Software Suite for Microsoft SQL Licenses User guide

NOTE: Due to an SQL instance limitation, the recommended maximum number of databases for
which you can create snapshot backups at the same time is 35.

Features Not Supported
• Microsoft SQL Server offline backup
• VSS backup types “Incremental,” “Differential,” “Copy,” and “Log”
• All backup tools, except for HP Data Protector and Symantec NetBackup
• Access to HP 3PAR Storage System via SSH
• Display of different versions of Microsoft SQL Server from the same Recovery Manager backup
server
• Interoperability between Windows Server 2003 and Windows Server 2008
In other words, you cannot mount a virtual copy created under Windows 2003 to a Windows
2008 target host.
• Taking a snapshot of the SQL servers created with the SQL Server Authentication setting.
Recovery Manager for SQL supports SQL servers created with the Windows Authentication
setting. If you are running SQL Server, Recovery Manager supports both Windows
Authentication mode and SQL Server and Windows Authentication mode.
• Taking a snapshot of a database residing on a network mapped volume
• Virtual copy ownership transferring. For example, you can only remove virtual copies if you
created them, and you can only unmount virtual copies if you mounted them.
• Taking a snapshot of an instance or database that resides on dynamic disks
• Mounting snapshots to a Windows host that resides in virtual environment
• Performing a restore in a virtualization environment
• Date customization. Recovery Manager always displays dates in month/day/year format.
• Windows automount feature
Microsoft Volume Shadow Copy Service
Microsoft includes Volume Shadow Copy Service (VSS) in Windows 2003 and Windows 2008
to simplify the enterprise’s storage environment, which provides a framework for creating a
point-in-time copy of either a single volume or multiple volumes.
Microsoft Windows Server 2008 VSS works with VSS-aware applications that are used to determine
when a volume shadow copy (snapshot) can be made. (A snapshot is a virtual copy: a copy of
some data set—for example, a disk volume—at a point in time.) Before making a snapshot, VSS
communicates with the operating system and applications to freeze computing tasks, which enables
an application-consistent snapshot to be taken. The shadow copy volume is then used for the actual
backup. After VSS saves the shadow copy volume on the backup device, it deletes the shadow
copy.
