If I add an exclusion for an asset in the Cloud. Is that synced back to the scan servers?
Yes, exclusions added in the Lansweeper Cloud are synced back to your on-prem scan servers. When a new exclusion is created or updated in the cloud, it's replicated to the Lansweeper on-prem servers, and the scan servers will use the updated exclusion list to determine which assets to scan. Exclusions created in the cloud are typically applied globally to all scan servers. This means that if an asset is excluded in the cloud, it will be excluded from scans performed by any of your on-prem scan servers, regardless of the scan ranges defined for those servers.
