Lambda, thanks that was very informative read, and by using piping with other commands its wonderful what little data dump can achieve us.

But the issue with dd is that it also dumps the unused space, it makes raw dump which is not acceptable.

Isn't there any thing more "intelligent" ?

Thanks.

[lambda]

that's the point of "disk imaging" -- copy everything, even empty space.

you could use the ext2/ext3 dump command to do backups instead.

[DivineLight]

Wonder why people do that, assuming that ext2/3 dump can also restore proper image, but intelligently

Hi,

Have you guys given a try to Bacula, http://www.bacula.org/

Well according to my experience, Clonezilla is the best offline backup solution available.

I dont like the solution,

Can I know why?

is there anything available like Norton Ghost for linux?

Yes. Its clonezilla and its not platform based, its offline backup utility. Believe me "There is no solution (even licensed) even close to clonezilla." Norton Ghost is bull****

khizer: Thanks for emphasizing on Clonezilla, actually I overlooked it in a hurry. It looks promising, I have downloaded the .iso and soon I will try it out.

Thanks again

Yes but its usefull for backups especially if you want taped incremental backups (correct me if I am wrong)

but other than that, you must try rsnapshot. If you are using lvm then LVM snapshot + Rsnapshot is a KILLER, it can provide consisten backups of live servers

You are welcome!

Well clonezilla has saved my a** countless times. It has numerous features and amazingly reliable. If you are a sys admin responsible for one or more servers(win or linux/unix), this is a must have and trust me its a life saver.

It has features that you wish you have, for example:

-Clone the whole partition/harddisk with MBR
-Clone the whole partition/harddisk with MBR and create a stand alone recovery cd/dvd (amazing feature)
-more than 8 compression options for the cloned image
-place the cloned image on -> local hdd or usb hdd or remote ssh/ftp/sftp/samba/nfs server
-restore the cloned image to multiple servers simultaneously using multicasting! (amazing feature)

and the list goes on and on

I'll surely try it soon and describe my experience here

PS: Can you please tell me whats LVM? I know there's an option while installing to setup LVM while partitioning but I don't know whats the benefit of it. Thanks.
