The key to recovery from a Ransomware attack is the boy scout motto "Be Prepared".  In our case, not only did we have backups at the DR site but both the Production site and DR site each had a NAS on a different subnet with different Admin passwords that had backup copies, so 4 total backups. We also were using iSCSI connections to our SAN which the ransomware was not able to cross when they polluted the connection file. This was an unexpected bonus. We were basically back up and running in 4 hours after wiping and restoring files. Lessons learned were to separate as much as possible so if one part of the domain/forest gets corrupted it cannot travel to the other areas. We now use Veeam for Hyper-V windows VMs and Zerto for VMware VMs, another separation of business functions with different admin passwords. Nothing is foolproof but by making it as difficult as possible then makes more time to catch and stop the attack sooner.

I would recommend Veeam.  I have used Veeam Backup and Recovery over the past 5 years and was consolidating Netwoker and NetBackup solutions into a single platform (Veeam).  It was easy to install and configure.  I had multiple VMware ESXi hosts and approximately 300 VMs.  I also Had Physical servers that were either Linux and Windows.  I had also used the Veeam 365 product installed for backing up emails, Teams, OneDrive and SharePoint content.   My goal was that anyone in IT could do recoveries and end users could recover any files they needed to.   I have recovered files, filesystems/drive and parts of or entire VMs with little effort.  It will report to you as much as you want to know and any failures in backups that may have occurred.   I have never worked for Veeam I was just a satisfied user.  It's not without its issues and there did seem to be a bit of a price creep but the backup environment grew and that was most likely the biggest cause.  You can backup to Local, remote disk and to tape and of course to the cloud.  Also as a last note, I never had any issues when providing artifacts for compliance auditing with Veeam.  Best of luck to you.

Ensure when doing backups that the VMs don't have several snapshots already on them as it can hinder the snapshot process from a backup application and also when removing the snapshot with long stun times.  Even using Veeam this can happen as I have seen it first hand.  Other than that most backup applications work.

I have been using Zerto for almost 10 years. It was purchased as a replacement for EMC Recover Point. The product is easy to install and configure. Run books are created to automate the recovery of systems in a timely manner in the event of a disaster. Once installed, it can make disaster recovery testing simple and quick. For testing, an isolated network "bubble" is created and all systems are...

I agree with what you shared. Zerto is a great product and their support is very good. It is disappointing that I have to stop using it because they are discontinuing Hyper-V support. I am looking at other products and options.
