If you want to explain the topic of backup, terms such as full backup, incremental and differential data backup come up. We reveal what the backup methods can do.

Your way to a successful backup
The importance of data backup will become clear to you at the latest when you lose important or personal data and have not previously taken care of a backup. Accordingly, we recommend that you always create such a backup for your most valuable data.
Most backup solutions provide you with three methods for doing this: the complete
Everything you need to know about data backup
With a backup or a data backup you can protect your pictures, documents and other important files with a backup copy. Netzwelt reveals in the ultimate backup guide how to create a data backup for Windows, OS X, Android and iOS.
Backup Guide: Which Method is Right for You?
With three different backup questions, you might be asking yourself a few questions: Does it even matter which method I choose? What are the differences? Which method is suitable for what? We’ll go through all three backup strategies in turn.
The full backup With the full backup you create a daily system backup with increasing memory requirements. (Source: Netzwelt)
The full backup is not only the simplest type of data backup, but also the most effective backup method. With a full backup, you save all the data on your computer. If necessary, you can restore your system from a file afterwards.
- Advantage: A simple backup and restore with just one backup file.
- Disadvantage: Time-consuming backup process with a very high storage requirement.
The differential backup After the full backup, the differential backups (purple) require more and more storage space over time. (Source: Netzwelt)
With the differential data backup, you first create a full backup and then – about once a week – a partial backup. In the partial backup, only the data that has been changed or created since the last backup is backed up.
The differential backups are getting larger and more extensive day by day, since with each differential data backup the data (already backed up in a previous differential data backup) is saved again.
- Advantage: The differential backup requires more storage space, but can be performed much faster than a full backup.
- Disadvantage: Files that have only been changed once after the full backup are backed up again with each differential backup.
The incremental backup Essential for incremental data backup: The data sets are all linked to one another. (Source: Netzwelt)
Incremental backup is similar to differential backup, with one key difference. Although the incremental backup is also preceded by a full backup, only the data that has been created or changed since the last incremental backup is backed up with each backup.
This means that the individual data sets are all linked and to restore your data you need the first full backup and all subsequent incremental backups.
- Advantage: Incremental backups have a small storage requirement and can be made quickly.
- Disadvantage: The full backup including all incremental backups is required for the restore.
Basically, you always start with a full backup. This is then followed by either an incremental or differential backup. On the next page we will look at another principle and explain in our conclusion what you have to consider for your data backup.
