Acronis 2019 and Ubuntu
Does the Acronis 2019 bootable media allow you to back up and restore Ubuntu partitions, which in my case are in EXT4 and UEFI?
Because I wish I could use Acronis 2019 for my Windows 10, and for my installation of Ubuntu?
Nathanael, simple answer is yes, all recent ATI versions are able to backup & restore Ubuntu EXT4 partitions. I do this myself on my laptop which is setup as dual-boot with Windows & Ubuntu 18.04 LTS and have the Ubuntu partition backup created from within Windows. I also use the ATI Rescue Media to backup a dedicated Ubuntu computer by booting from that media.
Acronis should only fall back to using sector by sector backup mode if there are issues detected with the EXT4 filesystem. My own backup does not show as using sector by sector mode for the EXT4 partition.
You should look at using fsck in the Ubuntu system to check the filesystem.
UEFI should make no difference here to either Acronis or Ubuntu - this is purely the BIOS system and denotes how the system is booted to launch the OS.
How does the size of the backup image compare to the size of your Ubuntu EXT4 partition?
My own partition is 21GB and the backup image is just over 4GB for a used size of around 8GB on the EXT4 partition.
