否か判定す る (S 21) 。 そして、 指定された記憶媒体が、 不揮発性記憶媒体 14である場 合は、 インストール要求で指定される記憶媒体を、 揮発性記憶媒体 12に変更し て (S 22) 、 揮発性記憶媒体 12のドライバ 12 aに、 当該インストール要求 を転送する (S 23) 。 ドライノ、' 12 aは、 ドライバ 14 a同様に、 OSからの 指示に従って記憶媒体 12にアクセスするプログラムであって、 OSに組み込ま れているか、 回復可倉 な単体プログラムとしてあらかじめ記憶媒体 12にインス トールされている。 ドライノ I 2 aは、 インストール要求に従って、 アプリケ一 シヨンプログラムを揮発性記憶媒体 12に記憶する (S 24) 。 これにより、 回 復可能な情報であるアプリケーションプログラムが、 揮発性記憶媒体 12に記憶 される。  In FIG. 2 (b), when a new application program is installed, the separation program obtains an installation request output from the OS (S20). Then, the separation program checks the specified storage medium and determines whether it is necessary to change the storage medium specified by the installation request (S21). If the specified storage medium is the non-volatile storage medium 14, the storage medium specified by the installation request is changed to the volatile storage medium 12 (S22), and the storage medium of the volatile storage medium 12 is changed. The installation request is transferred to the driver 12a (S23). Like the driver 14a, the dryino, '12a, is a program that accesses the storage medium 12 in accordance with instructions from the OS. Have been. The dryino I2a stores the application program in the volatile storage medium 12 according to the installation request (S24). Thus, the application program, which is recoverable information, is stored in the volatile storage medium 12.
なお、 インストール要求で指定される記憶媒体が、 元々揮発性記憶媒体 12 である場合は、 分離プログラムは、 そのまま揮発性記憶媒体 12のドライバにィ ンストール要求を転送する。  If the storage medium specified in the installation request is originally the volatile storage medium 12, the separation program transfers the installation request to the driver of the volatile storage medium 12 as it is.
また、 上述の実施の形態において、 分離プログラムは、 記憶コマンドの種類 (インストー^/要求か、 デ一夕書き込み要求か) により、 記憶されようとしてい る情報が回復可能な情報か、 回復不可な情報かを判別したが、 判別方法はこれに 限られない。 例えば、 記憶されようとしている情報の拡張子に基づいて判別して もよい。 分離プログラムは、 あらかじめ回復可能な情報に対応する拡張子と回復 不可な情報に対応する拡張子の情報を有し、 拡張子の種類に基づいて、 回復可能 な情報か、 回復不可な情報を判別してもよい。 Further, in the above-described embodiment, the separation program has the type of the storage command. (Install / request or overnight write request), it is determined whether the information to be stored is recoverable information or non-recoverable information, but the determination method is not limited to this. For example, the determination may be made based on the extension of the information to be stored. The separation program has information on the extension corresponding to the recoverable information and the extension corresponding to the unrecoverable information in advance, and determines whether the information is recoverable or unrecoverable based on the type of the extension. May be.
[産業上の利用の可能性] [Possibility of industrial use]
以上説明したように、 本発明の情報処理装置によれば、 記憶媒体に格納され るべき情報 (プログラム (O S及びアプリケーション) ゃデ一夕) を回復可能な 情報と回復不可な情報とに分離して、 それそれ異なる記憶媒体に格納する。 回復 可能な情報をワーク RAMに記憶することで、 回復可能な情報を 2つの記憶媒体 に重複して記憶する必要がなくなるので、 記憶媒体の有効利用が実現される。 本発明の保護範囲は、 上記の実施の形態に限定されず、 特許請求の範囲に記載 された発明とその均等物に及ぶものである。  As described above, according to the information processing apparatus of the present invention, information to be stored in a storage medium (program (OS and application) data) is separated into recoverable information and non-recoverable information. And store them on different storage media. Storing the recoverable information in the work RAM eliminates the need to store the recoverable information in two storage media redundantly, thereby realizing effective use of the storage media. The protection scope of the present invention is not limited to the above embodiments, but extends to the inventions described in the claims and their equivalents.
