Rsync

To avoid copying owner/group and permissions from a NTFS

rsync -a --no-o --no-g --no-p --delete -v --log-file=/tmp/rsync2.txt --stats --modify-window=2 --exclude ".encfs6.xml" --exclude "/\$RECYCLE.BIN" --exclude "/System Volume Information" /media/marti/W2000/ /media/W3000LUKS_ENC/

To show stats at the end

--stats

Give a nice overall percentage

--info=progress2

See if a file is tranferred what differs

 --itemize-changes (also in the -vvv)

YXcstpoguax  path/to/file
|||||||||||
||||||||||╰- x: The extended attribute information changed
|||||||||╰-- a: The ACL information changed
||||||||╰--- u: The u slot is reserved for future use
|||||||╰---- g: Group is different
||||||╰----- o: Owner is different
|||||╰------ p: Permission are different
||||╰------- t: Modification time is different
|||╰-------- s: Size is different
||╰--------- c: Different checksum (for regular files), or
||              changed value (for symlinks, devices, and special files)
|╰---------- the file type:
|            f: for a file,
|            d: for a directory,
|            L: for a symlink,
|            D: for a device,
|            S: for a special file (e.g. named sockets and fifos)
╰----------- the type of update being done::
             <: file is being transferred to the remote host (sent)
             >: file is being transferred to the local host (received)
             c: local change/creation for the item, such as:
                - the creation of a directory
                - the changing of a symlink,
                - etc.
             h: the item is a hard link to another item (requires 
                --hard-links).
             .: the item is not being updated (though it might have
                attributes that are being modified)
             *: means that the rest of the itemized-output area contains
                a message (e.g. "deleting")

Compare files by content

-c

By default rsync compares only size and mtime of the file. -c is slow but it ensures that the content is correct

To copy only the timestamps

--size-only --existing

--size-only forces rsync to compare using only the size (not also the time)

Without the --size-only, rsync will detect them as diferent files and transfer the file

To copy only the timestamps (slow)

-c --existing

-c forces rsync to compare files using checksums
