In this video, Keith Barker covers backup types. There are two types of people in the world, those who’ve lost data, and those who have yet to. In the world of protecting data, there are three types: full, incremental and differential — Keith explains the difference.

The three backup types differ in how much of the data in question they capture and store for future restoration.The names of each backup type gives a clue as to how much of the data is captured when it’s performed.

Full backup. A full backup is exactly what it sounds like: everything. A full backup captures all the data, but the downside is that it can take a long time.

Incremental backup. An incremental backup catches only the data that has changed since the last backup. Every time an incremental backup is performed it catches only the changes made since the very last backup.

Differential backups start just like incremental backups: they catch the data that has changed since the last full backup. But then in each repeated incremental backup, all changes since the last full backup are tracked.

Each of these are different in terms of speed and size of the backup itself. Full backups should be done as often as possible, but take a long time. Differential backups are bigger than incrementals, but significantly safer in the event of a backup failure, and also faster to restore.
