After you restore a disk image, you may want to restore any files that had been added or changed since that disk image was created. When you do, you use the ADSM backup-archive client and use the IFNEWER option for the restore operation. This restore operation adds or replaces files on the disk. Any files deleted after the backup are still restored. Therefore, it is possible that the disk may not have enough space to contain all of the restored files.
Delete or move files to make sufficient space available.
