Synchronize two folders in both way; criteria: last changed
 

Hello,

First I'll explain the situation: I have an archive folder with images,
text and other type of files. I used to backup this folder from time to
time but at some point I stop doing that and got confuse (or messy:) and
start to edit files in the backup and/or to add files to the 'current'
folder.


I'd like to rationalized that by synchronizing the backup and current in
both way:


- keeping only the version of the files which have been the most
recently changed.
- if a file or a subfolder is present in one folder and not the other
I'd like to always keep it.


I look into mann rsync but I'm always asked to choose one source and one
destination, which is obviously not what I want to do. Is there a way to
do that with rsync? How?


Maybe with another software?

can someone give a hand?
Cheers!
