During a backup, large amounts of data are transferred through the networks and can cause a slowdown of business-critical operations. Network administrators use various approaches to minimize the impact of backups on daily operations. Among those are scheduling backups off the business hours and traffic-reducing techniques such as data compression and forever incremental backups. However, one of the best ways to optimize backup traffic is the segregation of production and backup networks. One of the possible approaches to do this is a LAN-free backup. The most common techniques used in virtual environments are direct SAN access and HotAdd.
