Implement Pull based approach #11

Open abbbi opened 10 months ago

abbbi commented 10 months ago

Currently qmpbackup uses the push based approach, which can only work by dumping the data to a certain directory, this means the utility has to be executed on the same system running the qemu processes.

With the pull based approach (NBD based), remote backup would be possible, but nbd client functionality needs to be implemented, too (like for virtnbdbackup)
