Disaster recovery is simple to set up, based on where the database is. Just remember to ALWAYS backup the database no matter what. If the database is on a separate server(SQL) then use the following steps:
1. Set local BESAdmin permissions (local admin, etc.)
2. Install Exchange System Management Tools and any service packs to meet or exceed the version of Exchange Server in the environment(Exchange Environment Only)
3. Install the BES (As BESAdmin) and point it to the production database and DO NOT start the services. That will avoid the disabling of your SRP on RIM's network. Also remember to use the same BES name for both, if not you will end up with 2 different BES in the BB Manager
If the BES is using local MSDE then follow these steps:
1. Backup the production database
2. Install MSDE on the new machine
3. Move the database folder from the BES 4.1 install files to the new server and run the createdb.exe from a DOS Window to create a blank database first
4. Restore the production database over the newly created BESMgmt database
5. Install the Exchange System Management tools and appropriate service packs (Only if you're in an Exchange Environment)
6. Set the local permissions for the BESAdmin account
7. Install the BES but DO NOT start the services
Make sure to have a current backup of the production database ready in case the one on the Disaster Recovery BES is "out of date".
There should also be some documentation on RIM's
BlackBerry Technical Solution Center, just search for "disaster recovery".
Any questions about moving the database can also be found on RIM's TKC as well, look for "move database".
Hope that helps.
