Veeam Backup & Replication 7.0 introduces the enhanced data compression algorithm that is capable of very high throughput with significantly lower CPU utilization, if compared to default compression used in previous versions of the product, while achieving similar levels of space savings (typically within 5-10%).
Due to significant reduction in CPU utilization, using this new compression algorithm will allow proxies to run 2x as many jobs per vCPU/core, achieving even better performance. For example, a virtual proxy with 4 vCPU was previously recommended to run only 2 concurrent jobs — and now with v7, this same proxy will be able to easily run 4 concurrent tasks. However, since it will be running 2x as many tasks, the proxy may need additional memory resources:
•With versions 6.x, typical recommendation for proxies was 1GB for every vCPU/core.
•With version 7.0, 2GB per vCPU/core in minimal recommended — however, you will need half as many proxies.
