Required node names for basic VSS offloaded backups
VSS offloaded backups require specific node name settings.
| Proxy node type | Node name | Where to specify |
|---|---|---|
| Target node | IBM Storage Protect Snapshot for Microsoft Exchange ServerIBM Storage Protect Snapshot for Microsoft SQL Server node name | Use the nodename option in the IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server options file (dsm.opt) |
| Agent node | Local DSMAGENT Node | Use the localdsmagentnode parameter in the IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server configuration file (tdpexc.cfg) or (tdpsql.cfg) |
| Agent node | Remote DSMAGENT Node | Use the remotedsmagentnode parameter in the IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server configuration file tdpexc.cfg) or (tdpsql.cfg) |
- Target node
- This node name is where IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server is installed. This node name (specified with the nodename option in the dsm.opt file) is referred to as the IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server node name.
- Agent node - Local DSMAGENT Node
- This node name is where the
backup-archive client and VSS provider are installed. This node is responsible for processing the
VSS operations because IBM Storage Protect Snapshot for Microsoft Exchange Server does not process
any direct VSS operations.
This node name is referred to as the Local DSMAGENT Node and is specified with the localdsmagentnode parameter in the IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft SQL Server configuration file ((tdpexc.cfg) or or (tdpsql.cfg) by default). To specify this parameter with the Properties window of Microsoft Management Console (MMC), select VSS backup. In the Properties window, you can update the Local DSMAGENT Node name. Otherwise, use the tdpexcc set or tdpsqlc set command to specify this parameter.
- Agent node - Remote DSMAGENT Node
- This node name is a separate system that must also have the
backup-archive client, and the VSS provider installed. In addition, for Exchange Server workloads,
ensure that you install the same level of the Exchange System Management Tools that is installed on
your Exchange production server. This node is responsible for moving VSS snapshot data from local
shadow volumes to the IBM Storage Protect server.
This node name is referred to as the Remote DSMAGENT Node and is specified with the remotedsmagentnode parameter in the IBM Storage Protect Snapshot for Microsoft Exchange Serveror IBM Storage Protect Snapshot for Microsoft SQL Server configuration file (tdpexc.cfg or tdpsql.cfg by default). To specify this parameter with the Properties window of MMC, select VSS backup. Then, you can update the Remote DSMAGENT Node name. Otherwise, use the tdpexcc set or tdpsqlc set command to specify this parameter.
The choice of available systems depends on whether the systems have access to the local shadow volumes that contain the VSS snapshot backups. This node name is only valid for VSS environments that support shadow copies that can be transported.
If you are using the default VSS system provider, you cannot specify the node name.
