This chapter explains how to restore data from the Tape Server while the Storage Server is stopped.
The Tape Backup of AdvancedCopy Manager can restore a backup history on tape media on the Tape Server even while the Storage Server is stopped.
Histories on a disk can be restored only while the Storage Server is active.
This function is useful in cases such as the following.
If all volumes including system volumes on the Storage Server are damaged, transaction volume data is recovered in parallel with operating system construction. This can reduce the time taken before resumption of the system service.
The table below lists the restoration functions that can be used while the Storage Server is stopped. All these functions can be executed on the Tape Server.

Display backup history information on tape media and determine the data to be restored. In an environment having multiple Tape Servers, only the backup history managed by the Tape Server on which the command is executed is displayed. Backup history information managed by other Tape Servers cannot be displayed.
For details of the command, see "Tape history information display command (tbohistdisp)".
Restore by specifying a backup data history stored on tape media.
This function implements restoration without preprocessing and postprocessing on the Storage Server.
For details of the command, see "Tape restore command (tborestore)".
The tborestore command does not check whether the Storage Server is stopped. It restores data directly to the transaction volume without performing preprocessing and postprocessing on the Storage Server. For this reason, restored data is not guaranteed if restoration is performed while the Storage Server is busy with transactions. Execute the tborestore command after making sure that the Storage Server is stopped or is not accessing the restoration target volume.
Use the tboexecstat command to check the status of restoration from tape media.
The command shows the progress of reading from tape in the [Execute] field.
For details of the command, see "Tape Server execution status display command (tboexecstat)".
