IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive ...

Restore BackupsetThe restore backupset command restores a backup set from the server, a local file,or a local tape device.Use the backupsetname and location options with the restore backupset commandto specify where Tivoli Storage Manager searches for a backup set during therestore operation. See “Location” on page 283 for more information.If you are restoring a file space from a backup set to a system that did not performthe original backup, you might need to:v Specify a destinationv Use the syntax below to specify the source filedsmc restore backupset backupsetname -backupsetname=-location= {/fsname}/* /destfs/ -subdir=yesYou can restore a group from a backup set with the following considerations:v You must set the subdir option to yes.v The sourcefilespec must be the virtual file space name , followed with aterminating directory delimiter. For example:restore backupset mybackupset /virtfs/* /home/devel/projectb/-backupsetname=mybackupset -loc=server -subdir=yesThe entire group, or groups in the virtual file space will be restored. You cannotrestore a partial group by specifying a qualified source file space.v If you want to restore a local backup set, the virtual file space is not a knownreal file system on the local system, so the sourcefilespec must be enclosed in {}braces, followed with a terminating directory delimiter. For example:restore backupset mybackupset {/virtfs}/* /home/devel/projectb/-backupsetname=mybackupset -loc=file -subdir=yesConsiderations:v You must be a root user to restore an entire backup set from the server,otherwise only files you own are restored.v If you are unable to restore a backup set from portable media, check with yourTivoli Storage Manager administrator to ensure that the portable media wascreated on a device using a compatible format.v If you use the restore backupset command on the initial command line and youset the location option to tape or file, no attempt is made to contact the server.v There is no support in the API for the backup set format. Therefore, backup setdata that was backed up via the API cannot be restored or used.v If the object you want to restore is part of a backup set generated on a node, andthe node name is changed on the server, any backup set objects that weregenerated prior to the name change will not match the new node name. Ensurethat the node name is the same as the node for which the backup set wasgenerated.Restoring backup sets in a SAN environmentYou can restore backup sets in a storage area network (SAN) in the followingways:v If the backup set is on a SAN-attached storage device, specify the device usingthe filename parameter and use the location=tape option. Tivoli Storage Managerrestores the backup set directly from the SAN-attached storage device, gaininghigh-speed restore performance.470 IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
