Windows Embedded / Windows IoT OSes are supported (except for custom builds by certain vendors that do not have components required for Veeam Agent operation). Microsoft Failover Clusters are supported for Veeam Agent for Microsoft Windows managed by Veeam Backup & Replication only. To learn more, see the Veeam Agent Management Guide. Veeam Agent operating in the standalone mode does not support Microsoft Failover Clusters. 2 Veeam CBT driver is supported only if Microsoft Windows update KB3033929 is installed on the Veeam Agent computer.
File System	Microsoft Windows FAT32/exFAT, NTFS, ReFS file systems are supported. The supported file system must reside on a volume that is 64 TB or smaller, because Veeam Agent uses the Microsoft Software Shadow Copy Provider to create a volume shadow copy during the backup.

Keep in mind that Veeam Agent cannot work with third-party volume managers installed on the protected computer. Such managers may not allow Veeam Agent to interact with necessary interfaces and services properly.

Backup Target

Backup can be performed to the following types of storage:

Disk-based storage

Local (internal) storage of the protected computer (not recommended).
Direct attached storage (DAS), such as USB, eSATA or Firewire external drives, and raw device mapping (RDM) volumes.

IMPORTANT
