Ignition disaster recovery test in a sandbox, without attaching in production


My question is related to Disaster recovery planning exercice for servers running Ignition.
Is there a way to test if the environnement (Server with Ignition installed and backuped as VM snapshot, etc.) is fully working and having it tested in to a sandbox without having it attached to production environnement?
(I’m new to this forum. I try to follow good pratcices, -Please let me know if there is anything).

Many thanks for your help
