Configuring number of threads for backup hosts
To enhance to the backup performance, you can configure the number of threads (streams) that each backup host can allow. You can improve the backup performance either by adding more number of backup hosts or by increasing the number of threads per backup host.
To decide the number threads consider the following:
The default value is 4.
You can set minimum 1 and maximum 32 threads for each backup host.
Each backup host can have different number of threads configured.
When you configure the number of threads, consider the number of cores that are available and the number of cores you want to use. As a best practice, you should configure 1 thread per core. For example, if 8 cores are available and you want to use 4 cores, configure 4 threads.
