Dell NetWorker 19.9 Administration Guide

Ensure that the environment meets the following requirements to perform Client Direct backups:

• NetWorker clients on UNIX/Linux or Microsoft Windows can perform non-root and cross-platform Client Direct backups to AFTDs. The AFTD can be managed by either a UNIX/Linux or a Windows storage node, and can be either local or mountable on the storage node.

  To perform non-root and cross-platform Client Direct backups to AFTDs, the NetWorker server and the storage node software must be version 8.1 or later.

• If an NFS server provides the AFTD storage for Client Direct backups, then the NFS server must permit access by using the NFSv3 protocol with AUTH_SYS (AUTH_UNIX) authentication. The NFS server also must not restrict access to clients by using only privileged ports.
  NOTE:NetWorker 19.9 supports the NFSv4 v4.1 and v4.2 protocols.

• If you enable checkpoint restart for a client, then Client Direct backups are supported only to AFTDs, and not to DD Boost devices. If a client is enabled for checkpoint restart and a Client Direct backup is tried to a DD Boost device, then the backup reverts to a traditional storage node backup instead.

  For Client Direct backups to AFTDs, checkpoint restart points are made at least 15 seconds apart. Checkpoints are always made after larger files that require more than 15 seconds to back up.

• Archive operations are not currently supported for Client Direct backups.
