[SOLVED] What's the best/secure way to clone a 2TB hdd in linux?

Hi!

I have a very large internal SATA hdd (2TB) that's filled with my own private vinyl rips which is of course very valuable to me.

In the past i've used external hdd's to backup the 2TB in smaller partitions but I want to clone the entire 2TB hdd to another newly bought storage capacity.

Since the 2TB is stored on my server (no x server) i'm looking for a terminal application that will serve my hdd cloning needs.

commands I will not be using in terminal:
cp
dd if

Why? Because copying 2TB takes a long time, and since there's no output from cp or dd that's a no go option for me, and i've had issues of stalling file copying with linux before.

Summarized: What's the best (terminal) application you can recomend that will clone my hdd 100% with some sort of output (eta on transfer, debug etc).

I'm assuming when the clone is done, i can just simply take the cloned hdd and put it everywhere by just using a standard sata and it will show up just like any other hdd right in the operating system?

Thank You

dd will actually show you progress if you know how to ask it to do so, see this wiki article: https://wiki.archlinux.org/index.php/Se … s_Checking

I would recommend that you use rsync for this task.  For example:

rsync -avu --progress /path/to/source /path/to/destination

You can try ddcfld instead of dd

duplicity/rsync is the best way imo. More efficient than dd, and with the added advantage that you can change the partion scheme/filesystem etc easier.

graysky cheers for the rsync suggestion, i'm already backing up all my files using rsync!

I love dd as a low level file format but using it as a cloning takes way too much time for my own taste, i'm just gonna rely on rsync instead.

ddcfld <--- is this on aur, no results on a simple search

Cheers guys

Glad you got it - rsync rocks for these tasks.
