Network Settings FAQs

What ports does inSync use for backup and restore?

Be default, inSync uses port 6061 for responding to backup requests. For web-enabled restores via HTTPS, inSync uses port 443.

Can I change the ports that inSync uses?

Yes, you can. To know how this is done, see Changing the inSync server ports.

Which protocol does inSync support?

By default, inSync supports communication via HTTP. However, you can configure your inSync setup to enable communication via HTTPS. To know how to do this, see Enabling communication via HTTPS

Can I determine the Quality of Service of the inSync traffic?

We do not perform Quality of Service (QoS) tests. However, you can use third-party tools to determine the QoS of your inSync traffic.

Which type of proxy does inSync support?

inSync only supports forward proxy servers.

Does inSync support PAC files?

Yes, it does. To see how inSync client is configured to recognize a proxy server using PAC files, see Configuring proxy settings using PAC files

Does inSync support WPAD?

Yes, it does. To see how inSync client is configured to recognize a proxy server using WPAD, see Configuring proxy settings using WPAD.

How much bandwidth do I need to back up user data? 

The bandwidth requirements depend on how large your inSync setup is. Generally, inSync clients require a minimum bandwidth of 16 Kbps and 64 Kbps to ensure backups over WAN and LAN respectively. If your bandwidth falls to a value lower than 16 Kbps or 64 Kbps, backups will fail.

As a good practice, you must ensure that the throughput be a value that is equivalent to the aggregate of write speeds for all backups. We recommend the latency to be a multiple of 10, but not exceeding 100 ms.

How can I throttle bandwidth for restores?

We do not support throttling of bandwidth for restores out-of-the-box. However, the Druva Support team can assist you to throttle restore bandwidth. Contact them at
