Enabling network throttling

Similar to computer performance adjustments, you can also limit the impact of a backup on network performance.

Network performance is affected by many variables. Consider the following issues before you use this feature:

  • Network cards: Is your network wired or wireless? What are the speeds of your network cards?

  • Network backbone: What is the size of your network pipeline? Does it support 10 MB transfer rates, or 1 GB transfer rates?

  • Network server: How robust is your server hardware? How fast is its processor? How much RAM does it have? Is it fast or slow?

  • Backing up: How many computers are scheduled to back up at the same time?

  • Network traffic: Are backups scheduled to run when network traffic is heavy or light?

Consider using this feature only when you know what your network can handle. If you schedule your backups at staggered intervals and when network traffic is low, you may not need to use this feature. Avoid backing up multiple computers at the same time and to the same network destination.

Gather the required information about your network's performance and then schedule backups accordingly. Then, if necessary, enable this feature and set the Maximum network throughput to a setting that matches the circumstances.

To enable network throttling

  1. In Backup Exec System Recovery, on the menu bar, click Tasks > Options.

  2. Click Performance.

  3. Select Enable network throttling.

  4. In the Maximum network throttling field, enter the maximum amount (in KB) of network throughput that Backup Exec System Recovery can send per second.

  5. Click OK.
