简介
本文档介绍如何将数据库(DB)从一台思科M系列设备备份到另一台。
先决条件

Cisco 建议您了解以下主题：
问题
开始将数据库备份到辅助M系列设备。
解决方案
以下是开始将数据库备份到辅助M系列设备之前的要求。
- 两个M系列设备必须位于同一AsyncOS版本（仅7.2及更高版本）
- 目标M系列设备必须有足够的磁盘空间用于备份。导航至系统管理>磁盘管理（请参阅有关如何在剩余磁盘时分配的联机文档）。
如果在设置期间磁盘空间不足，可能会收到类似以下消息：
Verifying target machine for version compatibility and disk space...
Backup cannot be scheduled. Reason: There is not enough space for Centralized
Spam Quarantine, Centralized Email Tracking, Centralized Reporting. Please
increase disk allocation for these services on the target machine.
或者
Verifying target machine for version compatibility and disk space...
Backup cannot be scheduled. Reason: There is not enough space for Centralized
Web Tracking. Please increase disk allocation for these services on the target
machine.
检查目标计算机上前面提到的磁盘配额。
两个安全管理设备(SMA)、一个M650(名为m650sma.run的数据库系统源)和目标M1050(名为m1050sma.run的数据库系统的目标备份和IP 192.168.15.1)。
登录源M系列（在我们的test sma1.example.com中）上的CLI并输入以下命令：
