SecuROM 7.33.0011 Backup?

I have an original CD which has SecuROM 7.33.0011 and would like to make a physical backup copy in case something happens to the original.
I’ve read some guides on here but they seem to be for older versions of SecuROM.
Does anyone know if it is possible to make a physical backup of this CD and if so how would I go about doing it?

Thanks in advance for any help.

If it’s a cd not a dvd, see here or here.

Thanks for the link, I’ll try it out.
I saw that but didn’t think it would still work over a year after the guide was posted.

but what about the dvd? i know it also use alcohol 120%,but dont know the detail,any one can help me out?
