Ok, to backup the IOS of the 2960, you have but two choices.
1. Easy: Go to the Cisco website and download the exact version of IOS found in your 2960 switch. This way you download the complete TAR file and not just the BIN file.
2. Not that easy: Presume that your TFTP server is up and running, you need to go into the subdirectory of the IOS found in your flash. The command to go into the subdirectory is: cd flash:. Once you've done this, issue the command "dir" and you'll see a file with the extension BIN. This is what you need to copy into your TFTP server. Issue the command "copy flash:.BIN tftp:///".
To upgrade the IOS to your switch, you must make sure that you have enough space to put a new IOS in. Go to the Cisco website and download the IOS version and make sure you have the file that has an extension "TAR".
To "copy" the new IOS into the switch and overwrite (or erase) the old IOS, use the command:
