I do a "clone" from one mounted disk to other disk mounted remotely.
I will cal them local and remote.
Local is slackware,and remote ubuntu
On local

df -h /mnt/
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/fedora-root 49G 4.3G 43G 10% /mnt

On remote

 df -h /media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29
Filesystem Size Used Avail Use% Mounted on
/dev/mmcblk1p2 57G 7.2G 47G 14% /media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29

I see rsync is not done the things properly,after use this command
from local

cd /mnt
 for i in * ;do rsync -avP --delete --ignore-errors $i/ 192.168.0.75:/media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29/$i; done

I see for example on local

file bin
bin: symbolic link to usr/bin

and on remote..

file /media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29/bin/
/media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29/bin/: directory

I want bin destroyed on remote and it must become(as on local) a symbolic link
Which option for rsync?
Using:

rsync -avPl
rsync -rvPl

doesn't work

The -l (-links) option is implied by -a (--archive) but you also need -K (--keep-dirlinks) so that target directories are allowed to be symlinks. You may find that you also need --delete-before to correct the existing structure.

rsync -avKP --delete --ignore-errors src/ 192.168.0.75:dst/

Looking more closely at your original code, you're iterating across what I now see is the top level of your server, including /bin and /usr. In this instance /bin is a symlink to /usr/bin, but your code passes this to rsync with $i/, which equates to /bin/. So rsync never sees this as a symlink because your $i/ has already dereferenced it.

Removing your for loop and letting rsync handle the full directory tree itself will allow it to see the top-level symlink and transfer it correctly.

I found a nice "workaround"

Instead of did

cd /mnt
 for i in * ;do rsync -avXHhP --delete --ignore-errors $i/ 192.168.0.75:/media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29/$i; done

I do

rsync --avXHhP --delete --ignore-errors /mnt/ 192.168.0.75:/media/ubuntu/1c34a414-9fa2-4bfe-a57c-7f82f1b31b29 ; done

And work,the dir are identical even on symlinks

Edit: I correct with -avXHhP,which is more good for backup bootable
