Im currently 1. Duncan has managed to keep things exciting even though he hasnt even gotten to the first beheading. Each season is structured and styled like an accessible history book, with no prerequisites beyond the most basic grade school grasp of history. Terms are explained, historical figures introduced and glossed, context provided. Duncan delivers his text with a bit of vlogger John Greens friendly teacher lilt. He adds the slightest editorializations, sometimes just with a tone of voice or word choice, that humanize the drier parts of bickering parliamentarians and royal decrees. He comes across like a wry bespectacled tutor, reading to his student next to the fireplace in a country palace. Duncan leads occasional tours of revolutionary sites, which are announced on the podcast. He previously created the 1. The History of Rome, which inspired his upcoming book The Storm Before the Storm The Beginning of the End of the Roman Republic.

Several options exist that allow customers to deploy Eyeglass in several configurations. Warm Standby. This procedure is to protect the production Eyeglass appliance. Using the Eyeglass Automated 7 Day Backup feature and Sync. IQ, the procedure will sync the backup archives to a running Warm Standby Eyeglass appliance in a 2nd cluster. Notes on this solution This process also means only One Eyeglass appliance has clusters added. This only requires one set of license keys license keys are appliance specificRequires Sync. IQ enabled clusters to protect the archives. Production Eyeglass syncs Export used for DR of Eyeglass configuration data. The following link provides detailed information on how to set up the Warm Standby Backup Procedure Warm StandbyActive Active This procedure is to protect the production Eyeglass appliance using a 2nd licensed Eyeglass appliance. This solution offers same time sync of DR data to a second appliance that can take over operations under the following conditions Controlled failover switching the active appliance from one data center to the other. Uncontrolled failover protection the 2nd appliance can be used for failover operations since it has a current near real time synced status and copy of all policies and configuration data shares, exports and quotas needed to complete a failover to the surviving cluster. Definitions Active Sync Appliance Responsible for syncing configuration data and is the primary appliance for all failover operations. Active Monitoring Appliance Responsible for inventory of configuration data needed for syncing, monitors sync. IQ, collects sync. IQ job reports. Notes This process means Two Eyeglass appliance have clusters added. This requires two sets of license keys license keys are appliance specificOne appliance has active sync jobs and the other has disabled policies but fully synced view of both clusters.
