      Technical operating description

      Operating concept

      • All systems are operated as virtual machines in virtualization clusters.
      • Resources (RAM, CPU, storage and IO) are allocated according to actual requirements.
      • The data storage of the production systems takes place centrally in a clustered RDBMS (2-node multi-master replication with node-local data storage). In addition, replication takes place on a separate third system, which is also used for data backup.

      Data backup and restore

      A distinction is made between the backup of databases and the backup of operating systems.

      • The databases are replicated online semi-synchronously in parallel at two different locations.
      • The databases are exported to a backup file once a day.
      • The configuration files of the Scope application servers are backed up independently of each other on a daily basis and this backup is replicated to another location.
      • The application servers are not backed up completely, as reinstalling the operating system takes significantly less time than restoring the operating system from a data backup.
      • The primary backup takes place on hard disk storage system.
      • The holding time of the primary fuses is 14 days.
      • An additional tape backup of the primary backup files is made.
