The grand test of restore
• The goal of the test was to ensure the possibility to get all system up
and running in a hosted datacenter, if all server environments, including
the on-premise backup/restore control server was destroyed.
• The test included recreation of the necessary backup servers, the AD,
part of the exchange environment and part of the SQL servers.
• (Folketinget was the first customer demanding a test including
recreation of the backup/restore control server
