Directory-level backup and restore for NDMP operations

The DEFINE VIRTUALFSMAPPING command maps a directory path of a NAS file server to a virtual file space name on the Tivoli® Storage Manager server. After a mapping is defined, you can conduct NAS operations such as BACKUP NODE and RESTORE NODE by using the virtual file space names as if they were actual NAS file spaces.

To start a backup of the directory, issue the BACKUP NODE command and specify the virtual file space name instead of a file space name. To restore the directory subtree to the original location, run the RESTORE NODE command and specify the virtual file space name.

Virtual file space definitions can also be specified as the destination in a RESTORE NODE command. In this way, you can restore backup images (either file system or directory) to a directory on any file system of the NAS device.

You can use the web client to select files for restore from a directory-level backup image because the Tivoli Storage Manager client treats the virtual file space names as NAS file spaces.
