Is there a better solution for Linux full hard disk backup or mirror. Because I am planning to change my
Linux server's hard disk (I don't want to re-install
and re-config all the setting).
My system is Fedora Core5, SCSI HDD *4 (Raid 5+hot spare)
Dell Poweredge 2850 server.
Is there any opensource software for this function like Windows ghost? Please advised.
Thanks
The dd command can make an exact copy of one disk to another. There is a long-running thred at LQ in re using the dd command. It will clone everything from the MBR to the end of the object disk (or the target disk if it's smaller than the object disk).
Netcat is also a really handy utility for cloning drives as it allows you to do the transfer over the network (make sure you have a fast connection) without putting copy-from and copy-to drives in the same machine.
Basically, you do do this...
On the machine you are copying from:
Code:
dd if=/dev/sda | nc 10.1.1.2 9000
On the machine you are copying to (assume ip is 10.1.1.2):
Distribution: Ubuntu/Debian, CentOS, RHEL, FreeBSD, OS X

If you need a bit by bit copy of your current hard drive (clone), essentially the following example command accomplishes it:
Code:
dd if=/dev/sda of=/dev/sdb
This assumes sda is the drive your cloning and sde is the backup.
