In some cases, the SP may need to perform service actions with the SP backup infrastructure, for example, upgrade a server whose resources are consumed by tenant VM backups and replicas. Such operations may require that the SP cloud resources become temporarily unavailable to tenants and tenant activities are temporarily put on hold. Starting from Veeam Backup & Replication 9.5 Update 3, to make the SP environment ready for maintenance, the SP can put its backup server to the Maintenance mode.
The Maintenance mode functionality is supported in the following Veeam products:
- Veeam Backup & Replication 9.5 Update 3
- Veeam Agent for Microsoft Windows 2.1
- Veeam Agent for Linux 2.0
The Maintenance mode functionality allows the SP to do the following:
- Gracefully stop currently running tenant jobs targeted at a cloud repository of the SP. The following types of jobs are supported:
- Veeam Backup & Replication jobs:
- VMware vSphere and Microsoft Hyper-V backup jobs
- VMware vSphere and Microsoft Hyper-V backup copy jobs
- VMware vCloud Director backup copy jobs
- Backup copy jobs for Veeam Agent backups created in the Veeam backup repository
- Veeam Agent backup jobs
After the SP puts the SP backup server to the Maintenance mode, Veeam Backup & Replication checks the status of tenant jobs targeted at the SP cloud infrastructure and does the following:
- If a Veeam Backup & Replication job is performing, Veeam Backup & Replication allows the currently running task of the job to complete. All subsequent tasks in the job will fail. This helps make sure that backed-up data pertaining to a certain VM or VM disk is successfully transferred to the cloud repository before the SP starts service actions in the Veeam Cloud Connect infrastructure.
- If a Veeam Agent backup job is performing, Veeam Backup & Replication allows the job to complete. This helps make sure that backed-up data of the Veeam Agent computer is successfully transferred to the cloud repository.
- Prevent tenant jobs from starting.
If a tenant starts a new job session at the time when the SP backup server is operating in the Maintenance mode, the job will fail.
- Notify tenants about maintenance in the cloud infrastructure.
In the statistics window of a tenant job that completes with the Failed status at the time when the SP backup server is operating in the Maintenance mode, an error message will be displayed informing that the SP backup server is under maintenance. By default, an error message contains the following Maintenance mode notification: Service provider is currently undergoing scheduled maintenance. The SP can choose to use the default notification or create a custom message. To learn more, see Customizing Maintenance Mode Notification.
Consider the following:
The Maintenance mode does not affect other data protection and recovery tasks available in Veeam Backup & Replication and Veeam Agents.
- In Veeam Backup & Replication, a tenant can successfully perform the following tasks targeted at the SP cloud resources at the time when the SP backup server is operating in the Maintenance mode:
- Run a VMware vCloud Director backup job targeted at a cloud repository provided by the SP.
- Run a replication job targeted at a cloud host provided by the SP.
- Perform any data restore task with a backup created in a cloud repository provided by the SP (for example, entire VM, VM files, VM disks or file-level restore, and so on).
- Perform any task with a VM replica on a cloud host provided by the SP (for example, partial or full-site failover, failback to production, and so on).
- In Veeam Agent for Microsoft Windows and Veeam Agent for Linux, a tenant can successfully restore data from backups in the SP cloud repository at the time when the SP backup server is operating in the Maintenance mode.
