    This is a common question over the years in this forum but I have a specific focus. I have read every thread related to tag 'backup'. I've searched the forum, read the manual, and have looked elsewhere for specific answers.

    I need to work out a stategy for recovery of failures with the ISPConfig master server itself. That is, what plan leads to effective save and fast restore of an ISPConfig controller?

    It's easy to sync a secondary system with a primary. When the primary dies, what's the expected plan to bring it back and resync with the secondary?
    I know this isn't right but I'd like to understand why:
    - Install a primary and a secondary
    - Destroy the primary.
    - Go to secondary to continue some operations.
    - Install a new base system. Make this a mirror of the secondary.
    - This makes the secondary now the primary.

    At this point...
    - Adjust IP addresses and hostnames so that the new system is the primary and the fail-over system is again secondary?
    - Adjust hostnames so that the original secondary remains the new primary (NS2>NS1, MAIL2>MAIL1, etc)?

    There are many notes in this forum about how to get backups, but I don't see anything about the correct way to do a restore, other than copying files back and doing a common MySQL restore.

    What is YOUR plan if your master controller goes BOOM?

    Can someone post (link) a complete list of resources that are related to ISPConfig so that we can ensure that we get a good backup and restore? That is, it doesn't matter what each site does, as long as they all accomplish the same goal.

    I've virtualized all my systems, even if there is just one VM on a hardware node, and use snapshot backups for easy backup and restore.
