Differential backup: smaller backup image file & faster and safer recovery process

A differential backup is a backup of every file on a file system which has changed since the last full backup.

Why we need differential backup?

Differential backup is a moderate choice among all backup methods.

  • Comparing to full backup, differential backup takes less backup time and produces smaller image file because it only backs up changed files since last full backup.
  • Comparing to incremental backup, it has a shorter recovery process which only involves the last full backup file and certain one differential backup file you need.
  • Differential backup is safer to recover than incremental backup.
