Managing Upload Streams
By default, Veeam Backup & Replication uses multithreaded data transfer for every job session. VM data going from source to target is transferred over 5 TCP/IP connections. However, if you schedule several jobs to run at the same time, load on the network may be heavy. If the network capacity is not sufficient to support multiple data transfer connections, you can disable multithreaded data transfer or change the number of TCP/IP connections.
To change the number of connections:
- From the main menu, select Network Traffic Rules.
- In the Global Network Traffic Rules window, specify new data transfer settings:
- To disable multithreaded data transfer, clear the Use multiple upload streams per job check box. Veeam Backup & Replication will use only one TCP/IP transfer connection for every job session.
- To change the number of TCP/IP connections, leave the Use multiple upload streams per job check selected and specify the necessary number of connections in the field on the right.
