Hi Khalid

You and you're consultant are talking about the same procedure....

To backup your primary site to the second site, you'll need to use 
server-to-server virtual volumes(if you cant get a FC connection to your 
library on your secondary site). You then define a devclass and a copypool 
based on that devclass. After that, you'll just have to start the process 
of backup stgpool primarypool copypool.

I cant see any other way of backing up the two servers to eachother rather 
than using server-to-server communication. This method is also called 
"Electronic Vaulting" and is a part of TSM Disaster Recovery Manager. You 
cannot use any form of TSM backup/archive client procedure to backup the 
server data, as the client wont have access to the information stored on 
your tapes.

Best Regards

        Subject:        Server-Server DRM Configuration ...


I have a humble question regarding the benefits of Server-Server 
communication. I have two sites 60 miles apart with 45MB pipe in between, 
and each of them has a TSM server and a library. I was proposed by a TSM 
consultant to establish server-server DRM configuration to enable quick 
recovery in case of disaster. My humble proposal in response is to NOT do 
that but rather backup each site to the other location. That way the DB is 
offsite as well as the primary copy, therefore DR copy of the primary is 
NOT needed either. I would do this reciprocally for the other site. In 
case of DR, data is locally available at the other site.

Is this not a better solution than configuring server-server communication 
and send a copy of the primary pool as well as the DB tape offsite.

Please help me understand what I may be missing in my proposal, or what 
benefits I don't see in the traditional DRM using Server-Server 
configuration.

Please advise!

Thank you,

Khalid Khan
