What is differential backup?

What is differential backup?

  • It is like any other backup ; just a fancy name
  • backup of changes after the last full backup
  • A quick backup
  • backup of changes since last incremental backup 

EXPLANATION

A differential backup backs up only the files that changed since the last full backup. For example, suppose you do a full backup on Sunday. On Monday you back up only the files that changed since Sunday, on Tuesday you back up only the files that changed since Sunday, and so on until the next full backup. The amount of data being backed up grows with each differential backup until the next full back up
