How to use rsync to copy data from one USB external drive to another

[apparatus]

@leni1

Should I attach the devices to the VM using qvm-block by partition e.g.

qvm-block attach work sys-usb:sdb1

Or attach the full device (for lack of a better term) via sys-usb:sdb

I would like to do the following operation:

You already asked this here:

Not sure how to correctly attach USB external hard drives to disposable VM

As the title says, I am unable to figure out how to correctly attach two USB external hard drives to my laptop that uses Qubes OS 4.2 (with the latest updates installed) I created a disposable VM and then did the following: [user@dom0 ~] qvm-usb attach disp4158 sys-usb:2-2 [user@dom0 ~] qvm-usb attach disp4158 sys-usb:3-1 after which they appear in the qvm-block output like so: [user@dom0 ~] qvm-block BACKEND:DEVID DESCRIPTION USED BY disp4158:sda <device_name> d…

@leni1

Does that need also mounting the devices in the VM they will be attached to as well?

Yes.

@leni1

I’ve just noticed that when I run qvm-block in dom0 terminal, I don’t see the external drives. I only see the hard drive on which Qubes is installed

[qubes_user@dom0 ~]$ qvm-block
BACKEND:DEVID    DESCRIPTION                USED BY
dom0:nvme0n1p2   SAMSUNG MZVL21T0HDLU-00BLL
dom0:nvme0n1p3   SAMSUNG MZVL21T0HDLU-0BLL
dom0:nvme0n1p4   SAMSUNG MZVL21T0HDLU-00BLL

Will try attaching with qvm-usb instead.

qvm-block should show you block devices present in sys-usb as well like this:

sys-usb:sda  DEVICENAME
sys-usb:sda1  DEVICENAME
sys-usb:sda2  DEVICENAME
