201 +Since proxmox backup server uses chunks for deduplicating data a complete file list is required. This makes it impossible to download a single file representing a VM or LXC, all files must be downloaded and imported into proxmox backup server for reconstruction.

203 +It also seems like there are a LOT of files shifting - being added and deleted. Making the diff uploaded to jottacloud huge.
