Installing Zerto Virtual Replication : Considerations - AWS with Zerto Virtual Replication
  
Considerations - AWS with Zerto Virtual Replication
Review the following considerations:
The following restriction applies to recovering individual files and folders, and not to recovering the whole virtual machine:
The operating system of the machine on which the recovery site Zerto Virtual Manager is installed determines the types of file systems from which individual files and folders can be recovered.
When the Zerto Cloud Appliance virtual machine operating system supports a file system, files and folders can be recovered from this file system in virtual machines that this Zerto Cloud Appliance will manage the recovery of.
For example, if a protected virtual machine running Windows 2012 has files using the ReFS file system and requires one or more of these files to be recovered and the Zerto Cloud Appliance is on a machine with Windows 2008, which does not support ReFS, the protected virtual machine files and folders cannot be recovered, but the whole virtual machine can be recovered.
