[BBLISA] dump instead of dd for imaging?

[Scott Ehrlich]

I'm working on ways to produce an image of a Linux machine with the Grub boot 
loader, and place the image on an SMB network share.

I've successfully done so with dd, but another admin highly recommends using 
dump, to verify mbr preservation.   I've never used dump for this.

What would be the recommended command line to use dump?

My dd command is:

dd if=/dev/hda | gzip -c | split -b 2000m - /mnt/smb_share/backup.img.gz

I've successfully created the image with the above, then successfully restore 
via:

cat /mnt/smb_share/backup.img.gz.* | gzip -dc | dd of=/dev/hda

I do this booting from a CentOS 4.4 Live CD.

What would be the equivalent for dump?

Thanks.
