firewall A system designed to prevent unauthorized access to
or from a private network. All messages entering or
leaving the intranet pass through the firewall, which
examines each message and blocks those that do not
meet the specified security criteria. There are several
types of firewall techniques. The NetWorker software
supports client backups from computers that are
protected by packet filtering.
fork A subprocess the NetWorker software creates to
perform a requested operation. In instances where a
command uses a parallelism value, NetWorker
software creates multiple instances of that command.
Each instance of the command is identical to the
original command and is referred to as a subprocess.
Once each subprocess is created, they are run
simultaneously.
