Error code: 0x80042316 and Error code -2147212522 both represent the VSS error “VSS_E_SNAPSHOT_SET_IN_PROGRESS”.
This error is typically indicative of another VSS-based backup occurring on the guest. This is usually due to multiple backup strategies running simultaneously that utilize VSS. Any utility to create a native backup of an application with a VSS writer may utilize that application’s writer to perform periodic backups.
To resolve, ensure that your disaster recovery processes do not overlap when run via their schedules.
