SQL Server Stretch Database

Stretch Database

Data can be split between on-premises and cloud storage. 

With Stretch Database, cold/audit data is kept in the cloud and data remains available for users to

query, might be a small amount of additional latency associated with queries. Data in the cloud is backed up automatically. 

With Stretch Database, active data is kept on-premises for maximum performance and reduce storage requirements both for data and backups (it run quicker than standard backups). 

It requires no changes to new or existing TSQL queries.
