HP DP的问题请教

4nai

想veritas的muticopies,networker的clone,cv的辅助拷贝，DP的类似功能是什么。
即数据备份到一个备份介质同时，希望还能有一份数据保存到另外一份介质。其他软件该项更能都免费，DP免费吗？另外如果能实现数据，大概数据处理流程是怎么样？是如nbu同时备份到2份介质，还是如networker先到第一份，之后组织第一份上的写到第二份？还是其他？

可以实现

使用Copy & Consolidation, 是不是免费我不确定,   应该是的,   :wink: :wink:

我自己觉得是先写一份, 然后按照你的定义脚本再复制到另一份截至, 不过我没去做过, 不能确切回答你, 等高手

DP是免费的，叫Object mirroring
What is object mirroring?
The Data Protector object mirror functionality enables writing the same data to several
media sets simultaneously during a backup session. You can mirror all or some
backup objects to one or more additional media sets.
这个是同时做的。
DP 还有备份完一盘带，再复制到另外几盘上，叫Copying media
What is media copying?
The Data Protector media copy functionality enables you to copy media after a
backup has been performed. Media copying is a process that creates an exact copy
of a medium containing a backup. You can use it to duplicate media for archiving
or vaulting purposes. After the media have been copied, you can move either the
original media or the copies to an off-site vault.

还有基于backup session的复制，叫object copy。
以上都是免费的。

感谢！但还有一个问题，看了一些介绍，需要source和target的介质类型需要一样。但如果一个是vtl，一个是物理带库，但vtl是de-dup后的，所以可能虚拟磁带和物理磁带大小不不一样，这样会影响copy吗，如果是使用Object mirroring.

DP不会有这个限制吧，source和target的介质类型应该可以不同。

设计到VTL的话建议使用Smart media copying

cncqpansky

What is smart media copying?
In smart media copying, the data is first backed up to a virtual tape library (VTL)
configured on the Virtual Library System (VLS). Then, a copy of a virtual tape
containing a backup is made to the physical library attached to the VLS in a process
called automigration. Data Protector initiates the copy process, which is then
performed by the VLS. The data is transferred to a physical library in a smart copy
operation, which allows Data Protector to distinguish between the source and the
target media thus enabling media management. The smart copy media follow the
Data Protector format and can thus be inserted in any compatible tape drive and
read by Data Protector. The result of smart copying is two identical sets of media,
the source medium located on the VLS' virtual tape and the target medium (a smart
copy) located on a physical tape library attached to the VLS. Either of these copies
can be used for restore, thus increasing the security and availability of the backed
up data. You can also keep smart media copies for archiving or vaulting purposes.
Data Protector offers two types of smart media copying: automated smart media
copying and interactive smart media copying.

DP不会有这个限制吧，source和target的介质类型应该可以不同。

You need two devices, one for a source medium and one for a target medium. You can also copy media in library devices with multiple drives. In this case, use one drive for the source medium and another for the target medium.

The source medium and the target medium must be of the same type.

If your target media are Data Protector media with data protection, you must first recycle the media and then format them.

在线帮助是这么些的。
