Langmeier Backup

Langmeier Backup software is designed to help you securely back up your data, especially for small and medium-sized businesses. By following proven backup principles, you can ensure long-term protection and reliable recovery of your valuable information.

One of the most important data backup systems is the implementation of the so-called grandfather-father-son principle.

This data backup strategy—often referred to as the generational principle—involves creating backups in successive stages, much like the family hierarchy of grandfather, father, and son. This approach generates multiple backup versions, allowing you to restore data from previous generations if needed. For example, if data becomes corrupted at the "father" level, you can recover it from the "grandfather" backup. The same logic applies to the "son" level. This method is commonly known as a rotation scheme, where backup media such as tapes are reused according to a defined schedule.

How Langmeier Software GmbH Implements the Backup Process

Three distinct backup groups are established: daily, weekly, and monthly. For a typical five-day workweek, daily backups are performed on new tapes, rotating the so-called "son" tapes. Each tape is overwritten after seven days. At the end of each week, a "father" tape is used, which is only overwritten after a month, following a monthly rotation. Finally, at the end of each month, a "grandfather" tape is created, which is rotated annually—meaning the first tape in this series is only overwritten after a full year.

In practical terms, this means that during a five-day workweek, "son" tapes are used for the first four working days, while a "father" tape is used on the last working day (typically Friday). This "father" tape is created four times a month, and a "grandfather" tape is used on the last day of each month.

This rotation-based backup principle within the grandfather-father-son scheme is the foundation of the data protection strategy we use at Langmeier Software GmbH. Our approach has been refined and professionalized through years of experience. We also utilize incremental backups, which means that only data changed since the last backup is saved. This method significantly reduces both storage space and backup time.

The Advantages of the Grandfather-Father-Son Backup Principle

With this approach, your data is retained for short, medium, and long-term periods, ensuring that you can restore information from a previous backup level at any time in the event of data loss. This provides a robust and reliable safety net for your business-critical data.
