Incremental Backup GUI or Automation Scripts?

[Derek Jarvis]

I read about the Incremental Backup feature here: 
https://wiki.qemu.org/Features/IncrementalBackup

Some of this seems a bit "proof of concept" that requires more 
implementation. Is there an UI available for this, either command prompt 
or GUI, to simplify this process?

My use case is I want to be able to migrate a VM between different 
servers and I want to speed this up by only sending the disk changes. 
The idea is that each server would maintain the "last known" state of 
the disk and would be sent the incremental changes from the other server 
when it is taking ownership of it. For me, one server is a proxmox 
instance, and the other "server" is actually my laptop running virt-manager.

Is there anything available to simplify this process?
