There is no ETA, but the patch is currently going through the submission process with Sony and Microsoft.

On PS4 you can back up saves to a USB flash drive.
On Xbox One you only have the option to copy saves to MS' cloud servers, and would need to play while not being logged in to Xbox Live in order to control when and if the Xbox would sync saves (you might be able to disconnect if you die in the game, quit, delete the save on the colsole and then reconnect and log back in to Xbox Live to sync the honour mode save version from the previous session).
