This section will describe various factors that should be considered regarding this process, and offer several techniques to minimize the impact of snapshot operations.Īs Veeam Backup & Replication leverages the snapshot technology for performing backups, you should ensure it is possible to snapshot the virtual machine disks, since there are certain configurations that do not support snapshots. The creation and removal of snapshots in vSphere creates a significant impact on the environment that must be taken into account. To create VM backups, Veeam Backup & Replication leverages the VMware vSphere snapshot functionality.

This includes applying Windows updates (if using the vCenter Server installable version), vCenter Server patches and upgrades, or any maintenance that would require the vCenter service to be restarted or the system rebooted.
In cases where the backup server and vCenter Server must be deployed across a distance, the only real requirement is that this connection is consistent and reliable. It is generally suggested that the backup server is placed in close logical proximity to the vCenter Server, but this is not always the best deployment option. The backup server must have reliable network connectivity to the vCenter Server.The vCenter Server must be able to handle increased transactional workload to prevent random job failures due to command timeouts. For larger environments, with many concurrent jobs, especially jobs that run at short intervals, the load on the vCenter Server can be significant.If the vCenter Server performs poorly during normal operations, this should be corrected prior to implementing Veeam Backup & Replication. It must be able to answer queries and perform actions in a reasonable amount of time. The vCenter Server must be reliable and always available when backup jobs are running.Having a well-performing vCenter Server with reliable connectivity will mitigate this issue and provide a strong backbone for a reliable backup infrastructure. Problems with connectivity to the vCenter Server is one of the top reasons for failed Veeam jobs.For this reason, fast and stable communication between Veeam Backup & Replication and the vCenter Server is critical to achieve a stable backup environment. Veeam Backup & Replication communicates with the vCenter Server in many operations. While it is possible to connect a Veeam Backup & Replication server directly to ESX(i) hosts, this section assumes a vSphere environment with at least one vCenter Server, and that the backup server is integrated at the vCenter Server level, as this is the best practice configuration in almost all use cases. In this section, we will discuss those interactions and note the items that should be considered for a successful implementation. Much of the implementation success depends on the performance and stability of this environment. Veeam Backup & Replication relies heavily on the vSphere infrastructure it is protecting.
