The Difference Between Differential and Incremental Backup Types

If you are in the process of comparing backup systems for your computer data then there are some backup types you should be familiar with. These backup systems include full backups, differential backups and incremental backups. All three of the backup options just mentioned are detailed here and information is also included about how to combine the different backup options for optimal performance.

The first line of action regarding any type of backup plan is to do a full backup of your data. When a full backup is performed, all data that is selected gets backed up and archived. A full back up is very time consuming but it is an essential starting point for any backup plan.

A backup system that backs up only the data that has changed in the time that has passed since the previous backup was done is called a differential backup. As an example, if a full backup of your data was last completed on Wednesday then when the backup starts its process on Thursday it will only back up the data that changed since the full backup that was completed on Wednesday. This type of backup is especially beneficial if you need to completely restore your data since only the latest differential backup is required for the restoration and this cuts back the time substantially.

Another type of back up is called incremental and it differs in that it saves numerous backups of your data. Contrary to a differential backup, an incremental backup does not only save the last one. Each original set of data that is backed up gets stored once. Successive backups are made up of merely the data files that underwent change since the preceding backup will carried out.

If you are planning on using either a differential or an incremental backup system the best suggestion is to choose one of the following choices. You always back up all of your data whether or not any of your data has changed. You do full backups plus incremental backups. This means you do a full backup periodically but do incremental backups regularly. Your last choice is to do full backups periodically together with differential backups regularly. The differential backup system will save all data that changed in the time between the last full back and your current differential backup.

Continuous Data Protection

As has been outlined, the three main backup types are full backups, differential backups and incremental backups. Although it is very time intensive, a full backup is a mandatory function that needs to be carried out. A differential backup is a method that only backs up data that has changed since your last backup. Last is the incremental backup system which preserves several backups of your data. By choosing a combination of these backups as outlined above, you can leverage the benefits of each to create a back up plan to best secure your computer data.
