The following requirements must be met before installation:
| • | Administrative privileges for the user executing the client installation |
| • | For legacy Exchange agent, .NET 2.0 Framework or higher |
| • | For legacy SQL Server agent, Microsoft SQL Server Browser |
| • | Approximately 1100 MB of free space on the system drive, usually volume C:. |
(Applicable even if installing on a volume other than C:.)
| • | Single Instance Storage (SIS) on Windows Storage Server 2008 is not supported and must be disabled for the agent to properly perform backups. |
| • | To protect Exchange, SQL Server, or Hyper-V, the following VSS writers are required: |
| – | VSS Exchange Writer is required for the Exchange agent. |
| – | VSS SQL Writer is required for the SQL Server agent. |
| – | VSS Hyper-V Writer is required for the Hyper-V agent. |
Note: VSS writers are not required for Windows 2000 and NT clients as these older environments do not use Microsoft VSS technology. Backups of Exchange and SQL data in these environments use the legacy SQL and Exchange agents.
