About protecting against network link failures
The majority of backup traffic is transferred over network connections with 100 MB and 1Gbit speed which provide transfer rate of around 8 MB/sec and 65 MB/sec, respectively. To make network links highly available, deploy redundant network teaming. Due to cost considerations, network teaming is often restricted to backup servers and mission critical clients only. Non-mission critical clients have single network connections and the risk of connection failure (and the subsequent failure of the backup) is accepted.
