+# Backup Tool
+
+## 1. Overview
+
+The IoTDB Full Backup Tool is designed to create a full backup of a single IoTDB node’s data via hard links to a specified local directory. The backup can then be directly started and joined to the original cluster. The tool offers two modes: **Quick Mirror Mode** and **Manual Backup Path Mode**.
+
+> **Notes**:
+>
+> * **Stop the IoTDB service before starting the backup**.
+> * The script runs in the background by default, and logs are saved to log files during execution.
+
+
+## 2. Backup Modes
+
+### 2.1 Mode 1: Quick Mirror Mode
+
+#### Usage
+
+```bash
+backup.sh/backup.bat -quick -node xxx 
+# Optional values for xxx are shown in the following examples
+
+backup.sh/backup.bat -quick -node 
+# Back up all nodes to the default path 
+
+backup.sh/backup.bat -quick -node all 
+# Back up all nodes to the default path 
+
+backup.sh/backup.bat -quick -node confignode 
+# Back up only the ConfigNode to the default path 
+
+backup.sh/backup.bat -quick -node datanode 
+# Back up only the DataNode to the default path
+```
+
+#### Parameter Descriptions
+
+| **Parameter** | **Description**                                                                                                                                                                                                                             | **Required** |
+| ----------------------- |---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| ---------------------- |
+| `-quick`          | Enables Quick Mirror Mode.                                                                                                                                                                                                                  | No                   |
+| `-node`           | Specifies the node type to back up. Options: `all`, `datanode`, or `confignode`. Default: `all`. <br>`all`: Back up both DataNode and ConfigNode. <br>`datanode`: Back up only the DataNode. <br>`confignode`: Back up only the ConfigNode. | No                   |
+
+**Process Details**:
+
+1. Check if the `_backup` folder already exists in the current IoTDB directory or paths specified in the configuration file. If it exists, the tool exits with the error: `The backup folder already exists`.
+> When the backup folder already exists, you can try the following solutions:
+> * Delete the existing _backup folder and retry the backup.
+> * Modify the backup path to avoid conflicts.
+
+2. Create hard links from the original `dn_data_dirs` paths to the corresponding `_backup` paths.
+    * Example: If `dn_data_dirs=/data/iotdb/data/datanode/data`, the backup data will be stored in `/data/iotdb/data/datanode/data_backup`.
+3. Copy other files from the IoTDB directory (e.g., `/data/iotdb`) to the `_backup` path (e.g., `/data/iotdb_backup`).
+
+
+### 2.2 Mode 2: Manual Backup Path Mode
+
+#### Usage
+
+```bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx  
+```
+
+#### Parameter Descriptions
+
+| **Parameter** | **Description**                                                                    | **Required** |
+| ----------------------- | -------------------------------------------------------------------------------------------- | ---------------------- |
+| `-node`           | Node type to back up (`all`, `datanode`, or `confignode`). Default: `all`. | No                   |
+| `-targetdir`      | Target directory for backing up the IoTDB folder.                                          | **Yes**      |
+| `-targetdatadir`  | Target path for `dn_data_dirs` files. Default: `targetdir/data/datanode/data`.     | No                   |
+| `-targetwaldir`   | Target path for `dn_wal_dirs` files. Default: `targetdir/data/datanode/wal`.       | No                   |
+
+**Process Details**:
+
+1. The `-targetdir` parameter is mandatory. If missing, the tool exits with the error: `-targetdir cannot be empty. The backup folder must be specified`.
+2. Validate consistency between configuration paths (`dn_data_dirs`, `dn_wal_dirs`) and parameters (`-targetdatadir`, `-targetwaldir`):
+
+    * If `-targetdatadir` or `-targetwaldir` is a single path, it is considered consistent.
+    * If the number of source paths (from configuration) does not match the target paths, the tool exits with the error: `-targetdatadir parameter exception: the number of original paths does not match the specified paths`.
+3. Check if `-targetdatadir` paths are on the same disk as the original paths:
+
+    * **Same disk**: Attempt to create hard links. If hard links fail, copy files instead.
+    * **Different disk**: Copy files directly.
+4. Path Matching Rules
+
+* **Many-to-One**: Multiple source paths can be backed up to a single target path.
+* **One-to-One**: A single source path can be backed up to a single target path.
+* **Many-to-Many**: Multiple source paths can be backed up to multiple target paths, but the pattern must match.
+
+#### Examples
+
+| **Configuration Paths**                                                                       | **`-targetdatadir` Paths**                                                                                                                              | **Result**       |

+
+#### Path Matching Rules Summary
+
+* **Paths separated by `;` only**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * `-targetdatadir` can also use `;` to split paths, but the count must match the source paths.
+* **Paths separated by `,` only**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * `-targetdatadir` can also use `,` to split paths, but the count must match the source paths.
+* **Paths with both `;` and `,`**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * Split paths first by `;`, then by `,`. The number of paths at each level must match.
+
+> **Note**: The `dn_wal_dirs` parameter (for WAL paths) follows the same rules as `dn_data_dirs`.

+| `-node`           | Specifies the node type to back up. Options: `all`, `datanode`, or `confignode`. Default: `all`. <br>`all`: Back up both DataNode and ConfigNode. <br>`datanode`: Back up only the DataNode. <br>`confignode`: Back up only the ConfigNode. | No                   |
+
+**Process Details**:
+
+1. Check if the `_backup` folder already exists in the current IoTDB directory or paths specified in the configuration file. If it exists, the tool exits with the error: `The backup folder already exists`.
+> When the backup folder already exists, you can try the following solutions:
+> * Delete the existing _backup folder and retry the backup.
+> * Modify the backup path to avoid conflicts.
+
+2. Create hard links from the original `dn_data_dirs` paths to the corresponding `_backup` paths.
+    * Example: If `dn_data_dirs=/data/iotdb/data/datanode/data`, the backup data will be stored in `/data/iotdb/data/datanode/data_backup`.
+3. Copy other files from the IoTDB directory (e.g., `/data/iotdb`) to the `_backup` path (e.g., `/data/iotdb_backup`).
+
+
+### 2.2 Mode 2: Manual Backup Path Mode
+
+#### Usage
+
+```bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx  
+```
+
+#### Parameter Descriptions
+
+| **Parameter** | **Description**                                                                    | **Required** |
+| ----------------------- | -------------------------------------------------------------------------------------------- | ---------------------- |
+| `-node`           | Node type to back up (`all`, `datanode`, or `confignode`). Default: `all`. | No                   |
+| `-targetdir`      | Target directory for backing up the IoTDB folder.                                          | **Yes**      |
+| `-targetdatadir`  | Target path for `dn_data_dirs` files. Default: `targetdir/data/datanode/data`.     | No                   |
+| `-targetwaldir`   | Target path for `dn_wal_dirs` files. Default: `targetdir/data/datanode/wal`.       | No                   |
+
+**Process Details**:
+
+1. The `-targetdir` parameter is mandatory. If missing, the tool exits with the error: `-targetdir cannot be empty. The backup folder must be specified`.
+2. Validate consistency between configuration paths (`dn_data_dirs`, `dn_wal_dirs`) and parameters (`-targetdatadir`, `-targetwaldir`):
+
+    * If `-targetdatadir` or `-targetwaldir` is a single path, it is considered consistent.
+    * If the number of source paths (from configuration) does not match the target paths, the tool exits with the error: `-targetdatadir parameter exception: the number of original paths does not match the specified paths`.
+3. Check if `-targetdatadir` paths are on the same disk as the original paths:
+
+    * **Same disk**: Attempt to create hard links. If hard links fail, copy files instead.
+    * **Different disk**: Copy files directly.
+4. Path Matching Rules
+
+* **Many-to-One**: Multiple source paths can be backed up to a single target path.
+* **One-to-One**: A single source path can be backed up to a single target path.
+* **Many-to-Many**: Multiple source paths can be backed up to multiple target paths, but the pattern must match.

+# Backup Tool
+
+## 1. Overview
+
+The IoTDB Full Backup Tool is designed to create a full backup of a single IoTDB node’s data via hard links to a specified local directory. The backup can then be directly started and joined to the original cluster. The tool offers two modes: **Quick Mirror Mode** and **Manual Backup Path Mode**.
+
+> **Notes**:
+>
+> * **Stop the IoTDB service before starting the backup**.
+> * The script runs in the background by default, and logs are saved to log files during execution.
+> * **IoTDB version requirement**: Must be **v1.3.2 or higher**.
+
+
+## 2. Backup Modes
+
+### 2.1 Mode 1: Quick Mirror Mode
+
+#### Usage
+
+```bash
+backup.sh/backup.bat -quick -node xxx 
+# Optional values for xxx are shown in the following examples
+
+backup.sh/backup.bat -quick -node 
+# Back up all nodes to the default path 
+
+backup.sh/backup.bat -quick -node all 
+# Back up all nodes to the default path 
+
+backup.sh/backup.bat -quick -node confignode 
+# Back up only the ConfigNode to the default path 
+
+backup.sh/backup.bat -quick -node datanode 
+# Back up only the DataNode to the default path
+```

+#### Parameter Descriptions
+
+| **Parameter** | **Description**                                                                                                                                                                                                                             | **Required** |
+| ----------------------- |---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| ---------------------- |
+| `-quick`          | Enables Quick Mirror Mode.                                                                                                                                                                                                                  | No                   |
+| `-node`           | Specifies the node type to back up. Options: `all`, `datanode`, or `confignode`. Default: `all`. <br>`all`: Back up both DataNode and ConfigNode. <br>`datanode`: Back up only the DataNode. <br>`confignode`: Back up only the ConfigNode. | No                   |
+
+**Process Details**:
+
+1. Check if the `_backup` folder already exists in the current IoTDB directory or paths specified in the configuration file. If it exists, the tool exits with the error: `The backup folder already exists`.
+> When the backup folder already exists, you can try the following solutions:
+> * Delete the existing _backup folder and retry the backup.
+> * Modify the backup path to avoid conflicts.
+
+2. Create hard links from the original `dn_data_dirs` paths to the corresponding `_backup` paths.
+    * Example: If `dn_data_dirs=/data/iotdb/data/datanode/data`, the backup data will be stored in `/data/iotdb/data/datanode/data_backup`.
+3. Copy other files from the IoTDB directory (e.g., `/data/iotdb`) to the `_backup` path (e.g., `/data/iotdb_backup`).
+
+
+### 2.2 Mode 2: Manual Backup Path Mode
+
+#### Usage
+
+```bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx  
+```
+
+#### Parameter Descriptions
+
+| **Parameter** | **Description**                                                                    | **Required** |
+| ----------------------- | -------------------------------------------------------------------------------------------- | ---------------------- |
+| `-node`           | Node type to back up (`all`, `datanode`, or `confignode`). Default: `all`. | No                   |
+| `-targetdir`      | Target directory for backing up the IoTDB folder.                                          | **Yes**      |
+| `-targetdatadir`  | Target path for `dn_data_dirs` files. Default: `targetdir/data/datanode/data`.     | No                   |
+| `-targetwaldir`   | Target path for `dn_wal_dirs` files. Default: `targetdir/data/datanode/wal`.       | No                   |
+
+**Process Details**:
+
+1. The `-targetdir` parameter is mandatory. If missing, the tool exits with the error: `-targetdir cannot be empty. The backup folder must be specified`.
+2. Validate consistency between configuration paths (`dn_data_dirs`, `dn_wal_dirs`) and parameters (`-targetdatadir`, `-targetwaldir`):
+
+    * If `-targetdatadir` or `-targetwaldir` is a single path, it is considered consistent.
+    * If the number of source paths (from configuration) does not match the target paths, the tool exits with the error: `-targetdatadir parameter exception: the number of original paths does not match the specified paths`.
+3. Check if `-targetdatadir` paths are on the same disk as the original paths:
+
+    * **Same disk**: Attempt to create hard links. If hard links fail, copy files instead.
+    * **Different disk**: Copy files directly.
+4. Path Matching Rules
+
+* **Many-to-One**: Multiple source paths can be backed up to a single target path.
+* **One-to-One**: A single source path can be backed up to a single target path.
+* **Many-to-Many**: Multiple source paths can be backed up to multiple target paths, but the pattern must match.
+
+#### Examples
+
+| **Configuration Paths**                                                                       | **`-targetdatadir` Paths**                                                                                                                              | **Result**       |

+
+#### Path Matching Rules Summary
+
+* **Paths separated by `;` only**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * `-targetdatadir` can also use `;` to split paths, but the count must match the source paths.
+* **Paths separated by `,` only**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * `-targetdatadir` can also use `,` to split paths, but the count must match the source paths.
+* **Paths with both `;` and `,`**:
+    * `-targetdatadir` can be a single path (no `;` or `,`).
+    * Split paths first by `;`, then by `,`. The number of paths at each level must match.
+
+> **Note**: The `dn_wal_dirs` parameter (for WAL paths) follows the same rules as `dn_data_dirs`.

+# 全量备份工具
+
+## 1. 概述
+
+IoTDB 全量备份工具，用于将 IoTDB 单个节点的数据通过硬链接的方式备份到本地指定地址，并可以直接启动加入原集群。备份工具提供了两种模式：快速镜像模式和手动指定备份路径模式。
+
+> 注意：
+>
+> * 备份前请停止IoTDB服务。
+> * 脚本默认后台执行，执行过程中打印的相关信息会输出到日志文件中。 
+
+## 2. 备份模式
+
+### 2.1 模式一：快速镜像模式
+
+#### 使用方法
+
+```Bash
+backup.sh/backup.bat -quick -node xxx  
+ # xxx可选值见如下示例
+
+backup.sh/backup.bat -quick -node 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node all 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node confignode 
+# 仅备份confignode节点到默认路径
+
+backup.sh/backup.bat -quick -node datanode 
+# 仅备份datanode节点到默认路径
+```
+
+#### 参数说明
+
+| **参数** | **说明**                                                                                                                                                        | **是否必填** |
+| ---------------- |---------------------------------------------------------------------------------------------------------------------------------------------------------------| -------------------- |
+| `-quick`   | 快速镜像                                                                                                                                                          | 非必填             |
+| `-node`    | 备份节点类型，可选项包括`all`/`datanode`/`confignode`，空值默认为`all`。 <br> `all`：备份`datanode`和`confignode`节点 <br>`datanode`：只备份`datanode`节点 <br> `confignode`：只备份`confignode`节点 | 非必填             |
+
+说明:
+
+1. 校验当前 `IoTDB` 文件夹及根据配置文件列出所有配置路径是否已经存在`_backup`文件夹，如果存在则退出，信息为 `The backup folder already exists`（备份文件夹已经存在）。
+> 当备份文件夹已存在时，可以尝试通过如下方式解决：
+> * 删除已有的 _backup 文件夹后重新执行备份。
+> * 修改备份路径避免冲突。
+
+2. 给原 `dn_data_dirs` 配置路径新建硬连接到对应的 `_backup` 路径 例如：`dn_data_dirs=/data/iotdb/data/datanode/data` 则备份完后数据在 `/data/iotdb/data/datanode/data_backup`
+3. 拷贝出`dn_data_dirs` 其他文件到原 `IoTDB`文件夹到对应的 `_backup` 路径中 例如：`/data/iotdb `备份后 `/data/iotdb_backup`
+
+### 2.2 模式二：手动指定模式
+
+#### 使用方法
+
+```Bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx
+```
+
+#### 参数说明
+| **参数**       | **说明**                                                                           | **是否必填** |
+| ---------------------- | ------------------------------------------------------------------------------------------ | -------------------- |
+| `-node`          | 备份节点类型`all`/`datanode`/`confignode`默认值`all`                     | 非必填             |
+| `-targetdir`     | `IoTDB`要备份到的文件夹                                                              | 必填               |
+| `-targetdatadir` | 配置项`dn_data_dirs`路径下文件要备份到的路径，默认`targetdir/data/datanode/data` | 非必填             |
+| `-targetwaldir`  | 配置项`dn_wal_dirs`路径下文件要备份到的路径,默认`targetdir/data/datanode/wal`    | 非必填             |
+
+
+说明:
+
+1. 校验参数 `-targetdir` 为必填项 ，如果参数不存在，则输出 `-targetdir cannot be empty， The backup folder must be specified`（`-targetdir` 参数不能为空，必须指定备份文件夹路径）。
+2. 对比配置文件中`dn_data_dirs`，`dn_wal_dirs` 配置路径模式和参数 `-targetdatadir`，`-targetwaldir`是否一致，如果`-targetdatadir`， `-targetwaldir`参数为单一路径则认为一致，如果不一致，输出` -targetdatadir parameter exception, the number of original paths does not match the number of specified paths`（`-targetdatadir` 参数异常，原本路径个数跟现在指定路径个数不一致）。
+3. 校验 `-targetdatadir` 配置的路径是否和原配置路径在同一块盘，如果不是同一块盘，则拷贝 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录。如果是同一块盘，则优先打硬连接 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录，如果打硬连接失败就拷贝文件到`-targetdatadir` 对应目录
+4. 配置文件路径与目标路径匹配规则
+
+* **多对一**：多个源路径可以备份到一个目标路径。
+* **一对一**：一个源路径可以备份到一个目标路径。
+* **多对多**：多个源路径可以备份到多个目标路径，但需要模式匹配。
+
+#### 示例
+
+| **配置文件路径**                                  | **参数 `-targetdatadir` 路径**           | **校验结果**            |

+#### 匹配规则总结
+
+* 当 `dn_data_dirs` 仅有 `;` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以按照 `;` 分割多个路径，但数量必须和 `dn_data_dirs` 中的路径数量相等，且路径中不能有 `,`。
+* 当 `dn_data_dirs` 仅有 `,` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以按照 `,` 分割多个路径，但数量必须和 `dn_data_dirs` 中的路径数量相等，且路径中不能有 `;`。
+* 当 `dn_data_dirs` 同时有 `;` 和 `,` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以优先按照 `;` 分割多个路径，数量必须和 `dn_data_dirs` 中的路径数量相等。每个 `;` 分割的路径中可以只输入一个路径，也可以按照 `,` 分割多个路径，但`,`分割的路径数量必须相等。
+
+> `wal` 路径通常通过 `dn_wal_dirs` 参数指定，规则同上

+# 全量备份工具
+
+## 1. 概述
+
+IoTDB 全量备份工具，用于将 IoTDB 单个节点的数据通过硬链接的方式备份到本地指定地址，并可以直接启动加入原集群。备份工具提供了两种模式：快速镜像模式和手动指定备份路径模式。
+
+> 注意：
+>
+> * 备份前请停止IoTDB服务。
+> * 脚本默认后台执行，执行过程中打印的相关信息会输出到日志文件中。
+> * IoTDB版本要求：不能低于v1.3.2
+
+## 2. 备份模式
+
+### 2.1 模式一：快速镜像模式
+
+#### 使用方法
+
+```Bash
+backup.sh/backup.bat -quick -node xxx  
+ # xxx可选值见如下示例
+
+backup.sh/backup.bat -quick -node 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node all 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node confignode 
+# 仅备份confignode节点到默认路径
+
+backup.sh/backup.bat -quick -node datanode 
+# 仅备份datanode节点到默认路径
+```
+
+#### 参数说明
+
+| **参数** | **说明**                                                                                                                                                        | **是否必填** |
+| ---------------- |---------------------------------------------------------------------------------------------------------------------------------------------------------------| -------------------- |
+| `-quick`   | 快速镜像                                                                                                                                                          | 非必填             |
+| `-node`    | 备份节点类型，可选项包括`all`/`datanode`/`confignode`，空值默认为`all`。 <br> `all`：备份`datanode`和`confignode`节点 <br>`datanode`：只备份`datanode`节点 <br> `confignode`：只备份`confignode`节点 | 非必填             |
+
+说明:
+
+1. 校验当前 `IoTDB` 文件夹及根据配置文件列出所有配置路径是否已经存在`_backup`文件夹，如果存在则退出，信息为 `The backup folder already exists`（备份文件夹已经存在）。
+> 当备份文件夹已存在时，可以尝试通过如下方式解决：
+> * 删除已有的 _backup 文件夹后重新执行备份。
+> * 修改备份路径避免冲突。
+
+2. 给原 `dn_data_dirs` 配置路径新建硬连接到对应的 `_backup` 路径 例如：`dn_data_dirs=/data/iotdb/data/datanode/data` 则备份完后数据在 `/data/iotdb/data/datanode/data_backup`
+3. 拷贝出`dn_data_dirs` 其他文件到原 `IoTDB`文件夹到对应的 `_backup` 路径中 例如：`/data/iotdb `备份后 `/data/iotdb_backup`
+
+### 2.2 模式二：手动指定模式
+
+#### 使用方法
+
+```Bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx
+```
+
+#### 参数说明
+| **参数**       | **说明**                                                                           | **是否必填** |
+| ---------------------- | ------------------------------------------------------------------------------------------ | -------------------- |
+| `-node`          | 备份节点类型`all`/`datanode`/`confignode`默认值`all`                     | 非必填             |
+| `-targetdir`     | `IoTDB`要备份到的文件夹                                                              | 必填               |
+| `-targetdatadir` | 配置项`dn_data_dirs`路径下文件要备份到的路径，默认`targetdir/data/datanode/data` | 非必填             |
+| `-targetwaldir`  | 配置项`dn_wal_dirs`路径下文件要备份到的路径,默认`targetdir/data/datanode/wal`    | 非必填             |
+
+
+说明:
+
+1. 校验参数 `-targetdir` 为必填项 ，如果参数不存在，则输出 `-targetdir cannot be empty， The backup folder must be specified`（`-targetdir` 参数不能为空，必须指定备份文件夹路径）。
+2. 对比配置文件中`dn_data_dirs`，`dn_wal_dirs` 配置路径模式和参数 `-targetdatadir`，`-targetwaldir`是否一致，如果`-targetdatadir`， `-targetwaldir`参数为单一路径则认为一致，如果不一致，输出` -targetdatadir parameter exception, the number of original paths does not match the number of specified paths`（`-targetdatadir` 参数异常，原本路径个数跟现在指定路径个数不一致）。
+3. 校验 `-targetdatadir` 配置的路径是否和原配置路径在同一块盘，如果不是同一块盘，则拷贝 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录。如果是同一块盘，则优先打硬连接 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录，如果打硬连接失败就拷贝文件到`-targetdatadir` 对应目录
+4. 配置文件路径与目标路径匹配规则
+
+* **多对一**：多个源路径可以备份到一个目标路径。
+* **一对一**：一个源路径可以备份到一个目标路径。
+* **多对多**：多个源路径可以备份到多个目标路径，但需要模式匹配。
+
+#### 示例
+
+| **配置文件路径**                                  | **参数 `-targetdatadir` 路径**           | **校验结果**            |

+
+#### 匹配规则总结
+
+* 当 `dn_data_dirs` 仅有 `;` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以按照 `;` 分割多个路径，但数量必须和 `dn_data_dirs` 中的路径数量相等，且路径中不能有 `,`。
+* 当 `dn_data_dirs` 仅有 `,` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以按照 `,` 分割多个路径，但数量必须和 `dn_data_dirs` 中的路径数量相等，且路径中不能有 `;`。
+* 当 `dn_data_dirs` 同时有 `;` 和 `,` 分割时：
+  **规则**：* `-targetdatadir` 可以只输入一个路径（路径中没有 `;` 和 `,`）。
+    * `-targetdatadir` 也可以优先按照 `;` 分割多个路径，数量必须和 `dn_data_dirs` 中的路径数量相等。每个 `;` 分割的路径中可以只输入一个路径，也可以按照 `,` 分割多个路径，但`,`分割的路径数量必须相等。
+
+> `wal` 路径通常通过 `dn_wal_dirs` 参数指定，规则同上

+# 全量备份工具
+
+## 1. 概述
+
+IoTDB 全量备份工具，用于将 IoTDB 单个节点的数据通过硬链接的方式备份到本地指定地址，并可以直接启动加入原集群。备份工具提供了两种模式：快速镜像模式和手动指定备份路径模式。
+
+> 注意：
+>
+> * 备份前请停止IoTDB服务。
+> * 脚本默认后台执行，执行过程中打印的相关信息会输出到日志文件中。 
+
+## 2. 备份模式
+
+### 2.1 模式一：快速镜像模式
+
+#### 使用方法
+
+```Bash
+backup.sh/backup.bat -quick -node xxx  
+ # xxx可选值见如下示例
+
+backup.sh/backup.bat -quick -node 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node all 
+# 备份所有节点到默认路径 
+
+backup.sh/backup.bat -quick -node confignode 
+# 仅备份confignode节点到默认路径
+
+backup.sh/backup.bat -quick -node datanode 
+# 仅备份datanode节点到默认路径
+```
+
+#### 参数说明
+
+| **参数** | **说明**                                                                                                                                                        | **是否必填** |
+| ---------------- |---------------------------------------------------------------------------------------------------------------------------------------------------------------| -------------------- |
+| `-quick`   | 快速镜像                                                                                                                                                          | 非必填             |
+| `-node`    | 备份节点类型，可选项包括`all`/`datanode`/`confignode`，空值默认为`all`。 <br> `all`：备份`datanode`和`confignode`节点 <br>`datanode`：只备份`datanode`节点 <br> `confignode`：只备份`confignode`节点 | 非必填             |
+
+说明:
+
+1. 校验当前 `IoTDB` 文件夹及根据配置文件列出所有配置路径是否已经存在`_backup`文件夹，如果存在则退出，信息为 `The backup folder already exists`（备份文件夹已经存在）。
+> 当备份文件夹已存在时，可以尝试通过如下方式解决：
+> * 删除已有的 _backup 文件夹后重新执行备份。
+> * 修改备份路径避免冲突。
+
+2. 给原 `dn_data_dirs` 配置路径新建硬连接到对应的 `_backup` 路径 例如：`dn_data_dirs=/data/iotdb/data/datanode/data` 则备份完后数据在 `/data/iotdb/data/datanode/data_backup`
+3. 拷贝出`dn_data_dirs` 其他文件到原 `IoTDB`文件夹到对应的 `_backup` 路径中 例如：`/data/iotdb `备份后 `/data/iotdb_backup`
+
+### 2.2 模式二：手动指定模式
+
+#### 使用方法
+
+```Bash
+backup.sh -node xxx -targetdir xxx -targetdatadir xxx -targetwaldir xxx
+```
+
+#### 参数说明
+| **参数**       | **说明**                                                                           | **是否必填** |
+| ---------------------- | ------------------------------------------------------------------------------------------ | -------------------- |
+| `-node`          | 备份节点类型`all`/`datanode`/`confignode`默认值`all`                     | 非必填             |
+| `-targetdir`     | `IoTDB`要备份到的文件夹                                                              | 必填               |
+| `-targetdatadir` | 配置项`dn_data_dirs`路径下文件要备份到的路径，默认`targetdir/data/datanode/data` | 非必填             |
+| `-targetwaldir`  | 配置项`dn_wal_dirs`路径下文件要备份到的路径,默认`targetdir/data/datanode/wal`    | 非必填             |
+
+
+说明:
+
+1. 校验参数 `-targetdir` 为必填项 ，如果参数不存在，则输出 `-targetdir cannot be empty， The backup folder must be specified`（`-targetdir` 参数不能为空，必须指定备份文件夹路径）。
+2. 对比配置文件中`dn_data_dirs`，`dn_wal_dirs` 配置路径模式和参数 `-targetdatadir`，`-targetwaldir`是否一致，如果`-targetdatadir`， `-targetwaldir`参数为单一路径则认为一致，如果不一致，输出` -targetdatadir parameter exception, the number of original paths does not match the number of specified paths`（`-targetdatadir` 参数异常，原本路径个数跟现在指定路径个数不一致）。
+3. 校验 `-targetdatadir` 配置的路径是否和原配置路径在同一块盘，如果不是同一块盘，则拷贝 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录。如果是同一块盘，则优先打硬连接 `dn_data_dirs` 配置的文件到参数 `-targetdatadir` 对应目录，如果打硬连接失败就拷贝文件到`-targetdatadir` 对应目录
+4. 配置文件路径与目标路径匹配规则
+
+* **多对一**：多个源路径可以备份到一个目标路径。
+* **一对一**：一个源路径可以备份到一个目标路径。
+* **多对多**：多个源路径可以备份到多个目标路径，但需要模式匹配。
+
+#### 示例
+
+| **配置文件路径**                                  | **参数 `-targetdatadir` 路径**           | **校验结果**            |
