Ask about backup


Can anyone tell me about backup technology.

I'm need to do a backup for the security issue, which backup the image from the original harddisk to another new harddisk.

The planning for disaster, if anything disrupts is happening for the original harddisk and the backup harddisk will be replaces in my linux box.

Some linux expert, recommended to use "dd" command.

Can someone tell me from the beginning step.

Example what should I do for my new harddisk?
and I can I implement the "dd" to copy whole the file system
to new harddisk

I properly can found this from the goooooggle.

But could someone tell me the details the step to implement it.

I've a new harddisk now. What should I do from the begining step.
... plug and mount the hardddisk, should I need to format it.
before I can do the dd copy the image file to my new harddisk.

What the "bs", behind the "dd if=/dev/from_partition of=/dev/to_partition"
example dd if=/dev/from_partition of=/dev/to_partition bs=18k.
