I'm not quite sure what you're asking. Can you perhaps rephrase it? Are you asking how to backup a Recovery partition or how to create one or ??? Do you know how to backup the Mavericks partition?

The above are different ways to do what the "clone" type programs that Eric Root talks about - the clone products are fine for duplicating the entire disk, but I'm not very familiar about their details (don't know if they backup all partitions, including the special hidden ones, or ???) - but these clone backups won't be much help to restore individual files (easily that is) like Time Machine can (that's my opinion anyway), but are better at restoring entire disks or volumes I think.
Have you done a Time Machine backup of your system yet? Did you do it to another external disk? If you don't care about user files, a virgin Maverick's installation takes about 15GB (I'm guessing as I don't run Mavericks - 15GB is based on Yosemite virgin install I recently did), so you don't need much for it (this size estimate DOES NOT include /Users folder which can be quite large nor does it include any applications not a normal part of OS X which can also be quite large). The Recovery Partition is about 650MB total (but this is a compressed volume and expands to about twice that when you boot from it).
Try this command in a Terminal window (Terminal.app is located in /Applications/Utilities):
diskutil list
It will print out all the disks and their partitions and sizes and types on your system - shows the special hidden "EFI" and "Recovery HD" partitions along with the normal partitions like / and others that might, or might not, be a part of the system.
But make sure you understand what to do before you do anything destructive to your disk so that you can get back to what you have now - there is no longer any way to download the Mavericks Installer app from Apple, so if you want to run Mavericks at any time in the future, you need to backup your current Mavericks install before you erase the disk - and make sure you verify the backup to make sure it is readable. Would probably be a good idea to practice restoring your backup to another disk (other than the Mavericks disk you just backed up) and see if you can boot from this practice disk before attempting to install Yosemite. That way you know you have a way back if you don't like Yosemite or have big problems with it like some people have experienced.
Good luck...
