  • By definition a disaster recovery solution needs to be geographically separate. You’re protecting yourself from catastrophe, and some of those scenarios include your main location burning down, flooding, being hit by a tornado, etc etc.

    So you either need to collocate systems with a friend who you trust, purchase colocation services from a provider, or use a cloud service to achieve what you’re looking for to truly have a DR solution.

    As far as how to do that, the main idea is to have that point in time available on a system that, even if you get compromised, the backups won’t. The old school method here is to use an external hard drive or a tape device, and physically store that offsite. So like use your regular backup mechanism, and in addition to what it’s doing now schedule a daily/weekly/monthly job that backs up to this other device, and then store that away from your main location.

    That’s essentially the idea though, and there are any number of solutions you can use to do it.

    The real issue here is backups vs disaster recovery.

    Backups can live on the same network. Backups are there for the day to day things that can go wrong. A server disk is corrupted, a user accidentally deletes a file, those kinds of things.

    Disaster recovery is what happens when your primary platform is unavailable.

    Your cloud provider getting taken down is a disaster recovery situation. The entire thing is unavailable. At this point you’re accepting data loss and starting to spin up in your disaster recovery location.

    The fact they were hit by crypto is irrelevant. It could have been an earthquake, flooding, terrorist attack, or anything, but your primary data center was destroyed.

    Backups are not meant for that scenario. What you’re looking for is disaster recovery.
