Server hard drive is about to crash

My server hard drive is getting alot of errors.

I talked to the people providing the server and they told me to make a backup of the drive and let them know when its done so it can be replaced.

I have 2 hard drives, and one I mounted as home2 but its empty.

I tried to configure backups to run and backup to it, but it wont work because it says there is no /home2 lol

I'm really really bad at linux and I have no idea how to ghost the drive to the 2nd, and then back again, and the worst part is doing it remotely.

Anyone have time to offer some instructions?

Thanks

Here is the command line I'm going to use for this

Let's assume we have to clone a harddrive (sda). Which has a partition table setup below. It has 1 NTFS partition loaded with WinNT/Win2K and rest Linux partition. (swap, Linux and Raid partition). Assuming second (slave) harddrive (sdb) is also attached to the same system.
Device Boot Start End Blocks Id System
/dev/sda1 1 9 72261 83 HPFS/NTFS
/dev/sda2 10 75 530145 82 Linux swap
/dev/sda3 76 467 3148740 fd Linux raid autodetect
/dev/sda4 468 2200 13920322+ 83 Linux

A simple way to clone this drive (/dev/sda) to another drive attached to this system (/dev/sdb) is to use dd command.

dd if=/dev/sda of=/dev/sdb

This command will copy each bit from sda (Master drive) to sdb (Slave drive) including MBR (Master Boot record). Thus after cloning new drive (sdb) is ready for deployment. This will also copy any information like File System IDs etc.
