Default BB and DR working hand-in-hand

Please Login to Remove!

Afternoon all!

I have a quick question, hopefully someone can help. I currently have BES 4.0.6.12 running on a single server in our HO.

We have just begun revamping our DR site and want to have a back up BES server the other side.

Does anyone know of any good walkthroughs or guides to help me along this dark path?

Rgds

ok here is what you can do

-take complete backup of your MSDE
-stage a new BES server with a different name but same BES instance , settings, MSDE and SRP
-make sure that you do not select to start BES services at the end of setup this will disable your SRP, you cannot use SRP twice
-now restore your MSDE from production server

leave the BES services setup to manual DO NOT start them

now you are done, you have a DR server, when your production server goes tits up, just restore your MSDE on the DR server and start the BES services,

or you can use the old MSDE restored on installation time, only thing in this case users will loose some email and changes made.

another solution can be image your existing BES, restore on a server that is no connected to network, and stop all BES services , connect to network rename server then send the server off to DR site, with BES services stoped

in case of DR make your call to either restore your MSDE or not and bring server online

you might want to move to a high availability SQL server and host your BES DB on it, and point both production and DR servers to same DB, in this case if your BES goes down, just bring up BES services on DR box and you are golden


Here is what we have implemented for our 560 users

Two BES servers with unique SRP
DB is hosted on a high end SQL box
both servers point to the same DB
in case of DR i can just login to surviving server and move users accross to working server

users stay on the DB, as long as you have a current backup of your DB or its hosted on a seperate box you dont need to recover users
