Cloning an entire Linux drive from TBWINPE with IFW

[Sand_Paper]

Hello,

I'm trying to clone an entire 250GB Linux drive, it's a Debian based system, with GPT scheme and LVM, it's also the drive from where the system boots..
I've disconnected it from the PC where it belongs and connected it via USB to a notebook, the destination drive is connected to the same notebook via eSata and it's larger than the source (500GB). I've booted a TBWINPE Win10 MBR USB key on the notebook and I'm tryng to clone the entire drive with the copy command..
My questions are:
-If I need to do operations on a Linux based hard drive/system is it better to use an IFL based usb key or is it the same using IFW?
-To clone the drive with IFW (also with IFL if it fits better) have I to be careful with some specific options to make it boot and work like the previous one?

Thanks

assuming everything is standard you may need the Assume Original HD option since it's linux and target is not same as it is on the system it will go in (although grub for gpt is different, but won't hurt to use it). The restore would be the same, just if you want to mount/access it using linux tools you'd want to be under linux.

Thanks for your prompt reply!
It's a Proxmox backup server (Debian based), I have to upgrade the OS "in place" so to have a plan B if the upgrade transforms into a nightmare I wanted to clone the system to another drive, boot it (on the same hardware) and try to upgrade. If anything goes wrong I'll reinstall the old drive.

if it's non standard you can always do entire drive copy with backup unused sectors which causes a raw 0-n copy.

Thanks, I'll try the "Assume Original HD" option and if it doesn't work I'll do a RAW 1-1 copy.
