Related command

az backup restore restore-disks

Description

Some managed VMs have disks with PE enabled (they have some Disk Access associated). We can now use Enhanced Policy to back them up. During restore, we have the option of allowing public access, specifying a new disk access, or specifying PE with the same disk access. We have added changes that allow for this.
