CBT metadata vdi in XenCenter Storage Virtual Disks

Robert Madrian



we use Vinchin Backup with CBT to backup our VM's - in XenCenter Storage Virtual Disks I can see now second vdisk for every VM vdisk with 

the same name but no Size and Virtual Machine Name...

if I use  xe vdi-list on that SR I see that this disk are of type=CBT metadata

so is this the normal behavior in XenCenter?
