Executive Summary
Microsoft SQL Server with nearly 15% market share is one of the widely deployed relational
database systems.
SQL Server implementations have become more complex and require more reliability than before.
Database service-level agreements (SLAs) require predictable performance, and outages are
disruptive and costly for database consumers. SQL Server databases are growing significantly larger
to meet the needs of today's organizations, while business requirements dictate shorter backup and
restore windows.
Meeting the recovery point objective (RPO) - the maximum acceptable level of data loss following an
unplanned “event” and recovery time objectives (RTO) - a period of time within which business and /
or technology capabilities must be restored, is critical. Application consistent backup tools &
capabilities help in meeting these objectives.
Vital Labs team has built application consistent backup and recovery tools for Microsoft applications
such as SQL Server, Exchange and SharePoint. This case study focuses on backup & Recovery product
for SQL Server.
The customer for this product was a mid size Storage vendor, based in the bay area, USA. The end
users are several enterprises and managed services providers who are actively using these products
built by us.

Implementation approach
Recovery Manager for SQL Server (RMSQL) is a Windows host-based application that manages
consistent backups and recovery of Microsoft SQL Server databases. Objective of RMSQL is to
achieve capabilities of Storage array such as backup, restore, and clone etc at SQL Server database
level operations.
Recovery Manager for SQL uses Microsoft VSS Framework to create rapid application consistent
backups. This technology interfaces with the storage snapshot technology and processes. RMSQL will
place SQL database in to frozen state while performing backup. RMSQL will interact with VSS
framework to perform database level backup and internally VSS framework place the call to VSS
writer (SQL Writer) to freeze database. Then framework interacts with VSS Hardware Provider
(Storage Hardware Provider) to create volume snapshot on Storage through REST API’s. Once
Storage snapshot copy has been created, RMSQL notifies Microsoft VSS that backup is complete and
freeze will be released. RMSQL notifies Microsoft SQL Server that full backup has been created.
