VSS Options
Use the VSS Options property page to configure preferences that are used during VSS backup and restore operations.
- Default Backup Destination
- Select the default storage location for your backups. Tip: You must have the Tivoli® Storage FlashCopy® Manager license to use the Tivoli Storage Manager software. If you have only the Data Protection license, only the Tivoli Storage Manager option is enabled.You can select from the following storage locations:
- TSM
- The backup is only stored on Tivoli Storage Manager server storage. For SQL Server, Tivoli Storage Manager server is the default backup destination.
- Local
- The backup is only stored on local disk.
- Both
- The backup is stored on both Tivoli Storage Manager server storage and local disk.
For Tivoli Storage Manager configurations, the backups can be stored on a local disk, but managed on the Tivoli Storage Manager server. The Tivoli Storage Manager server maintains the metadata or information about where the local snapshot is stored.
- Local DSMAGENT Node name
- Specify the node name for the DSM Agent node of the local client system that creates the VSS backups.
- Remote DSMAGENT Node name
- Specify the node name of the system that moves the VSS data to Tivoli Storage Manager server storage during offloaded backups. If you do not use offloaded backups, you can leave this field blank.
- Import VSS snapshots only when needed
- By default, local persistent VSS snapshots are automatically imported to the Windows system where the snapshots are created. If you select this option,
the VSS snapshots are imported to the local host when needed to perform FlashCopy Manager operations.
To automatically import local persistent snapshots to the Windows system where the snapshots are created, the check box should be cleared.
If you intend to keep many backup versions (for example, more than 100 backup versions), or, if there is a limit to the number of LUNs that your server can use (for example, in virtual machine environments), select this option.
When you select this option, if the VSS hardware provider does not support transportable snapshots, or, if no hardware provider is available, the backup is completed, but the VSS snapshot is imported and is not transportable.
If you are running in a VMware environment and want to use VMware vMotion, ensure the LUNs are properly zoned to the ESX hosts and select this option. By choosing to import VSS snapshots when the snapshots are needed, the import process maps the VSS snapshot to the ESX host where the Windows virtual machine is running.
