I would use dd to copy the disk. It will fail once the 64GB drive is filled up, but it's likely that it was copying empty space at failure, so the copy should be fine. You have nothing to lose by trying.

I don't know how to use dd to copy
do you have any links, where does it explain how to do it, or a tutorial?
In clonezilla the EXPERT mode must be used in order to clone to a smaller drive. Replacement main drive

Welcome to Linux where we have these things called man pages that provide the documentation for programs. To see the dd man page, in the shell type:
man dd
Press the space bar to see the next page. Press the q key to quit.
Many man pages are also available online. To see the dd man page, google search for it in your browser.
After you have read the documentation feel free to ask any questions.
SaviorCalabro I really don't want to scare you, but with dd it is quite easy possible to do a lot of things wrong (e.g. unintentionally overwrite existing partitions) which can cause serious problems. So be careful and read the docs first as gderf has suggested.
thank you gderf cabrio_leo
but I would like to do a safe job, I was thinking of installing debian 9.11 x64 on an 80GB HDD
Then clone everything under debian
what do you think of this idea?
Exactly what is you intend to accomplish with this?
Exactly what is you intend to accomplish with this?
use debian, to install clonezilla and Gparted
and clone disks via USB
using the debian terminal
what do you suggest me?
You are seriously overthinking this.
Clonezilla and Gparted are both already available within OMV. Look in The OMV-Extras section Kernel area. So you could just use them from there.
But you could more easily use dd in the shell to clone your OMV system disk to the 64GB SSD. As I said initially you have nothing to lose by trying this. Just be careful.
use dd in the shell to clone
you want to tell me, directly from the shell from the NAS where OMV is installed
do I connect the keyboard and the monitor and do it from there?
entering with root and password
root @ xxxxxxxxx: ~ #
is this what you want me to understand?
You don't need to connect a keyboard and monitor. You can ssh into the machine from another machine that has a keyboard, monitor, and has network connectivity.
How and from where have you been interacting with OMV?

from win 10 via chrome

That would be via the OMV web interface. What you need to do requires using the Linux shell, or stated in another way, you need to get "under the hood."
You can do this several ways.
If you have a monitor and keyboard attached to your OMV this is called the console.
If not you can connect to OMV from another machine via the secure shell, or ssh using a program like Putty.
There is or was a plugin for OMV called shell in a box. That would probably be the easiest way if it exists.
I say pick one 
If not you can connect to OMV from another machine via the secure shell, or ssh using a program like Putty.
I just installed Putty
I put the IP, root and password
formidable
Thank you very much
now I document myself, for how to clone OMV on SSD
Be careful when you are logged in as the root user. root has full control over everything and there is little if any protection from making mistakes that can have major consequences up to and including destroying the operating system.
Read and try to understand the dd man page and/or google for information on how to use dd to duplicate disks. There are many sources for this information.
Pay particular attention to matters concerning being absolutely positively sure about the device you choose to be the output of the dd command. There is no sanity checking, no popup warnings, no "Are you sure Y/n? prompts, etc.
dd shows no mercy. The output device will be completely overwritten with no possibility of recovery. If you chose the wrong disk as the destination, too bad so sad.

I am going to clone the large sized disk
so you don't miss the OMV system
I have another hard drive of the same size
so first clone it with clonezilla
then I try to transfer to small SSD
Exactly what are you expecting to happen when you run that dd command?

I did this:
Boot into CloneZilla
Enter Shell
sudo su
fdisk -l (to ensure disks)
then if I understand I have to do this
dd if = / dev / sdb of = / dev / sda bs = 512 count = 1 (to detect partitions)
Reboot
Boot into CloneZilla
device-device mode
beginner
part_to_local_part
sdb1 as source
sda1 as destination
skip checking / repairing source file system
yes twice
rerun
device-device mode
beginner
part_to_local_part
sdb2 as source
sda2 as destination
skip checking / repairing source file system
yes twice
Remove CloneZilla
Reboot
Success!
I believe these are the steps
