The major new feature of today's FlashFire update is the ability to create backups that can be flashed back to the device with fastboot. This will allow you to restore your phone from your computer without booting Android or even a custom recovery. This is a new and experimental feature, and as such there are a number of ifs, buts, snags, and caveats.
Only the main Android-related partitions are able to be backed up: boot, recovery, system, vendor, oem, userdata (including internal storage), and cache. Radio/modem partitions need some further investigation and testing, while bootloader (and other not mentioned) partitions will probably never be supported.
As the userdata partition generally contains both /data and internal storage, you should be aware that if you choose not to backup internal storage, restoring the userdata partition through fastboot will leave you with an empty internal storage.
As with backing up the internal storage normally in FlashFire, backups and other files from FlashFire, TWRP, CWM and MultiROM are skipped.
The backup of userdata is currently always in unencrypted ext4 format (even if you are currently running encrypted f2fs). If you restore it, you will end up with an unencrypted ext4 device - a pro for some, a con for others. You need to be aware that stock Marshmallow+ kernels may refuse to work with an unencrypted userdata partition. A SuperSU-patched boot image should work fine though, and chances are, that is included in your backup. Both encryption and f2fs support are under investigation for future versions.
Fastboot backups are truly meant to be restored from your PC using fastboot. While you can 'install' the backup ZIP file using the 'Flash firmware package' option, that currently does not support flashing the userdata partition, which is usually the most important partition to backup/restore. There may be support for this in the future, though.
The backup itself is a ZIP file containing partition chunks (similar to Motorola's sparsechunk format) and a flash-all.bat file to perform the restore. The commands in that batch file should also work on Linux and OSX, but regardless of platform, the fastboot command needs to be on the PATH, and support the -u switch (which all recent Android SDK versions do). Obviously, your bootloader also needs to be unlocked for the flash to work.
Last but not least, this feature has only been tested with a handful of devices, while there are a great many devices out there that support fastboot. It might not work well or at all for your device.
Other noteworthy changes
When flashing a ZIP or OTA, there is now the option to 'Preserve recovery'. This will backup your current recovery image before starting the action, and restore it afterwards. This option is automatically enabled if FlashFire detects you have TWRP or another custom recovery installed. With this feature enabled, you can have TWRP survive an OTA flash, even if FlashFire restores the stock boot and recovery to let that OTA succeed.
A pretty severe issue with SurfaceFlinger has been identified and worked around. This issue could cause FlashFire to black screen indefinitely rather than performing the flash or rebooting. This might not fix all black screen issues, but it will fix some.
I've also finally gotten round to implementing the Credits listing, which details the used libraries and binaries and their authors and licenses. I'll cower behind the BETA tag for not taking care of this sooner.

Nice!!, will just do a backup and transfer the zip to my desktop, can be handy in an emergency.
Very, very nice, dude. This thing is pure awesomeness at its finest.
Since I never had / use MO / MOP, can't wait for the paid link for this to support your work again. Until that happens, thanks!

THANK YOU so much,you helped me so if it wasn't for you I would never have received supersu. Ps i do not know much English so wrote through a translator.
Thanks for the root
+Chainfire Thank you! I been trying to use your app and I noticed when you do Wipe, then ROM then GAPPS it would fail. It seems not to put the steps in the order as I added them. When I moved the Wipe to the beginning then it worked fine. I used on my FIre 7" tablet and hopefully tonight I'll Try on my Note 3.
I like it

Any chance of getting Flashfire to make Odin flashable backups?
Oye como comfiguro el super su ?
For some reason I can't flash a rom on to my kindle
Is it possible to flash Android N with flashfire?
Como salen en facebook ahh ?
Great info here. At this point, I've used Flashfire to update my Nexus 6P. I do know how to use ADB and fastboot.
Can I simply flash the new radio, or must I do both the bootloader AND the radio at the same time?
Also, will flashing the bootloader image unroot or lock my phone? I'm a bit unclear on the effects of flashing the updated bootloader after using Flashfire. I just want to have all the most up-to-date images.
