I know there was talk at some point about compression options (like adding zlib compression back in, or being able to set compression settings).
It might be nice to have an option to exclude certain file types from being compressed. I had several large (250M - 500M) files that were already compressed. Re-compressing them with lz4 (or any other future option) doesn’t seem to provide much benefit.
To expand on this (and because I already typed the text that allowed the discourse to find this existing topic):
Most data (by volume) of what most home users back up are compressed media files. These files are incompressible. Attempting to compress it is 100% waste of battery life.
It would be great if duplicacy allowed to specify file types (by extension would be easiest, but also by data inside (see man file)) that would bypass compression.
