Problem backing up IOS.

I would like to backup my IOS but having some issues as follows -

 

What I noticed is that if I do >Sh Version, I see the following -

 

''System image file is "flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin".

 

If I do >Sh Flash, I see the following -

 

C3550-ipservices-mz.122-35.SE5 - Which I think is not valid coz its not a .bin file???

 

I don't know why Flash shows this and version shows something different.

 

What should I copy? Should I copy -

 

1 - c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin

 

or

 

2 - flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin

 

or

 

3 - c3550-ipservices-mz.122-35.SE5.bin

 

Please help!

    You don't see a .bin because it's a directory.  The full path is  flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin so either change directory to  flash:c3550-ipservices-mz.122-35.SE5 or use the full path when you are copying it.

    you probably need to use forward slashes:

     

    cd  flash:/c3550-ipservices-mz.122-35.SE5/

    Are you familar with DOS... all you are doing is moving into or "changing directories"

    just follow joshua's directions...  cd means change directory... it will put you in that directory... if you get lost use

     

    pwd

     

    that means print working directory... pwd shows you what directory you are in...

     

    cd .. (enter) will bring you back to the root direcory... check out some basic dos and linux commands for filesystems... ios uses a few of them

    You should have ROMMON access to the device.  This should allow you to boot from the image. So if you do a

     

    rommon> dir flash:

     

    It should show you what folders are in flash. You can then issue the boot command with the full path.....which would be something like

     

    flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin

     

    Here is a trick to learn with CIsco IOS - it is an easy way to tell if what you are looking at is a directory or an IOS.  First off, does it have ".bin" at the end of the name?   If not, check how large the object is, if it's small, you're looking at a directory.  On current Cisco IOS they do not show the full size of the directory and it's contents when you do a "dir filesystem".

     

    It's kept me safe for years now.....
