Data Restore in Direct NFS Access Mode

In this article

    The Direct NFS access transport mode can be used to restore VMs with thick and thin disks.

    Data restore in the Direct NFS access transport mode is performed in the following way:

    1. The backup proxy retrieves data blocks from the backup repository or a datastore in the target site.
    2. The backup proxy sends a request to the ESXi host to restore data to an NFS datastore.
    3. The ESXi host allocates space on the NFS datastore.
    4. Data blocks obtained from the backup proxy are written to the NFS datastore over LAN.

    Data Restore in Direct NFS Access Mode 

    With the selected option Same as source from the Restore disk type drop-down list, Veeam Backup & Replication restores the disk with the same type as in the backup. However, during the restore in the Direct NFS access mode, the disk type can be affected by settings specified for your NFS server, VAAI, etc. Thin disks can be restored as thin disks, thick eager disks as thick eager disks. Thus, Veeam Backup & Replication converts thick lazy zeroed disks to thick eager disks, if you use VAAI, otherwise to thin disks. For more information about disk types, see VMware Docs.
