Additional notes on offline backups with VSS
This topic applies to the NetBackup Hyper-V VSS backup method only (not to WMI).
When an offline backup is performed on a virtual machine that is currently in the Running state, note: the virtual machine briefly enters the Saved state during the backup and then returns to its original state.
For a virtual machine in the Running state at the start of the backup, the type of backup is offline in the following circumstances:
The VSS integration component of Hyper-V is not running in the virtual machine.
The VSS integration component is part of the Hyper-V integration services that are installed in the virtual machine.
The virtual machine is running an operating system that does not support Windows Volume Shadow Copy Service (VSS).
The storage configuration of the virtual machine is not compliant.
Any of the following can result in a non-compliant storage configuration:
The virtual machine has one or more disks that are configured as dynamic disks in the operating system. Note that dynamic disks are not a type of virtual hard disk. Dynamic disks and basic disks are disk types defined by Microsoft for certain Windows operating systems.
The virtual machine has the volumes that do not support Volume Shadow Copy Service (VSS).
If the virtual machine has a non-NTFS formatted volume (such as FAT or FAT32), the virtual machine enters the Saved state during the backup.
