Once discovery is completed it is recommended to protect your applications from the Hycu applications view. Same backups will also protect the complete virtual machine and will be visible and available for file-level and VM restore from the Hycu VM view.
If starting backup through the Hycu Applications view, it is Hycu that ensures the respective application consistency without the need of installing additional tools on the client VMs.
When starting backup through the Hycu Virtual Machines view, Hycu creates an application consistent snapshot of the Virtual machine using Nutanix v3 API’s. VSS based application consistency is ensured by utilizing Nutanix NGT tools installed on the client machine. If NGT tools are not installed, or fail for any reason, Hycu will still continue to backup, but will perform a crash consistent snapshot. What type of snapshot was taken can be seen in VM view by hovering over VM Backup status icon and checking Consistency.
