Slow Backup Copy over High Latency, High Bandwidth WAN

Post by chrishahn » Oct 16, 2017 4:27 pm

Attempting to send backup copy jobs to a new DR site. There is 100mbps connection on both sides using point to point VPN. Latency between sites is 70ms. We are only getting 300KB/s - 1.2MB/s copy speeds, and the speed often fluctuates.

Would the WAN acceleration feature help here, or is that only really for low bandwidth connections?

Are there any other tweaks / adjustments needed due to the high latency between the sites to improve the performance?

Hi Chris, what are the bottleneck stats for this job?

The Network is always the bottleneck.

Load: Source 1% > Proxy 4% > Network 99% > Target 0%

In this case I'd definitely try WAN acceleration.
