To boot you need the device to be recognized by the BIOS as booting device. I am not aware of that you can do it with a tape. Yes can do it with a CD.
The DD command will copy b-by-b the whole file system. It can not cross file systems. In summary you can not make the same cd bootable.
There is a zillion way to accomplish what you want. This is my approach:
1. I boot from a usb stick a small distro like dsl-n or puppy. I use the stick because is writable and I can change easy the stuff and even write note for restore etc. Of course you can do it also this part with a bootable CD (live cd linux)
2. From there I do backup restores of the whole system. You can use either dd or tar or cpio. I prefer tar because I have many partitions and I can in one file backup all of them (the same with cpio). With dd is one file per partition/file system.
