local data discovery

[bstone108]

I'd like to see resiliosync acquire this feature.  an example of it can be found in syncthing.  Basically, if data that's being synced already exists in another file, or in another share, instead of transferring that same data over the network again, it can instead be copied from the existing file or files, from this share or any other located on the same machine.  In addition I'd like to see improvements to the trash, as often a file that was trashed because it was deleted or moved, isn't properly detected and copied or moved to its new location.  I believe this local data discovery feature could resolve that too by keeping hashes of the data in the trash and pulling from the trash folder of any share if the data is a duplicate of what's being added somewhere else.

i understand that taking parts of a file might be more complex but if a whole file already exists it would be great if it wasn't transferred again. i just copied a folder within a share and ALL data was transferred again even though every hash could have been known.

And I agree with the trash. So many files end up in there because of a move operation and would be great if it was improved

It is also implemented for the partially changed files and for the multiple instances of files, see Diff delta sync and File deduplication features:
