Re: [orca-list] Does anyone know of a program for backing upa computer that works with orca?

I may have asked this some time ago but don't remember the outcome. If I use dd to backup say a 40GB partition but decide to restore it to a new larger hard drive and have room for larger partitions, how can I restore this original image to that newer bigger partition? I would think that image would force the target partition to the original 40GB size. I'm looking for an easy way to migrate my system from one older drive to a new larger one.

Yes, indeed. The obvious logical next step is to combine the imaging and
compression into a single command.

I didn't go that far because I surmised that explaining the individual
parts would be helpful. However, pipes and redirection provide wonderful
opportunities to simplify tasks to a single command, and this is a
straight forward example.

I would caution that the bunzip will probably take a lot of time.
Indeed, dd will take quite some time, but the bunzip even more. You
might want to do this overnight.

Hi Janina,
As a suggestion, the following command:
dd if=/dev/sda3 |bzip2 >/home/backup.img.bz2

You use the dd command either in a terminal window or from a console.
You should be root to backup a partition. Assuming the partition you
want to backup is mounted at /dev/sda3, you might use a command like:

dd if=/dev/sda3 of=/home/sda3-backup.img

This will create a file in /home, called sda3-backup.img, which will be
an exact, byte by byte copy of your /dev/sda3 partition.

Clearly, you must have sufficient free space on /home for this to work,
so check that with:

df /home
df /dev/sda3

For long-term storage, you will probably want to compress this file,
perhaps like this:

tar cjpf sda3-backup.tar.bz2 sda3-backup.img

I typed dd and lost speech. I'm sure there is more to that command, can you give me a idea how to use it?
What I have is a windows partition that I want to back up and restore when I replace the hard drive.
Thanks Mike.

You don't need a special distribution. Try using the 'dd' command that
has been there in Unix and Linux systems forever. Note you can also tar
and bunzip the result to reduce the size of your backup image file.

Hi, this may be a little off topic, but I need something that works with Orca, so thought this was the place to ask.
There are some Linux distributions like PING-2.01 aimed at providing tools for backing up a partition. Does anyone know of a program for ghost or backing up partitions I can install in ubuntu or what ever distro that works with Orca?
Thanks Mike.
