110 - Ist Archivierung das gleiche wie Backup?

No, archiving is not the same as backup.

Definition of a Backup:
Regular copying of files to a dedicated storage system (backup system) to protect against data loss in the event of a hardware, system or operator failure on the primary or source system (e.g. server, workstation, etc.).

Definition of an Archive:
Copying selected files to a dedicated storage system (archive system) to keep them safe for a longer period of time. The original files can be deleted from the primary or source system after archiving to provide free storage space.

Difference between backup and archive

The fundamental difference between backup and archive is versioning:

• Backup uses versioning

• Archive does not use versioning

This means that if you make two backups of a file with the same name and the same path, in the case of archives these become two independent objects, in the case of backups two versions of an object.
The retention rules for archives and backups are therefore structured differently and lead to the typical application patterns for the respective backup procedure:

• Backup: Data is stored temporarily (usually in several versions) on another medium for security purposes. Backup data is restored in the event of data loss, for example.

• Archiving: The data should be stored securely for the long term. Archived data is normally accessed again.
