I have been looking at different tutorials about rsync about some specific situation I have.

I have a home server with all my pics, this server is my backup, my PC is the one that receives the new pics and until now i had been manually copying and pasting new photos from the PC to the server.

I was trying to setup rsync to do this automatically and in principle, it does without problem.

Now the issue; when I fire up rsync it start copying all the files, even the ones were already in the destination (this is because it is the 1st sync).

so my question is: Is it possible for rsync to verify that a file is the same (name/size/bin) so it will skip the copy on the 1st sync?
