Backup type

From incremental backup right through to complete backup

The decisive factor in choosing the type of backup is the degree to which the data changes. A differentiation is made between complete (or full) backup, differential backup and incremental backup, whereby partial backups always require that a complete backup has been performed first.

For the data backup, the data and directories for which the content is to be backed-up are defined. Certain file formats, complete data media or partitions can also be defined for backup.

Complete backup

During a complete backup, all data selected for backup is copied 1:1 to the backup medium.

Differential backup

A differential backup backs-up the data that has been changed since the last complete backup.

Incremental backup

The incremental backup includes the data that has been changed since the last complete backup and the last differential backup.

CDP Continue Data Proteced

CDP is a type of continuous incremental data backup. It protects stored data from the effects of corrupted data, whose manipulation is only identified at a later time (e.g. at the stock exchange). It allows the data to be recovered even if the recovery point (snapshot) cannot be defined in advance.


With deduplication, the data is checked for redundancy and cleaned-up before the data is saved to the backup server (disks, cloud). This allows the data to be compressed at a ratio of 1:12. This process reduces the volume of data and therefore also relieves the pressure on the network.
