rsync - Nov 2017 - Rsync to just upload new/updated files without comparing source/destination

Thanks for info. I was under the assumption that rsync will execute
followings steps:
1. Compare first to identify different files (new/updated) --> This is where
i am worried due to data size
2. Upload new/updated files
3 Remove source file

As per your comment, rsync will compare after uploading to check if files
are identical ?

Additionally i don't expect to delete directories as i want to maintain same
directory structure on source. Any insights on if following query will work
effeciently for adding new files to destination
rsync --remove-source-files -av -r <Source Root Folder> ssh
abc at destination.com:<Destination Root Folder>

Assuming 5 TB of data available at destination and source has about 50 files
(New or Updated i.e. files with same name and in same folder), source file
will be removed as soon as it's uploaded.

Thanks

If the source only has 50 files then rsync only needs to check for those
50 files on the target.  If one exists rsync will compare the timestamp
to see if it needs copying.  Yes, rsync verifies a hash of the file
after transfer.

Thanks for your inputs. Surprisingly i tried executing the following command
but end up deleting ssh.exe in Cygwin folder when source folder path is
incorrect or not reachable.

rsync --remove-source-files -v -av -r /cygdrive/c/AmitTest/ ssh
username at destinationserver:/cygdrive/e/AMIT/AmitTest/

I am wondering if remove source is doing some tricks there but unable to
find root cause why ssh.exe will get deleted with this command. It has
happened twice since yesteday and today i noticed this happened when i
executed this command. Any idea why this can be happening?

Unfortunately i don't have way to copy ssh to Cygwin\bin folder as i keep
getting 'Access Denied' error from windows explorer and cmd (tried
taking
ownership of Cygwin folder as well).


Thanks,
Amit
