Database security – Failover and Disaster Recovery

OverviewFailover is the process of maintaining uptime for your database. It can be automatic or manually triggered. The enterprise must calculate how much downtime it can tolerate and plan to have less than that. This is sometimes called high availability. The enterprise must also plan for how to handle the loss of a database server. How does it recover? How quickly? What are the sources of failure? How much complexity can your enterprise manage? Will you rely on backup, mirroring, or clustering? Will you use an internal database solution or a third party application?

Reply to two classmates’ posting in a paragraph of at least five sentences by asking questions, reflecting on your own experience, challenging assumptions, pointing out something new you learned, offering suggestions. These peer responses are not ‘attaboys’.  
It is important that you use your own words, that you cite your sources, that you comply with the instructions regarding length of your post and that you reply to two classmates in a substantive way (not ‘nice post’ or the like).  Your goal is to help your colleagues write better. Do not use spinbot or other word replacement software. It usually results in nonsense and is not a good way to learn anything. . I will not spend a lot of my time trying to decipher nonsense. Proof read your work or have it edited. Find something interesting and/or relevant to your work to write about.  Please do not submit attachments unless requested.
