Different Types of Data Backup

The different types of data backup are

Full backup

It is a full copy of the entire dataset. Performed periodically.


  • Provide the best (complete) protection
  • Instant access to data – no restoration and rebuilding processes necessary


  • Time-consuming to backup
  • Expensive – require additional resources

Incremental backup

An incremental backup only backs up the data that has changed since the previous backup. The previous backup can be a full, incremental, or a differential backup.


  • Decreases the time taken to backup (as compared to a full backup)


  • Time-consuming to restore and rebuild the data to make it a complete and current

Differential backup

A differential backup is similar to an incremental backup in that it starts with a full backup, and subsequent backups only contain data that has changed. The difference is that while an incremental backup only includes the data that has changed since the previous backup, a differential backup contains all of the data that has changed since the last full backup.


  • Takes less time than a full-backup
  • Takes less time to restore data, as compared to an incremental back-up


  • More expensive than an incremental data, as with time the amount of data being backed-up grows
