Oracle Linux – Using GNU Parallel command to improve backup(s) to an NFS Server

edited Oct 8, 2025 7:13AM in Linux

APPLIES TO

Oracle Cloud Infrastructure - Version N/A and later
Oracle Linux 7/8/9

GOAL

Improve network throughput and reduce times to backup important data/information to a NFS Server

SOLUTION

cp and rsync commands are used to copy files between filesystem, the use of an additional command (parallel) can help us to copy multiple files at the same time, we do not need to wait for a file to be fully copied to start copying a diff one.
This allows to have a better use of the network.

Make sure backups or copy of large amount of files is done when the usage of the system is low ; preferably after working hours or during the weekend as the parallel command will use all available CPU(s) by default.
