IC55047: RESTORE/RETRIEVE TO ALTERNATE SYSTEM USING FROMNODE OR VIRTUALNODENAME REQUIRES DESTINATION FILESPEC
Closed as suggestion for future release.
TSM manuals do not clearly document the default behaviour when attempting to restore/retrieve to an alternate system. If no destination filespec is specified, TSM client will attempt to restore/retrieve to the original filesystem where the objects were backed up/archived from. Online help and TSM manuals should document the need for a destination filespec in sections detailing how to recover objects backed up from one system to an alternate system. In the 5.5 TSM B/A Client Installation and User's Guide: *** Restoring or retrieving files from another client node After users grant you access to their files on the server, you can restore or retrieve those files to your local system. You can display another user's file spaces on the server, restore the other user's backup versions, or retrieve the other user's archive copies to your local file system, by following these steps: Click Utilities from the main window. Click Access Another Node. The Access Another Node window appears. Type the node name of the user's host machine in the Node name fi eld. Click the Set button. If you are using commands, use the fromnode option to indicate the node. You must also use the file space name, rather than the drive letter, to select the restore-retrieve drive you want to access. Include the file space name in braces and use it like a drive letter. For example, to restore cougar's files from the \projx directory on the d disk file space to your own \projx directory, enter: dsmc restore -fromnode=cougar \\cougar\d$\projx\* d:\projx\ Use the query filespace command to display a list of file spaces. For example, to display a list of cougar's file spaces, enter: dsmc query filespace -fromnode=cougar For more information about using the fromnode option with the restore command, see Restore. See Retrieve for the retrieve command. For more information about the fromnode option, see Fromnode. *** . *** Restoring or retrieving your files to another workstation When you are using a different workstation, you can restore or retrieve files you backed up from your own workstation. Your backup versions and archive copies are stored according to your node, not your specific workstation. Your Tivoli Storage Manager password protects your data. To restore or retrieve files to another workstation, use the virtualnodename option to specify the node name of the workstation from which you backed up the files. You can use the virtualnodename option when starting Tivoli Storage Manager or place the option in your client options file, dsm.opt, on the workstation. If you are using a workstation other than your own, use the virtualnodename option with the dsm command. For example, if your node name is cougar, enter: start dsm -virtualnodename=cougar You can then restore or retrieve files as if you were working on your original workstation. You can use virtualnodename on commands also. For example, if you want to restore your \projx files to your local c:\myfiles directory, enter: dsmc restore -virtualnodename=cougar \\cougar\d$\projx\*.* c:\myfiles\ If you do not want to restore or retrieve the files to the same directory name on the alternate workstation, enter a different destination. *** FROMNODE and VIRTUALNODENAME options do not document the need to specify a destination filespec to prevent TSM client from trying to recover data to the orignal system's filespace. TSM GUI online documentation: *** Accessing Another User's Stored Data You can display another user's filespaces on the server. You can then restore the other user's backup versions (excluding Windows system objects and System State) or retrieve the other user's archive copies to your local drives. Note: You can display another user's stored data only if the other user has authorized you to do so by using the Node Access List window. To access another user's stored data: 1. Select the Access Another Node choice from the Utilities menu. The Access Another Node window appears. 2. Type the user's node name in the Node Name field. 3. Click the Set button. Considerations: To display your own filespaces, click the Default button in the Access Another Node window. You can also use the virtualnodename option in the client options file to restore or retrieve another user's stored data using the other user's node name and password. Example: virtualnodename puma Restart the client after you add the virtualnodename option to the options file. You are prompted for the password assigned to the other user's node, if a password is required. If you enter the correct password, you have access to all backups and archives that originated from the specified node. You cannot access another user's filespaces on the server using the Access Another User window if you are operating with client node proxy support in which your client node is an agent node acting on behalf of the target node. *** All of the above sections should detail the need for a detsination filespec for restore/retrieve to recover objects if the intention is to recover to the alternate system. Affected Levels: All supported TSM clients Initital impact: Low Additional Keywords:
Always specify a UNC name for restore/retrieve destination when attempting to recover files backed up from a different system to make sure the files are recovered to the expected filesystem.
The need to specify a destination in the case where the data comes from a different machine name is documented in chapter 10 "Restore". It is understood that this is a frequent area of confusion, and alternative means of improving usability or documentation in this area will be considered for a future release. However, a comprehensive solution to this usability issue is beyond the scope of a documentation APAR fix.
