Why did we backup E? Remember a differential backup picks up everything that changed since the full backup. When you run the backup on Day 3, it’ll backup 3 files (B2, C1, and E) and it’ll take you 30 mins.File C also changes to C1 and File D gets deleted. One Day 3, let’s say File B changes again and becomes B2.When you run the backup on Day 2, it’ll backup just the 2 changed files and the backup will take you 20mins.

On Day 2, let’s say File B changes to B1, and a new File called E is added.

And let’s say each of them is about 1GB each and each of them takes 10 mins to backup Let’s take the same example – say you have 4 files A, B, C, and D. Differential backup makes a copy of files that have changed since the full backup. The next optimization the industry made was a differential backup.

40 minutes – 50 minutes each day as in our example. When you run the backup on Day 3, it’ll backup 4 files again (D is removed – remember?) and it’ll take you 40 mins.įull backups, as you can see take time.File C also changes to C1, and File D gets deleted. hen you run the backup on Day 2, it’ll backup all 5 files and it’ll take you 50mins.On Day 1 – you’ll backup 4GB and it’ll take you 40 mins.And let’s say each of them is about 1GB each and each of them takes 10 mins to backup. Let’s take an example – say you have 4 files A, B, C, and D. If you perform a full backup once a day – then everything is copied over once a day.

So, all files, objects, bytes however you wish to measure your data – every one of them is copied over to a secondary storage target each time. Full backup essentially makes a backup of everything you wish to protect every time. They are the simplest form of backup and the easiest to understand. I am quite sure everybody who’s reading this blog has heard of full backups. Let’s take a look at each types of backup and its respective pros and cons. There are mainly three types of backup are there: Full backup, differential backup, and incremental backup.
