Compression for NAND dumping

Open Warfields opened this issue 6 years ago • 2 comments

The longest part of the NAND dump appears to be the transfer to the SD Card, Since all of the dump files are ~3.2 Gb is it possible to load it into the Switch's ram (4GB total) and then run compression on it before saving to the SD? Just by using a zip compression i was able to reduce the 30Gb dump down to 604Mb after it was transfered to my machine, this would greatly increase the speed of the NAND dump.

Compression has a lot of overhead though, so it'd slow down the dump if anything.. It would speed up file tranfer though.. it's kinda a catch 22 assuming the compression doesn't slow it down 10 fold.

Ah, that makes sense.
