When should I use Speedkit and which hypervisor does Vinchin Backup & Recovery support?

SpeedKit is a Vinchin unique feature which can be used as a CBT alternative for backing up VMs in high speed mode.

When SpeedKit is enabled, a snapshot needs to be reserved for each VM for faster calculation of the VM increments. If you have sufficient production storage, it is recommended to enable SpeedKit for efficient incremental backups.

Currently, The hypervisors Vinchin Backup & Recovery support are RHV, oVirt, OLVM, Citrix Xenserver, SANGFOR HCI and Openstack.

Notice that you can either use CBT or Speedkit for speeding up incremental backup.
