ProblemAs DBAs, we don't only have the responsibility to backup databases on regular basis, but also to ensure that backup drives and tapes are secure so databases can be restored when needed. I heard that SQL Server 2012 supports backups and restores using a Windows Azure Blob Storage account. How does this work and how do I get started?By: Arshad Ali

Mejores prácticas
Usar nombres únicos para identificar cada backup fecha/hora/bd/servidor
Definir el acceso al contenedor como private Utilizar la misma región para mejorar rendimiento y manejar costos (*) Monitorear constantemente el fallo/éxito de las operaciones si se
automatiza Usar la opción WITH COMPRESSION para minimizar los costos de
storage y el tiempo Usar encripción (*) Hacer pruebas de tiempo de respaldo y recuperación Revisar los SLA’s de Azure(

Tail-log backup (respaldo del log)
A tail-log backup is a transaction log backup that includes the portion of the log that has not previously been backed up (known as the active portion of the log). A tail-log backup does not truncate the log and is generally used when the data files for a database have become inaccessible but the log file is undamaged.
