+# 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`.
