支持备份到raw device。

可以到这里下载NetWorker 7.6 SP3 Administration Guide.pdf:

https://community.emc.com/thread/162551?tstart=0

第94和95页有介绍Considerations for backing up raw partitions。

~~~~~~~~~~~~~~~~~~~~~

Considerations for backing up raw partitions

The NetWorker software must have exclusive access to a file system to perform a raw

backup. Close as many applications as possible before doing a raw disk backup. If the

raw partition contains data managed by an active database management system

(DBMS), ensure that the partition is offline and the database manager is shutdown.

For greater flexibility when backing up partitions that contain DBMS data, use a

NetWorker Module application.

Backing up raw partitions on UNIX

To back up raw disk partitions on UNIX, use the rawasm directive. “Precautions

when using rawasm to back up UNIX raw partitions” on page 180 provides more

information.

Backing up raw partitions on Windows

To back up a raw disk partition on Windows, specify the raw disk partition in a save

set. Identify the raw partition as a physical drive or as a logical drive. For example:

save -s NetWorker_server_name \\.\PhysicalDrive0

save -s NetWorker_server_name \\.\C:

先看下你裸设备上面跑的是什么应用?可以通过应用模块备份。

裸设备上是DB2

手册中写到如下内容

rawasm.png

那么如何配置呢?

是不是创建DB2客户端,在save set里面加上rawasm:/dev/oracle1(假设我的裸设备是/dev/oracle1)?

应该不是。

NetWorker 7.6 SP3 Administration Guide.pdf下面这几段话来看,rawasm只是用于备份非数据库数据到裸设备。备份数据库数据到裸设备,要用NetWorker Module。你仙子已经使用NMDA Module来备份DB2数据库了,应该就不需要用rawasm了。按照EMC NetWorker Module for Databases and Applications (NMDA) 1.2 Administration Guide73页上的说明,DB2 clientsave set应该写为DB2:/database_name/node_name

DB2 Module的具体配置方法,建议你仔细看下EMC NetWorker Module for Databases and Applications (NMDA) 1.2 Administration Guide。

One can specify the rawasm directive to back up raw disk partitions on UNIX. However, if the raw partition contains data managed by an active database management system (DBMS), ensure that the partition is offline and the database manager is shutdown. For greater flexibility when backing up partitions that contain data managed by a DBMS, use a NetWorker Module application.

Similarly, if rawasm is used to save a partition containing a UNIX file system, the file system must be unmounted or mounted read-only to obtain a consistent backup.

是不是说DB2数据如果存放在裸设备上,我用NMDA备DB2数据库就行了?

我觉得应该是这样。如果用NMDA备份DB2数据到裸设备,应该不需要特别的设置。至少在NMDA Administration Guide里我没有找到有写需要做特别的设置。
