Linux full Hard disk backup or mirror

charlestsai4001 · 02-14-2008, 07:32 PM

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).

Hello,
Of course it is , allways exist other opportunity to do things.
You can use http://www.dmailer.com/dmailer-backup.html , is a free software that has a lot of features , has good ability to backup / restore process , and if you need online storage they offer that service too.
Hope you will backup and restore as fast as lighting

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):

Code:

nc -l -p 9000 | dd of=/dev/sda

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.

Also there are Partimage and Clonezilla...

Just noticed you mention a scsi hdd, they may not work with those, sorry.
