This is not as simple as checking a box and clicking next (it is if you do the pre-reqs correctly). Please note, while this seems simple, a lot of pre-reqs must be successfully completed in order to utilize this great feature. Proper Planning Prevents Poor Performance!

This feature allows to protect the volumes (globally for Enterprise edition, and individually for Enterprise Plus edition) from high latency, by monitoring and adjusting backup load accordingly. In a cluster of 8 hosts, each hosting the same amount of protected VMs, this makes a task limit configuration of 2 per host, thus limiting the impact per host. The backup load will automatically be spread over all Hyper-V hosts.Įxample: Let’s assume sizing calculation results in 16 CPU cores being required to achieve your backup window. While consuming production resources for backup purposes, the On-Host backup mode disadvantages can be mitigated by the following guidelines. Limiting the impact of On-Host backup mode on the production infrastructure No impact on the compute resources on the hosting Hyper-V ServerĪdds additional delay for snapshots transportationĭepends on stability of third party VSS provider Requires additional resources from the hypervisors (CPU, Network IO and RAM) during the backup window, for IO processing and optimizationĭoes not require additional hardware, load is spread over all Hyper-V hostsĬan be used on any Hyper-V infrastructure Wherever feasible the recommendation is to use on-host proxy mode. This memory must be available for running backup jobs, otherwise the Hyper-V Host will start paging, which will result in an overall slow system.

Please be aware that you will need up to 2GB of RAM on the Hyper-V Host per running task (one task = backup of one virtual disk). However, the Veeam data mover agent will consume host compute resources for deduplication and compression, so this needs to be considered when planning the Veeam Job design.
#Veeam backup from storage snapshots windows
When using Windows Server 2016 or later, On-Host proxy mode is very fast and requires less components, thus reduces complexity. Performance wise, since both backup modes are using the same Veeam transport service, the only differentiating factors will be the additional time requested to manage transportable snapshots (in favor of On-Host mode) and the balance between compute and backup resources consumption during backup windows (in favor of Off-Host mode). Intensive checks of vendor VSS provider during POC are highly recommended (cluster environment). It is important that the VSS framework provided by the storage vendor is tested and certified to work with Microsoft Hyper-V clusters. Off-Host backup mode works for virtual machines hosted on SAN storage or SMB3 compatible storage. It leverages transportable shadow copies using hardware VSS provider provided by the SAN storage vendor or SMB3 functionality.īackup mode availability depends on the underlying virtualization infrastructure.
