Bandwidth

How much bandwidth do I need with WSC?

WSC replicates video surveillance data generated from surveillance cameras stored on a local storage system to Wasabi. This data traverses the Windows machine on which the WSC software is hosted.

To quickly estimate your required internet speed, you can use the “1/5 rule of thumb”:

• If you know the average bitrate of all your cameras:
  Multiply total recording bitrate x 1.5 (allows for read back and fluctuations)
  
  Example: 173 Mbps x 1.5 = ~250 Mbps
• If you know the current storage requirements for a given retention period:

  Multiply #GB / #days x 0.15
  
  Example: 350 GB per day = 350 x 0.15 = ~50Mbps, 100TB per month = 100 x1024 x.15 ÷ 30 = ~500 Mbps

Throttling the Bandwidth Usage of WSC Software

Bandwidth can be set to a limit or scheduled, as long as enough bandwidth is available to upload. Otherwise, WSC will always fall behind, resulting in data loss in situations where all data is not backed up to Wasabi.

The number of threads used to upload data can be reduced, or WSC can be paused during certain hours to avoid replication.

1. Run "regedit" (Registry Editor) on the Windows host machine.
2. Navigate to KEY: HKEY_LOCAL_MACHINE\SOFTWARE\Wasabi\tiger-bridge\tiersvc\settings
3. Look for value: work_threads_count
4. Choose a value between 1 and 16. (A value of 1 will throttle to ~50-100 Mbps upload depending on your system, cloud, and connection. A value of 16 will saturate a one Gbps pipe.)
5. After changing the number, restart the WSC services from the Windows Services app.
