About enabling network throttling
You can limit the effect of a backup on network performance by enabling network throttling.
Many variables affect the network performance. Consider the following points before you use this feature:
Is your network wired or wireless? What are the speeds of your network cards?
What is the size of your network pipeline? Does it support 10-MB transfer rates, or 1-GB transfer rates?
How robust is your server hardware? How fast is its processor? How much RAM does it have? Is it fast or slow?
How many computers are scheduled to back up at the same time?
Are backups scheduled to run when network traffic is heavy or light?
