Backup Software

We store so much vital data on computers that losing this data could have catastrophic consequences.

Purpose of backup software

  • Backup software creates a copy of important data, so that it can be stored in an external location.
  • Having multiple copies of the data means that if something happens to one of the copies, we can restore it using another.

Full backup

  • A full backup is where a copy is made of everything on the system onto the backup media.
  • Full backups are slow processes and take up a lot of space.
  • It is very easy to restore a system from a full backup.

Incremental backup

  • An incremental backup is where only the files that have changed since the last backup are copied.
  • Incremental backups are faster and use less space.
  • It is more difficult to restore a system from incremental backups because:
    • The most recent full backup must be applied.
    • Every incremental backup since then must then be applied in the correct order.
