Situation: The client has a problem to run Veeam backup with this error:
Creating VSS snapshot Error: Failed to create snapshot: Backup job failed. Discovery phase failed.
Cannot start empty snapshot set. VSS error: VSS_E_SNAPSHOT_SET_IN_PROGRESS. Code:0x80042316
Error: Failed to create snapshot: Backup job failed. Discovery phase failed. Cannot start empty snapshot set.
VSS error: VSS_E_SNAPSHOT_SET_IN_PROGRESS. Code:0x80042316
Troubleshooting: 1. Based on Veeam website: This error is typically indicative of another VSS 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.
2. Run vssadmin list writers to check any errors.
