Camera Raw: Save raw at lower resolution
I have a large megapixel camera which I use for all my shooting. However for certain shoots or for certain images, I do not need my camera's full resolution image stored in raw, because it occupies significant space (both locally and for backup purposes).
Why is there no feature to save at a reduced pixel dimension?

You'll have to take that up with your camera manufacturer. It's not something Adobe raw converters are able to do as you request. Adobe treats proprietary raw data as read only.

Interesting idea. However RAW data come directly from sensor along with some metadata about lens, setting, location etc.... By itself not human perceivable as an "Image"- it needs to be processed. So the only practical way to export a smaller version that "image", the data would be to process and scale it. At which point it basically what happens when you shoot direct to JPG + scaling.
I guess one could perhap make an argument for in camera or software conversion to some uncompressed / or lossless format high bit count (16 or 32 bit), TIFF... But that would not be much better than just shooting a max quality JPEG as a first generation master. (I.E. Not recompressing derivative generations. )

You can convert the raw files to DNG with Adobe DNG Converter and then use lossy compression.

I agree it could on occasion be useful to produce DNGs at a lower res than the original camera raw file. For instance - animation/film production - to be able to go straight to 4k DNG would be great for Timelapse.
