Unlike Windows, Linux is extremely secured, stable, open sourced and affordable OS. However, Linux servers are vulnerable to few events that can cause data loss. These may not be necessarily an external breach or threat. It could be some normal tech issue caused by electrical fluctuations, hardware issues, fire, and even physical thefts or in some rare cases security attacks too.
What it takes to be a Linux admin expert are the backup practices that he implements to save data on Linux hosted servers. Here are few not-much-discussed Linux backup practices to prevent data loss caused by aforesaid events:
Planned Backup: A proper planning prepares you for the worst that may come your way and saves you from its impact. It applies for Linux servers too. As an experienced Linux administrator you should plan the right backup strategy. Whether it should be incremental or full backup, what data is to be backed up and likewise a proper assessment and planning prevents data loss.
Automation is the key: Keep up the trends to remain afloat in the competitive environment. Make use of automation tools for Linux backups. It enables admins to monitor scheduled backups and quickly restore the entire system in the virtual environment or onto the hardware.
Invest in Backup storage tools: A backup plan becomes infallible when there are right software that can optimize storage by compressing files. Invest in such tools which makes things fast and efficient.
Preventive security measures: If you are sending any backup data over the internet then you must be using strong encryption while transferring the data to save it from online security threats.
Testing your backup: this is a very critical step which many administrators give a miss. All your planning and efforts may go for a toss if you are not testing your backup periodically.
