(from the Windows Administrator's Guide, page 87) Directory-Level Backup and Restore
If you have a large NAS file system, initiating a backup on a directory level will reduce backup and restore times and provide more flexibility in configuring your NAS backups. By defining virtual file spaces, a file system backup can be partitioned among several NDMP backup operations and multiple tape drives. You can also use different backup schedules to back up sub-trees of a file system. The virtual file space name cannot be identical to any file system on the NAS node. If a file system is created on the NAS device with the same name as a virtual file system, a name conflict will occur on the Tivoli Storage Manager server when the new file space is backed up. See the Administrator's Reference for more information about virtual file space mapping commands. Note: Virtual file space mappings are only supported for NAS nodes. -- Mark Stapleton ([EMAIL PROTECTED]) Office 262.521.5627
