When to start using Mirror Tool
If you have an offline environment, meaning the computers in your network do not connect to the internet for a prolonged period of time (months, a year) the Mirror Tool (available for Windows and Linux) is the only way to distribute product module updates, because it downloads all available Level and Nano updates during each new update request if there is a new update available.

Read this Knowledgebase article to set up Mirror Tool chaining (configure Mirror Tool to download updates from another Mirror Tool). |
The major difference between ESET Bridge (HTTP Proxy) and Mirror Tool is that ESET Bridge (HTTP Proxy) downloads only missing updates (for example, Nano update 3), while Mirror Tool downloads all available Level and Nano updates (or only Level updates, if specified), regardless of which update the specific product module is missing.
|
Streamed updates are not available with Mirror Tool. We recommend to prefer update via ESET Bridge (HTTP Proxy) to update from a mirror wherever possible. Even if a computer is offline but has access to another machine that is connected to the internet and can run ESET Bridge (HTTP Proxy) to cache update files, select this option. |
In the same network of 1,000 computers we tested the Mirror Tool instead of ESET Bridge (HTTP Proxy). The analysis showed there were 5,500 MB of updates downloaded for the month. The size of downloaded updates did not increase by adding more computers to the network. This is still a huge decrease in load compared to a configuration where clients connect directly to the internet, but the improvement in performance is not as substantial as when HTTP Proxy is used.

Even if there were more than 1,000 computers in a network, the bandwidth usage concerning updates would not increase significantly using either ESET Bridge (HTTP Proxy) or Mirror Tool. |
