Veeam compression ratio calculator4/11/2023 This is the reason why the WANĪccelerator consumes significant amounts of CPU and RAM resources. The WAN acceleratorĬomponent will then process those data blocks with much more efficient data deduplication and compression algorithms. The WAN accelerator uses its own digests based on the hashes of the blocks inside a VM disk, which means that it reads data from the backup files and re-hydrating them on the fly, or it reads directly from the source VM in case of replication. For more information, refer to the WAN Acceleration section of the Veeam Backup & Replication User Guide. When using WAN acceleration on links with very poor bandwidth, you may have to manually seed the initial copy to the target. To determine whether WAN acceleration is necessary in an environment, it is important to understand what particular savings can be achieved. Any other WAN acceleration technology should be disabled for Veeam traffic. This technology is specifically designed to accelerate Veeam job. Variable block size deduplication and global caching, WAN acceleration provides sufficient capability whilst the required network bandwidth is dramatically reduced when performing Backup Copy and Replication jobs. By combining multiple technologies such as network compression, multi-threading, dynamic TCP window size,
