    I tried Clonezilla. It seemed to work, but when I installed the backup drive to test it, the OS wouldn’t boot. I later found out about G4L and it has worked properly every time I have used it. I boot from a G4L CD to clone the internal drive to a backup.

    Do try Systemback for cloning. You can end up with an ISO snapshot of your system and after rebooting from it you can do a full restore of itself on target partition. You may find it in recent linuxlire distros too. Enjoy.

    Couple basic problems with your article.

    1. Cloning is cloning – has NOTHING to do with an image. An image may be an intermediate container, but people just want to get from one to the other. So, for your comparison, note those that don’t need an intermediary container. Matters as cloning will be about twice or half as fast if an intermediate is/n’t needed.

    2. Offline (separately booted live cd), or Live (Online) – you haven’t noted which is which in each. e.g. You note doclone is (can be) live, but you don’t also do the same for mondorescue – which on live systems images the drive off to .iso’s, which through a mindi live rescue cd can be fetched across the network. So, is that an image? Arguable, but the point is 1. above – the intermediary container is just that. Not much germane to the topic of your article – cloning.

    I think you need to distinguish the purpose of the clone – migrate (to new drive, be it in place or not), backup (get your system back, perhaps due to file corruption), or live image (guard against hardware failure).

    To that end, you might also consider various forms of mirroring (‘RAID’) as cloning, be it mdm, lvm, zfs, btrfs, or hardware, and backup / file recovery (rsync) as viable mechanisms, depending upon what you’re trying to do. [So, step one, dear reader – Where is it you’re trying to go?]

    Exploring this would seem to be a welcome service. I came across this via googling “linux “live clone”‘ – nicely presented and written article (given caveats above) – expanding on the topic would appear to be worthwhile.

    hands down easiest I have found – and explained is ddrescue

    Mondo backup is the shit. It backs up the OS partition and bootloader to a bootable ISO image. In case of a restore just boot from the iso and its back instantly. I use it extensively.

    Good article.

    Is there any good tool to manage LVMs?
