| 7.3.4 | How to load a software image backup
If you need to load the backup Cisco IOS version, use a variation of the copy command, copy tftp flash, which will allow you to download the image that you previously uploaded to the TFTP server. After you enter the copy tftp flash command, the system prompts you for the IP address (or name) of the TFTP server. This can be another router serving ROM or Flash software images. The system then prompts you for the filename of the software image. The example shows sample output from copying a system image, named C4500-I, into Flash memory. If you attempt to copy into Flash memory a file that is already there, a prompt will tell you that a file with the same name already exists. This file will be deleted when you copy the new file into Flash memory. The first copy of the file still resides within Flash memory, but is rendered unusable in favor of the newest version, and will be listed with the [deleted] tag when you use the show flash command. If you abort the copy process, the newer file will be marked [deleted] because the entire file was not copied and is therefore not valid. In this case, the original file still resides within Flash memory and is available to the system.
