Hello, <context> I am trying to backup openvz containers from a Proxmox server. Proxmox provides a tool called vzdump. It handles snapshoting the container, packing config files and stuff for me. It outputs a tar on stdout. I wanted to pull this tar with backuppc, but I figured out that backuppc can't handle the .tar made by vzdump because of sparse files inside. </context>

Is this a bug or a feature ? If feature, any reason for not supporting sparse files ? Am I reporting this at the good place ?
