Disaster Recovery

Data Stream as a stand alone product is not disaster tolerant but works in conjunction with industry leading products to form a disaster recovery process.
Disasters are never a planned event but planning for one is critical to minimizing impact. 
Microsoft SQL Agent
Data Stream recommends the use of Ola Hallengren Scripts.
Don't forget to set a backup schedule for each Microsft SQL Agent Job. [Reference]
Ola Hallengren Scripts
Download the scripts here.
Once you have successfully executed the Ola Hallengren Scripts, the Microsoft SQL server agent should contain the following jobs.
Load Balancing Fail-over
Manual Fail-over
When the mirrored database is synchronized, the database owner or system administrator can initiate manual fail-over to the secondary server.
USE master;
GO
​
ALTER DATABASE [DataStream] SET PARTNER FAILOVER;
Validation of mirroring status is critical to a successful fail-over. [Reference]
Automatic Fail-over
Automatic fail-over occurs when the fast startup is disabled and computer is properly shutdown.
Automatic fail-over will not occur in a loss of power disaster.
