rsync -av --delete /home/user/data /backup/location
Add it to your crontab to run daily, ensuring your data is always secure and up to date.
#!/bin/bash
top -b -n1 > /var/log/system_check.log
df -h >> /var/log/system_check.log
echo "System check complete on $(date)" >> /var/log/system_check.log
This script logs real-time system metrics and storage details for later review.
With these examples, you can see how Linux commands for DevOps transform routine tasks into efficient automated processes.
