Patch and probe cache on remote sites

Patch and probe caches are locations within a customer environment where the probe stores Windows and third‑party patches, installers for N-central features, including new versions of the agent, and the metadata files used by agents.

At remote sites, downloading patches and software updates directly from the central server can consume significant bandwidth and affect network and internet performance. This impact increases when multiple devices require updates, especially in locations with slower or less reliable internet connections.

N-able N-central lets you configure a probe to create a local cache on a remote server. When you grant access, the probe stores downloaded patch updates and agent files on that server.

Devices at the remote site can then download updates from the local cache instead of the central server. This reduces bandwidth usage and improves download times.

To grant access to a site, when adding or editing a probe, select the Grant Access tab, and turn On the toggle in the Caching column for the site.
