Restore

Restoring a disk from the tape takes place in the same way as saving, only in the reverse
order. The menu for selecting the tape device (see
has been selected the tape archive is read and the menu for disk or slice selection displayed
(see figure
tape. If a disk is selected which is not on the system, an error message to this effect is
displayed.
The disk partition table for the backup is then compared with that for the physical disk. The
result of the comparison can be one of the following:
1. The disk partition table for the backup is the same as that for the disk to be restored.
Restoring is possible without repartitioning the disk.
2. The disk partition table for the backup differs from that for the disk to be restored. The
conditions are then checked to determine whether the backup can be recorded onto the
disk. There are two possibilities here:
a) The disk to be restored has the same geometry as the disk from which the backup
b) The disk to be restored does not have the same geometry as the backed up disk.

105). The disks or slices displayed are disks for which there is a backup on the
was generated. In this case the disk which is to be restored must be at least as large
as the backed up disk. If this is the case the following query appears:
Restoring to otherwise partitioned disk, do you want to continue?
If acknowledged by Y (for Yes), PSR regenerates the disk partition table.
The following message appears:
Copying to disk with different geometry, do you want to continue?
After the message is acknowledged with Y (for Yes), the disk partition table for the
disk to be restored is adapted to the backup. The condition for this is that the target
disk is large enough for the changed disk partitioning. This condition is checked
after adaptation of the disk partition table. The disk is then partitioned and the
backup recorded.
