![]() ![]() Based on a 5% change rate over eight hours that would equate the incremental for a 2.57PB backup. During backup, replication or restore disks of the processed VM are attached to the VMware backup proxy. This graph shows cores to bandwidth required between 1-48 cores with 50% reduction on the egress.Īt 48 cores the ingress bandwidth is ~40Gbps, Egress ~20Gbps for a total of ~60Gbps of packages the server has to process. In the Virtual appliance mode, Veeam Backup & Replication uses the VMware SCSI HotAdd capability that allows attaching devices to a VM while the VM is running. However, as this increases the bandwidth may become an issue both for the ports on the server and the network at large. Veeam Backup and Replication (VBR) has been adopted and selected in protecting IT workloads in the modern datacenter, remote office, and the cloud. With physical proxies it allows for higher bandwidth than could be expected with virtual proxies.įor example a 20-core processor can process at approximately 2GBps or 16Gbps which is reasonable for a single server. Break out to a physical proxy or proxies once the practical limits of virtual proxies are met.A minimum of two proxies for redundancy.Scale-out proxies in sets of 4-cores and 16GB RAM.The recommendations for virtual proxies are: To estimate the resource requirements, the following calculation can be used: 100MByte per second or 5 million files per hour per proxy CPU core. NAS proxy deployment works similar like VMware proxy deployment.
