is there a filesystem that constantly looks for ways to compress data using a small amount of processing power?
particularly i'm looking for a way to dedupe files within various archives (.bz2, 7z, .zip) across many drives, or otherwise the compression method finding a more efficient way of compressing similar byte streams
i want to be able to copy a file to the new filesystem and then if it's a duplicate byte stream that the compression filesystem would eventually compress it, to the point that it may as well be a symlink
ideally, when first copying a file it wouldn't be compressed, or otherwise a very small amount of compression (level 1) and then gradually reprocessing the file up until maximum compression (level 9) while always having read/write access
filesystem needs to have read-write access at all times for all files
