Hi, Is there a way to backup KVM Guest VM in kvmguestosimage.ova or kvmguestosimage.vmdk format as I am trying to restore it in AWS by referring to https://aws.amazon.com/ec2/vm-import/ article as per the below supported file format. [1] Open Virtualization Archive (OVA) [2] Virtual Machine Disk (VMDK) [3] Virtual Hard Disk (VHD/VHDX) [4] raw Also any method to take full and incremental backup of KVM Guest VM. Any help will be highly appreciated. I look forward to hearing from you. Thanks in Advance. Best Regards, Kaushal

Since you are not adding any metadata, then why not just use the raw image since I presume openapibox.img is in raw and not qcow format. If it is qcow, then you can convert it to raw and use that. The disadvantage of the raw format is also the fact that most tools will not keep the sparseness, so you might end up with a high storage usage. Maybe you can try vhdx instead since that *should* just be a disk image.
