Significant Linux Backup Practices Helpful For Administrators

Linux is an operating system that is preferred for reliability, security and steadiness. However, like other operating systems, it has issues concerning data protection due to:

Electrical surge
IT data breaches
Failure of hardware
Physical theft
For Linux administrator, it is important to have online backup plan to avoid downtime and loss of important data, money and time.

Planning before Backup
Planning is crucial stage to check various sections of strategy in detail. Ask some questions to find out your requirements for backup plan, such as:

What type of data you need to have backup?
What kind of backup will support your system?
Do you need incremental of full data backup?
How often you need to access to stored data?

Automate Tools
There are backup utilities that need to use command line to perform work. SPX is specifically made for Linux that gives opportunity to administrators to check backup jobs and restore systems to virtual environment or hardware within a few minutes. This automation is helpful in executing management tasks when disaster recovery plan is activated.

Backup Storage Needs Investment
If you have an online backup plan, you will need to revise your strategy for storage. Though backup software can compress all files to increase storage space, storage practices require handling copies of files. If Linux box is connected to NAS appliance or hard drive, you can develop solid foundation.

How to Cover Security Challenges?
While selecting data for online backup, you must keep in mind all of the security threats. For data protection, you may need to have lock-in key. Linux provides Seahorse as encryption tool to manage passwords, create Secure Shell keys, and PGP keys to improve security features.

Protection of Backups
It is counter intuitive to keep backups onsite because disaster can ruin years of hard work in a short time. There are two options available for security perspective:

Remove & Transfer
DVDs and tape are inexpensive and removable media that can be used for backup. Save copies of important data by using local backups. It might be a bit difficult to transfer data and swap out media, however, it gives satisfaction as important files are kept offsite.

Network Transfer
Network transfer is one of the easiest ways for offsite backups when you have given access to a distant server. Time required for transferring process depends on backup size, however, the process is fast and just like uploading files. Recovery time is improved through network transfer as there is no need to find and use physical media.

Backups Assessment
It is suggested to check backup plans and strategies on regular basis in order to avoid catastrophe. Automation is perfect to skip monotonous processes. If there is information that is worthy to save on a tape, disc or server, it definitely needs to be checked up time and again.
