Well the only way to get a CWM backup or TWRP backup would be to first unlock the bootloader on the device, but since you can't get into fastboot to actually unlock the bootloader their is no safe way to flash a CWM or TWRP nor is their a custom recovery compiled for this device, you cant just flash any twrp or cwm build and expect it to function since they need to be compiled for each device independently in other words the CWM and TWRP are device specific and when you build either one you have to specify which partitions the specific device your building for is using for various things such as the system and boot etc. And these partitions vary from device to device, I am not sure what the app does that updated either, but for sure do not try to flash twrp or cwm unless it has been built for your specific device and you wont ever be able to without an unlocked bootloader since 6.0 uses dm verity etc if you flash custom recovery or rom to this device without the unlock in effect it will most likely soft brick at the very least. In the past their were ways to kind of sideload roms from the external sd card but that from what I know of is no longer an option unless someone figures out a new way to bypass the newer security checks, I am not going to say they never ever will but it will take some time at the very least....From all the times I have messed with rooting and customizations on android through the years I would say your safest bet in the future is to make an educated purchase before you decide to buy a new phone if you for sure want to be able to root and use custom anything like roms and kernels then you need to find out beforehand is your device going to support bootloader unlocking officially or is their already an exploit that will enable you to do so in existence at time of purchase, I find if the unlock is not supported officially then you would probably want to get a flagship device as the devs and exploit gurus typically work it out on those devices first and steer clear of ATT devices or Cricket as they rarely get the support from the community for things of this nature due to the total lockdown methods att seems to use on their devices in the past years to present. I would recommend HTC or Motorola as they seem to support unlocking officially on many more devices than other manufacturers and even still you may have to buy them directly from them vs the carrier as the carrier has the option most of the time to lock the bootloaders and customize the roms the way they want with all the bloatware etc. T-Mobile is also usually unlocked as well or at least easier to figure out a way to get unlocked vs ATT or Verizon, I am not sure about some of the smaller carriers but I think Metro PCS also has alot of devices that you can get unlocked fairly easy. I hope this sort of enlightens you to what exactly your asking for and educates you a little more for future reference. I am using Cricket as my carrier due to the cheaper price, no contracts and they use ATT towers which seem to have best reception in my area but their devices suck if you want to root and unlock the bootloader as they use the same firmware as the ATT phones and those too are mostly locked tight and most of them you cannot even get into the stock recovery without a no command message which does you no good at all, so I mostly order my devices from the net directly from the manufacturers and inquire beforehand on whether or not they support bootloader unlocking on them, or you can find good deals on swappa.com or sometimes ebay just make sure they are the right variant of the device your wanting, because sometimes you for instance have the LG X Power which on Cricket you cannot even get to Fastboot to even try to unlock the bootloader but on T-Mobile their variant probably would allow you to access it, the device would also be called LG X Power but the actual variant number would be different so you really gotta check all those things first. I really wanted to dev for this device too, but I quickly noticed that the chances of someone getting the thing unlocked were slim to none therefore I decided to move on. It is sad as the X Power does have some great potential to be made alot better with a custom kernel etc. but their is nobody with the knowledge needed really working on it at this time that I know of.
