Default BES Disaster Recovery Checklist

Please Login to Remove!

I've looked and can't find any really good information on BlackBerry Disaster Recovery. I was wondering if any of you had a "checklist" of things to do in the event of a disaster and the steps to recover from a disaster. Thanks in advance!

*note: these observations are for Exchange.

well, i honestly thought the database for BES 4.0 kept a lot of information. and while it does, you can lose the database and be just fine with simply creating a new database from scratch.

so my opinion on what is perhaps the most needed things for backup are a) the service account mailbox, and b) a list of all users. if you lose the database, or if you simply need to drop it and create a new one, you won't have any issues with lost data that is important. you will need to readd the users back to the BES and click the option to keep their information (i believe it asks if you want to clear statistics) - this will poll the information (PIN, etc) from the Exchange mailbox and the users will be working again within seconds. i *believe* you would have to set their options in this situation, but thats a minor inconvenience compared to total loss.

however, best practices for the database are to have either a database (MSDE 2000 or SQL 2000) that is copied to a standby server (every night) or a real-time database synchronization (active-passive, which will only require 1 SQL 2000 license) between the primary and standby servers - these databases can either be local to the server or in a clustered SQL environment (if you have one). and while we're on the subject on the subject, it is recommended to have a passive standby server with the BES services turned down, in the event of a hardware/software failure on the primary server.

as far as HA or DR is concerned with the BES, there's not much work to restoring a server, and it will be highly unlikely that you will suffer too much of a loss in the event of a server crash (worst case, you will have a few hours downtime). the big loss would come in the event of corruption or some sort of failure with the service account mailbox, in my opinion (this goes for 3.6 and 4.0).
