Suppression, silence mode, summary notifications and rule timing to cut unwanted Veeam ONE alerts.
From Ultra Transcenders VONE-13 by Tony Rough (coming January 2027)
Veeam ONE offers suppression during known activity, silence mode for maintenance, modelling against history and notification batching to stop alarm storms burying the alerts that matter.
| Option | Scope | When it applies | Notes |
|---|---|---|---|
| Silence mode | An object, or a container and all its child objects | Manually until exited, or on a schedule (once, daily, weekly, monthly) | Suppresses all alarms on the object and also Veeam Intelligent Diagnostics log analysis |
| Veeam Backup activity (alarm Suppress tab) | VMs being processed and their hosts and datastores | While Veeam Backup & Replication jobs process the VMs | vSphere and Hyper-V alarms only; needs a connected backup server |
| Snapshot creation / deletion (Suppress tab) | The object or its parents | While the hypervisor creates or deletes a snapshot | vSphere alarms only |
| Suppress alarm based on schedule (Suppress tab) | The alarm | Weekday time intervals | Intervals on the same day must not overlap |
| Guest disk suppression | Selected guest OS disks of a VM | Always | Only for Guest disk space alarms |
For alarm-specific suppression, Veeam ONE shows no notifications and runs no actions while suppressed; if the object is still affected when the suppression period ends, the alarm triggers and its actions run. The Veeam Backup activity option is precise in scope: selected on a VM CPU usage alarm it suppresses only VMs being backed up or replicated, but on a Host CPU usage alarm it suppresses the whole host while any VM on it is being processed.
A silence mode schedule entry can apply to child objects and carry a comment of up to 512 characters. Disabled schedule entries stay listed but are not applied; Exit Silence Mode ends a manual or scheduled period.
| Tool | What it does |
|---|---|
| Alarm modelling | Applies current alarm settings to historical data (week, month or year) for chosen objects and forecasts how many alarms of each severity would be raised; started from the main menu Modeling, an object’s Alarms > Modeling, or selected alarms in Alarm Management |
| Severity tiers | Warning and Error rules on the same alarm so only the higher threshold is urgent |
| Ignore after / Trigger after | Event-based rules can fire only after repeated events and stop repeating until resolved |
| Aggregation type | Min with “Above” fires only on sustained breaches |
| Existing alarm rules with delay | An alarm built on another alarm fires a set delay after the source alarm triggers |
| Other notification policy | Groups alarms into a summary email every interval (30 minutes by default) |
| Notification conditions | Errors only on noisy channels; disable resolved and acknowledged emails |
| Exclusions | Remove objects that are expected to breach |
Common trap: Relying on “Veeam Backup activity” suppression for Veeam Backup & Replication alarms - it applies to vSphere and Hyper-V alarms only, and only when a backup server is connected; snapshot suppression is vSphere-only.
