How To Wakeup Backup Nas Server and Mirror Files Using Rsync in Linux

by

To wake up a backup NAS server and mirror files using Rsync in Linux, you can use the following steps:

  1. Ensure that the backup NAS server is set up to be awakened by Wake-on-LAN (WOL) packets. This can be done in the BIOS or network settings of the backup NAS server.
  2. On the Linux machine, install the “etherwake” utility to send WOL packets. This can be done by running the following command:
sudo apt-get install etherwake
  1. Determine the MAC address of the backup NAS server. You can do this by logging into the backup NAS server’s web interface, or by using the “arp” command on the Linux machine to display the ARP cache.
  2. Send a WOL packet to the backup NAS server by running the following command, replacing “xx:xx:xx:xx:xx:xx” with the MAC address of the backup NAS server:
sudo etherwake xx:xx:xx:xx:xx:xx
  1. Wait for the backup NAS server to start and become accessible on the network.
  2. Run the Rsync command to mirror the files from the source directory to the backup NAS server. For example:
rsync -avz --delete /path/to/source/directory/ backupnas:/path/to/destination/directory/

This will sync the files in the source directory with the destination directory on the backup NAS server, removing any files in the destination directory that no longer exist in the source directory.
