    Macrium and dual boot system.


    Have been using Macrium for some time without problems, to backup Windows. Now I would like to know if it will backup a dual boot system, specifically Windows 1909 and Ubuntu 20.04. Has anyone had issues doing this?

    It can backup Linux partitions but I think (not certain) that it cannot compress them i.e. it is a bit image. @jimbo may know.

    Makes sense. I Have a 256 GB usb 3.0 flash drive, which has plenty of space. As always I appreciate all help.

    I have a multi boot system with Win10, Linux, and Win7. Each OS resides on its own SSD but I run Macrium from within the Win10 OS but I have separate scripts for each system that backs them up to different folders on a NAS. Since they are all run from within Win10 each is compressed as it should be when the backups are run. However, you could just as easily back them up all at once to a single location but I prefer to have them separate as it makes for better housekeeping.

    Hi there @Hewjr100

    caveat to beware of

    Macrium will back up dual boot systems perfectly OK so long as you haven't set anything up as "Logical Partitions" -- so Macrium needs to see for example your Ubuntu partition as say Disk "D".

    Remember also that a typical Linux system will have these partitions itself on the Linux partition : /boot, /, /home (you don't need to backup swap areas).

    Macrium will then write image as "physical" format - so it won't be as quick as backing up Windows and it will take more space.

    Restoring to a different Disk can be problematic with some Linux Distros -- Grub might need updating or / and fstab might point to wrong /dev/sdx partition numbers on the new disk -- that's easy enough to fix though - edit /etc/fstab manually with VI from a Live distro. Some distros restore perfectly -- for example Fedora 32 --I have moved it around a lot (and between systems - not as a VM but a physical OS) and it boots every time -- I think it uses UUID's for disk so restore always works.

    Cheers

    Was not aware of this. Mine is seen as Healthy EFI System, Healthy C: Drive, and Healthy Primary Partition

    Already did full backup, is there a way to test it,before actual restore?

    You could mount the backup file and see if you can browse the partitions. You can also use vBoot to create a VM from the backup. Kari wrote a tutorial about doing that, very handy.

    Hi there
    @Hewjr100

    To backup that system on to different media so you can use it without having to restore your entire image :

    The best way in this situation is to do the following :

    1) boot any Linux live distro.
    2) Mount the windows disk (the one with partitions "C" and "D" -- assuming "D" is the ubuntu partition.
    3) on the live distro issue lsblk command. You should see a whole set of /DEV/SDX partitions
    4) you should be able to determine the Ubuntu "Disk" with its partitions -- you might have 3 or 4.
    5) attach an external device to the system - needs to have at least the size of your Ubuntu system -- a decently sized USB stick is sufficient.
    6) as root run following command :

    dd if=/dev/sdx<x is the number of the ubuntu partition -- the top one not the lower levels> of=<dev/sdy<y = nr of ext drive> bs=64M status=progress.

    Job now done !! -- then try booting the drive you've just created. It might need a grub makeconfig -- not sure about ubuntu -- depends whether the /boot (or /boot/efi if efi system) partition on ubuntu is totally on the ubuntu partition or whether the Linux boot rec is on the boot area of the resident HDD.

    You can see that by booting to your Ubuntu system ("D") and using GPARTED or whatever tool you have for partitioning on the Linux system check the flags on a /boot partition -- on EFI it should be flagged as boot,msp while on MBR it should be just flagged as boot.

    Cheers
