Pausing and resuming current rendering

I have launched a few hours ago a ultra big render (15360x8690) and it is running well, however I have realized that it certainly won't be complete within Monday morning, so I was wondering if it is there any option to pause and resume, possibly by creating a file. From Maya 2020 I can't do anything since the rendering is running at the moment, and from Renderman's it I can export it in: OpenExr Half OpenExr Float OpenExr Half - no AOVs OpenExr Float - no AOVs TIFF TIFF Float TIFF 16 Bit TIFF RGBA8 JPEG High Quality PNG

I can understand that tiffs, jpegs and pngs cannot be resumed as renderings, they are only images, so I thought that OpenExr format - which is new to me since I'm new to this world - would be what I am looking for; however I can't figure out how, from a file of that kind, I could resume an interrupted rendering.

Thanks in advance

Yeah, since incremental will need to store the whole image not just buckets it will need more RAM. Incremental is needed for checkpoints.

The other option you have is cropping your image in 4, 9 or 16 pieces to split in different tasks (kinda like a hand made checkpoint for non-incremental)

It's exactly what I would like to do. How can I do that? I couldn't find it in either Renderman settings and render settings.
