Prerequisites

Before configuring the application backup, ensure that the requirements listed below are met.

To check the VSS writers state, use the vssadmin list writers command.

Common requirements

For Microsoft SQL Server, ensure that:

• At least one Microsoft SQL Server instance is started.
• The SQL writer for VSS is turned on.

For Microsoft Exchange Server, ensure that:

• The Microsoft Exchange Information Store service is started.
• Windows PowerShell is installed. For Exchange 2010 or later, the Windows PowerShell version must be at least 2.0.
• Microsoft .NET Framework is installed.

  For Exchange 2007, the Microsoft .NET Framework version must be at least 2.0.

  For Exchange 2010 or later, the Microsoft .NET Framework version must be at least 3.5.

• The Exchange writer for VSS is turned on.

On a domain controller, ensure that:

• The Active Directory writer for VSS is turned on.

When creating a backup plan, ensure that:

• For physical machines, the Volume Shadow Copy Service (VSS) backup option is enabled.
• For virtual machines, the Volume Shadow Copy Service (VSS) for virtual machines backup option is enabled.

Additional requirements for application-aware backups

When creating a backup plan, ensure that Entire machine is selected for backup. The Sector-by-sector backup option must be disabled in a backup plan, otherwise it will be impossible to perform a recovery of application data from such backups. If the plan is executed in the Sector-by-sector mode due to an automatic switch to this mode, then recovery of application data will also be impossible.

If the application runs on a virtual machine that is backed up by Agent for VMware, ensure that:

• The virtual machine being backed up meets the requirements for application-consistent quiescing listed in the following VMware knowledge base article: https://pubs.vmware.com/vsphere-6-5/index.jsp?topic=%2Fcom.vmware.vddk.pg.doc%2FvddkBkupVadp.9.6.html
• VMware Tools is installed and up-to-date on the machine.
• User Account Control (UAC) is disabled on the machine. If you do not want to disable UAC, you must provide the credentials of a built-in domain administrator (DOMAIN\Administrator) when enabling application backup.
