[pve-devel] [PATCH_V2 pve-zsync] fix bug #813: allow mountpoints or VMdisk which are not on zfs, if they are not include in backup.

LXC: MP are in the default setting exclude from backup, so we do not sync mp at default.
if they have the flag backup=1 we sync them.
QEMU: VMDisk will be synced always except they have a flag backup=no.
