Configuring Threads and Network Bandwidth

In this article

    Veeam Backup for Microsoft 365 allows you to configure threads and limit download speed.

    To specify the number of threads and limit download speed, do the following:

    1. On the General tab, do the following:
    • In the Set the number of threads to field, specify the allowed number of threads.

    A thread defines the total number of proxy server threads that are responsible for handling data transfer to/from backup repositories. By default, 64 threads are used. Depending on your environment configuration and capacities (low CPU or RAM deficiency), running too many threads may significantly reduce the efficiency due to possible throttling errors or connection failures. As every production environment operates under different equipment capacity, Veeam Backup for Microsoft 365 allows you to explicitly define the number of threads that your infrastructure is potentially able to handle without losing performance.

    • Select the Throttle network traffic to check box and specify the average download speed.

    For example, if you have set this value to 10 Mbps and have downloaded 100 Mb in 8 seconds, Veeam Backup for Microsoft 365 will stop retrieving new data for approximately 2 minutes after which download will be resumed automatically. The exact time for which Veeam Backup for Microsoft 365 stops getting data is calculated by predefined algorithms and depends upon the value that you specify as traffic throttling, the amount of downloaded data and the amount of time it took to get this data.

    1. Click OK.
