[NOTE]
====
When you restore a backup of VMs, you might notice that the Ceph storage capacity allocated for the restore is higher than expected. This behavior is observed only during the `kubevirt` restore and if the volume type of the VM is `block`.

Use the `rbd sparsify` tool to reclaim space on target volumes. For more details, see link:https://docs.redhat.com/en/documentation/red_hat_openshift_data_foundation/{product-version}/html/managing_and_allocating_storage_resources/reclaiming-space-on-target-volumes_rhodf[Reclaiming space on target volumes].
