The error "Snapshot provider error (0x173D): Backup is in progress. Please wait for backup completion before trying this operation again" appears during a backup of a virtual machine or files that reside on a Cluster Shared Volume (CSV)
Snapshot provider error (0x173D): Backup is in progress. Please wait for backup completion before trying this operation again
When backing up a virtual machine or files that reside on a CSV, Backup Exec prepares the CSV for backup to avoid data corruption. During the preparation, the controlling node is moved and pinned to the cluster node on which the backup runs. The default amount of time to move the node is 2100 seconds (35 minutes). However, the process may take more than 35 minutes if the System Snapshot Provider is used and active backup jobs that target the same CSV are running on other cluster nodes. If the node cannot be moved within 35 minutes, then the job fails with the above error message.
- Retry the job.
- Schedule the backup jobs to run at different times.
- Increase the amount of time that is available to move the node.
