Micro Focus OES
File-level restore is supported for Micro Focus Open Enterprise Server (Micro Focus OES). Micro Focus NetWare is not supported (Veeam Backup & Replication may fail to detect NSS volumes).
AD-enabled NSS volumes on Open Enterprise Server 2015 are supported. Restore of NSS file/folder permissions is not supported.
The FLR appliance uses module ZFSonLinux version 0.6.3. For this reason, Veeam Backup & Replication supports only those versions of pools and features that are available in ZFSonLinux version 0.6.3.
You cannot restore pipes and other file system objects. File-level restore supports recovery of files and folders only.
The multi-OS wizard works not only with basic disks, but also Linux LVM (Logical Volume Manager) and ZFS pools. Encrypted LVM volumes are not supported.
VM Guest OS Files Exclusion
Veeam Backup & Replication supports both basic and dynamic disks. Volumes on the dynamic disks must not be split — spanned, striped and other types of split volumes are not supported.
