What is the state of the art software in disk imaging?

Postposted on Tue Feb 28, 2012 4:12 pm

I need to wipe one laptop and create a disk image for backup, and I would also like to have a regular backups of my primary PC.

Because I'm mainly using Linux now, and I will need to create safe partitioning software when I'll need to install Windows on secondary partition at some time, I need bit-by-bit backup/restore solution.

Preferably one that can create VHD images as well. Bit-by-bit is even more important because some partitions are fully encrypted in Linux system.

I remember Norton Ghost was the best 8 or so years ago, but I haven't been following the software lately. Also, I don't need a smart fancy-pants-sits-in-a-tray-uses-licence-for-each-tray solution. I want a software I can use for 2 PCs, boot with boot CD, mirror to NAS/(secondary HDD)/VHD. Reboot, restore from NAS/(secondary HDD)/VHD.

Is there anything that works like that?

Good old dd will make bit-for-bit images. Any Linux LiveCD should have it, and if your NAS supports NFS there's your remote filesystem support.

But what about VHD and different size partitions, partition tables?

Can't do that, but it's free and does the bit-for-bit that's your #1 goal.

You've got multiple requirements. One is backup of systems, another is backup of partitions, and a third is partitioning and storage setup.

The last two are the territory of clonezilla or gparted - both available in small bootable systems

for system backup, something like rsync or similar doing snapshots on a regular basis is usually a bit better way to go.

Redo backup is very friendly. (http://redobackup.org/) It's based on partclone, like clonezilla I believe, which is block level imaging.

If you need a bit level image, dd is what you want. It will create an exact image of the drive, and it looks like you can boot the image in KVM. (http://blog.sviluppoweb.eu/2010/07/16/h ... x-qemukvm/)
