I found this addon AutoSaveIncremental after i was looking for something for autosave textures. Since Blender still doesnt have such an option and i see loads of people having issue with this i thought perhaps there is something out there. After going of a thread on Reddit i found this script of yours. Its quite handy but seems unfinished, once its start we can stop it. Add the save location from the preferences works a bit weird perhaps.
But i would like to see if i could use some parts and perhaps make one for textures.
Is that okay with you?
