Command for Copy - Mountpoint

Stoker · 29. März 2017

Hi guys!
I just switches from XPEnology to OMV and because of that, I have to copy a hole lot of Data from one Drive to an other.

I wanted to do that via PuTTY, but I don't know how to do that. I know that I should be able to copy files with

Code

cp -a /source/path/. /destination/path

I tryed that, but can't get it to work.
My to Drives are called "dev/sdb" and "dev/sdc"
My Shared Folder (the Source) on these drives are called "Filme" (sdb) and "Filme_1 (the destination on sdc)

I need to know what code exactly I have to type in to get all the Files from sdb to sdc, or all the files from "Filme" to "Filme_1"

Could you please help me

P.S.
I did that via rSync for now, but it seems to be kind of slow and in the Futere I want to use the Linux command.

Other than the initial index, rsync should be just as fast as the copy command. I actually use rsync because it is easier to restart and you can see progress.

Hard to give you an exact command if we don't know the mount points.

Ok, where can I see the Mountpoints then?
With Rsync (started in the GUI) it took 11 hours to copy 1TB of Data from one drive to an other. Furthermore my CPUwas at 50-70% and that is a Xeon 4 Core CPU.

Did you mount them with the OMV web interface?

Are there a lot of small files? cp shouldn't be any faster. With a xeon, the rsync and cp commands are limited by disk speed.

The files have a Size from 700mb - 8 TB.

All of your filesystems look correct in fstab. So, you can look in each of the /media/LONG_UUID directories to see where your files are. Then:

cp -rfv /media/SOURCE_UUID/SOURCE_FOLDER /media/DEST_UUID/DEST_FOLDER

Thanks for your reply, but where do I find the UUIDs?

Did you look in /media/? The tab key will auto-complete instead of typing the entire uuid.
