Incremental backup also for Virtual Machines
I understand why VMs are always backed up in their entirety when rsync is used for this purpose. For "normal" files, the backup works fine, and only modified files are backed up. However, for VMs, it would be useful to perform the backup at the block level. I found the following regarding this:
If using raw KVM/QEMU, use qemu-img with internal or external snapshots combined with tools like virt-backup or block-pull/backup APIs.
Perhaps others share the same need—feel free to make use of this.
