About mixed mode volumes

Mixed mode volumes are the volumes having multi-protocol access. Storage array vendors allow both NFS and SMB access to a NAS volume. D-NAS policy allows backup of volumes having multi-protocol access. The protocol used for backup of these volumes depends on the type of backup host pool specified in the policy. If a Linux backup host pool is specified in the policy, these volumes get backed up using NFS protocol. If a Windows backup host pool is specified in the policy, these volumes get backed up using SMB protocol.

This mechanism can be used to backup SMB share data using a Linux backup host. For this to happen, enable NFS and SMB access to the NAS volumes.

Note:

When a Linux backup host is used to backup an SMB share, the backup of SMB ACLs does not happen. Only the SMB share data is backed up.
