I'm temporarily using my daughters 4s since mine went underwater. how do i back up my data on her phone without overwriting her backup file in icloud?

Question

my 4s went in the ocean this past weekend. ugh. guess it was time enough to switch to a 5 anyway. so i commanderred my daughers 4s to use as my own for a week or so while i get the new 5. I backed up her data to our family shared icloud account (7 devices and 50g), and then deleted and restored from my own backup. i also changed the name on her phone to my own. but, now when i look at the backup management on icloud, it shows her backup with "this device" under and my new name on it. I expect if i back up to icloud now it will not overwrite the back up i restored it from, it will overwrite the most recent back up of this device, which was her final back up. how do i back mine up- perhaps just to itunes for a week or so, until i can restore her back up back to her phone?
any help would be appreciated.
thanks-
dad in trouble...

If this is your first sync and there is already data on the phone, perform the steps listed below.  This will transfer your apps and other media purchased from the iTunes store to your iTunes library, perform a manual backup and restore, then sync the iTunes media back to the phone from your iTunes library.  This will not transfer media from other sources such as music from your ripped CDs.  As you said you never synced before, I assume all of your apps, music and other media was purchased from the iTuens and App stores.  If this is correct, you won't lose anything.
Download and install iTunes: http://www.apple.com/itunes/.
Launch iTunes, go to the View menu and click to check Show Sidebar.
Go to iTunes>Preferences>Devices (Edit>Preferences>Devices if using Windows) and check "Prevent...from syncing automatically".
Go to Store>Authorize This Computer and authorize all Apple IDs used to purchase apps and other iTunes media (music, podcasts, movies, tv shows, etc.) on your phone.
On her phone, go to Settings>iCloud>Storage & Backup and turn iCloud Backup to Off.
Connect her phone to your computer and in iTunes go to File>Devices>Transfer Purchases to transfer your purchased media to your iTunes library.
Right-click on the name of the phone on the left side of iTunes and click "Reset Warnings".
Right-click on the name of the phone again and click "Back Up" to back up the phone.
Right-click again and choose "Restore from Backup...", select the backup you just made to restore from and restore the backup to your phone.  If prompted to back up again, decline.
Go to the Info tab and make sure nothing is checked so you aren't syncing calendars, contacts, etc. with iTunes.
Go to the Summary tab and select This Computer under Automatically Back Up.
Check the other tabs to confirm that your sync settings are the way you want them.
Click Apply at the bottom to sync your phone.
