Step 2: Setting Up Free Space Monitoring

Another matter of great importance is repository sizing and capacity planning. It requires consideration of two primary factors, space and I/O performance. For details, you can refer to the "Best Practices for Veeam Backup & Replication Deployment and Configuration" document.

It is recommended that you have a mechanism in place that allows you to configure a threshold for repository free space and automatically notifies you before the situation becomes critical. With no headroom for new backups and recoveries, your DR strategy may become compromised. Also, a means for capacity planning will be of use – it can help you to analyze the historical and current storage utilization data and estimate the amount of additional space that needs to be provisioned to accommodate the necessary restore points.

A backup administrator should track free space available on the backup repository and get notified of decreased space before the limit is reached. Veeam ONE Monitor allows you to automate this course of action.

Take the following steps:

1.In Veeam ONE Monitor, open the Alarm Management view. You can either search for the alarms on backup repository, or select the Backup repository free space alarm from the navigation tree under Backup & Replication > Repository.

2.Click Edit in the Actions list on the right.

3.On the General alarm property tab, make sure the Enable this alarm check box is selected.

4.On the Rule tab, make sure the Enabled check box is selected. In the Rule parameters section, you can configure the threshold value for repository free space to trigger a warning and an error state (measured as a percentage of overall repository capacity). Default values are:

10% free space left – for warning

5% free space left – for error

For evaluation purposes, you can set these limits, for example, to 30% and 20%. After finishing the evaluation case reset them to defaults — for smooth test lab operation.

5.On the Actions tab, make sure the Send email to a default group is selected – this should be the group you have populated when setting up for Step 1: Setting Up Availability Monitoring above. Ensure it includes a mailbox that you have access to.

6.Click OK to close the dialog.

Backup repositories tend to run out of free space due to poor sizing, or if the retention policy is too relaxed – outdated restore points clutter the datastore and decrease storage capacity depletion.

1.To populate the repository, you can, for example, create a backup job for a large-sized VM; you can use the backup job settings to modify retention so that it includes more restore points. You can also use the backup import feature and other possibilities to saturate the repository.

2.Open the mailbox you have configured as default recipient for alarm notifications. The mailbox should contain the item from the corresponding sender (veeam_one@mycompany.com in our example), with the subject line containing [Veeam ONE Monitor] Alarm – Backup repository free space from <repository_server_name> and alarm details and KB.

3.In Veeam ONE Monitor, open Data Protection view and on the Alarms tab and make sure the Backup repository free space failure alarm has been issued by the machine hosting your repository.
