(SQL) Tip of the Day: Business continuity during a SQL Azure Outage
Today’s (SQL) Tip…
We have two options during an outage Geo-Replication and Geo-Restore.
If the database has geo-replication, failover to the geo-secondary (https://msdn.microsoft.com/en-us/library/azure/hh852669.aspx). There is a risk of data loss during failover, which is documented in the link. Expected data loss is <2s of transactions.
Perform a geo-restore to another region (https://msdn.microsoft.com/en-us/library/azure/hh852669.aspx), with up to 5 minutes of data loss.
After this you will most likely need to change your application connection string.
