Why back up UNIX or Linux (or windows) systems?

last updated in Categories News

This is one of main responsibilities of a system administrator. It is his/her job to safeguard data stored on the system. Data is lost by (according to IBM white paper):


  1. Hardware or System Malfunction (44%) such as Hardware equipment failures
  2. Human Error (32%) such as Accidental removal of files
  3. Software Malfunction (14%) such as Software failures or crash or File system corruption
  4. Viruses (7%)
  5. Natural Disasters (3%) such as Fire
  6. Others such as Crackers/Hackers, Unskilled employees or Dissatisfied employees

How much data can you afford to lose?
The cost of recovering data and time both are very high for example:
To recover sales and marketing data 50M data it could take 15+ business days and cost running over USD $15,000+.

Therefore, to minimize the chance of data loss you should do regular backups: Regular backups result into:

  • Minimize data loss
  • Stability
  • Keep your users happy

The exact backup procedure is different for each organization; it depends upon factors such as:

  • Number of users
  • Amount of activity
