vYou cannot restore image data from a local backup set (location=tape orlocation=file). You can restore image data from a backup set only from theTivoli Storage Manager server.Related information“Localbackupset” on page 410“Restore” on page 613“Restore Image” on page 634“Restore Backupset” on page 622Backup set restoreTivoli Storage Manager considers a backup set as one object containing the wholefile structure. You can restore the entire backup set or, in some cases, you can selectportions. The backup set media is self-describing and contains all the informationrequired to perform a successful restore.If you are connected to a Tivoli Storage Manager Version 5.4 or later server, yourTivoli Storage Manager administrator can create backup sets that are stacked.Stacked backup sets can contain data from multiple client nodes, and they cancontain different types of data for a particular client node. The types of data can befile data or image data.If you have upgraded from Tivoli Storage Manager Express ® , some applicationdata is also supported.Restriction: Image data and application data restore processing is only availablewhen restoring from the Tivoli Storage Manager server. You cannot restore imagedata and application data from a client local backup set restore.When a backup set is stacked, you can only restore data for your own node. Datafor all other nodes is skipped. When restoring data from a stacked backup set on alocal device, you can only restore file level data for your own client node. It isimportant that the nodename option is set to match the node name used togenerate the backup set for one of the nodes in the stack.Important: Due to the portability of local backup sets, you must take additionalsteps to secure your local backup sets on portable media. The backup set mediashould be physically secured because the backup set can be restored locallywithout authenticating with the server. Each user has access to all of the data onthe stacked backup set, which means that the user has access to data that they donot own, by changing the node name or viewing the backup set in its raw format.Encryption or physical protection of the media are the only methods to ensure thatthe data is protected.If you restore backup set data from the server, individual files, directories or entirebackup set data can be restored in a single operation from the GUI or thecommand line. When you restore backup set data locally, the GUI can only displayand restore an entire backup set. The command line can be used to restoreindividual files or directories stored in a backup set locally.Chapter 5. Restoring your data 187
