backup (dd disk cloning)

Hi

I using Ubuntu on my A110, just 8GB ssd. And wanto make a backup, by cloning the disk

Using the command "dd", to copying the whole disk to a file (on an external usbmemory).

Code:

dd if=/dev/sda of=/media/usbmemory/somefile.img

(see http://en.wikipedia.org/wiki/Dd_(Unix) )

This does something. BUT i have not bean able to verify the files integrity by mounting it virtual.

Code:

mount -t ext4 -o loop,ro somefile.img testdir

Maybe its too big, or maybe ext4 filesystem dont like running from dumps. Dont know. Any hint on this???
(see http://ubuntuforums.org/archive/index.p ... 85560.html, but that didnt work for me)

Is it possible to copy the whole ssd -disk onto a bigger usb-memory, say if=/dev/sda of=/dev/sdb. And then maybe resize partition table with say "parted". And use the new usb-memory as the prime disk, that may work as an liveCD (or liveUSB) on other intel -computers??

What other nifty backup option are there? Anybody using the original Limpus "AA1BACKUP"??

 

Try out Clonezilla (it uses DD as an option) or if you want a more point an click backup solution there is Redo Backup http://redobackup.org/ I have used Redo and it works great
