We use Zerto to enable our hot site configuration. We have two data centers. One of them is in one of our corporate buildings, which is our primary, and then we have a co-location center rack that we rent for our hot site backup or app. We use Zerto to replicate our servers and our VMs between those two sites. So, primarily, it is there in case of a disaster or malware attack, etc.
We also use it to restore files on the fly for users if they accidentally delete the wrong file or something like that. From a restoration standpoint, it is closer to the frontline of our security posture. We would first look to restore items. For removing the threat and everything like that, it obviously wouldn't be involved, but from a restoration standpoint, it would be frontline.
We have not yet used the cloud with Zerto. We just use on-prem physical servers.
