[编辑](https://github.com/oceanbase/oceanbase-doc/edit/V4.5.0/zh-CN/700.reference/1500.Components-and-Tools/100.manage/200.ob-admin/400.backup-and-recovery/600.dump-backup.md)  

dump_backup 功能是 ob_admin 的一个子功能，可解析用于物理备份的数据备份内容。本文主要介绍 dump_backup 的几种用法。

## help 命令

您可使用该命令输出 dump_backup 的使用方法。

```shell
./ob_admin dump_backup --help

```

输出为：

```shell
Usage: dump_backup command [command args] [options]
commands:
        -h,--help                     display this message.
options:
        -d,--backup-file-path         absolute backup file path with file prefix
        -s,--storage-info             oss/cos should provide storage info
        -f,--file-path                relative data file path
        -o,--offset                   data offset
        -l,--length                   data length
        -c,--check-exist              check file is exist or not
samples:
  dump meta:
        ob_admin dump_backup -dfile:///home/admin/backup_info
  dump macro:
        ob_admin dump_backup -dfile:///home/admin/macro_block_1.0 -o1024 -l2048
  dump data with -f:
        ob_admin dump_backup -f/home/admin/macro_block_1.0 -o1024 -l2048
  dump data with -s:
        ob_admin dump_backup -d'oss://home/admin/backup_info' -s'host=xxx.com&access_id=111&access_key=222'

```

选项说明如下：

| 选项名 | 是否必选 | 数据类型 | 默认值 | 说明 |
| --- | --- | --- | --- | --- |
| -d/--backup-file-path | 是 | 字符串 | 无 | 指定数据备份文件的绝对路径。 |
| -s/--storage-info | 否 | 字符串 | 无 | 指定对象存储的 Host 地址和验证信息。验证信息包含访问 ID（access_id）和访问密钥（access_key），对于 Amazon S3 服务，还需明确指定区域（s3_region）。 |
| -f/--file-path | 否 | 字符串 | 无 | 指定数据备份文件的相对路径。   #### 注意    该选项已废弃，请勿配置。 |
| -o/--offset | 否 | 整型 | 0 | 设置读取偏移量，根据指定的数据备份文件不同有如下两种情况：   - 当指定的数据备份为宏块文件时，表示读取的宏块字节偏移量。 - 当指定的数据备份为 table_list 文件时，表示读取的 table_list 条目偏移量。当 `-o`/`--offset` 配置的值大于 table_list 总数时，输出为空。 |
| -l/--length | 否 | 整型 | 0 | 设置读取长度，根据指定的数据备份文件不同有如下两种情况：   - 当指定的数据备份为宏块文件时，表示读取的宏块字节数。 - 当指定的数据备份为 table_list 文件时，表示读取的 table_list 条目数。当读取偏移量（offset）与读取长度（length）的和大于 table_list 总数（下文示例输出中的 `count`）时，输出范围为 [offset,count)。 |
| -c/--check-exist | 否 | 布尔型 | false | 控制是否检查数据备份文件是否存在。指定该选项时，命令将检查输入的数据备份文件是否存在，若文件存在将打印 `true`，反之则打印 `false`。 |

## 使用示例

### 查看当前租户的全量备份信息

```shell
./ob_admin dump_backup -d'file:///home/admin/backup/ob_backup_oracle_tenant/data/backup_set_1_full/tenant_backup_set_infos.obbak'

```

### 查看备份集中包含的用户表名

1. 获取 table_list 的记录总数及 batch_size

   ```shell
   $ ./ob_admin dump_backup -d'file:///home/admin/backup/ob_backup_oracle_tenant/data/backup_set_1_full/infos/table_list'

   ```

   命令输出如下：

   ```shell
   -------------------table_list--------------------—-
   |               count|100000
   |          batch_size|20000

   ```
 2. 根据输出中的 count 值，指定 `--offset` 和 `--length`

   ```shell
   $ ./ob_admin dump_backup -d'file:///home/admin/backup/ob_backup_oracle_tenant/data/backup_set_1_full/infos/table_list' --offset=1 --length=3

   ```

   上述命令表示在全量 table_list 中从第 2 条记录（offset+1）中读取，读取的记录数量为 3 条（length），输出如下：

   ```shell
   -------------------table_list--------------------—-
   |               2|{database_name:d2, table_name:t2}
   |               3|{database_name:d3, table_name:t3}
   |               4|{database_name:d4, table_name:t4}

   ```

### 查看备份集诊断信息

```shell
$ ./ob_admin dump_backup -d'file:///home/admin/backup/ob_backup_oracle_tenant/data/backup_set_1_full/infos/diagnose_info.obbak'

```

输出为：

```shell
