Re: Some help with dd backing up into an iso

Show all headers | View raw

I am getting a little frustrated as neither dd or xorriso work for me as
I wanted.  With the dd and bzip2 combination I got an image really fast
(compared to dd if=.. of=.. ) but when I tried to restore it
dd bs=1M if=/dev/sdb | bzip2 >imagefile
bunzip2 imagefile | dd of=/dev/sdb

it unzipped the imagefile into an uncompress file and burned it ...
although I am not sure what I mixed up in the filenames it restored an
earlier on...

bunzip2 imagefile  -f -t -v | dd of=/dev/sdb

I think this option retains the original compressed image and show what
is doing, although to me the -v is meaningless.

I changed the volume name to sid

$ ls -ld /media/user/sid
drwxr-xr-x 1 user user 2048 Mar  5 20:30 /media/user/sid
$ ls -ld /mnt
$ ls /mnt
usb-Kingston_DataTraveler_3.0_08606E69C773BFC06965007B-0:0-part1
$ ls -ld /mnt/u*

It seems as if it is hardware created and can't be changed

I changed it so it is easier to deal with

Being protective of the setup I have on the little disk I am trying to
restore its image in an identical disk (manufacturer and size)
Only when I get convinced that the restored image is identical (looks
and function) will I be able to go ahead to do more.  No I am worried
I'll ruin all the work and I will not have a last safe image to restore to.
