Backup set restore

Edit online

IBM® Storage Protect considers a backup set as one object containing the whole file structure. You can restore the entire backup set or, in some cases, you can select portions. The backup set media is self-describing and contains all the information required to perform a successful restore.

If you are connected to the Tivoli Storage Manager 5.4 or later server, your server administrator can create backup sets that are stacked. Stacked backup sets can contain data from multiple client nodes, and they can contain different types of data for a particular client node. The types of data can be file data or image data.

Windows operating systems If you have upgraded from Tivoli Storage Manager Express, some application data is also supported.

Restriction: Image data and application data restore processing is only available when restoring from the server. You cannot restore image data 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. Data for all other nodes is skipped. When restoring data from a stacked backup set on a local device, you can only restore file level data for your own client node. It is important that the nodename option is set to match the node name used to generate the backup set for one of the nodes in the stack.

Important: Due to the portability of local backup sets, you must take additional steps to secure your local backup sets on portable media. The backup set media should be physically secured because the backup set can be restored locally without authenticating with the server. Each user has access to all of the data on the stacked backup set, which means that the user has access to data that they do not 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 that the data is protected.

If you restore backup set data from the server, individual files, directories or entire backup set data can be restored in a single operation from the GUI or the command line. When you restore backup set data locally, the GUI can only display and restore an entire backup set. The command line can be used to restore individual files or directories stored in a backup set locally.
