Grandfather-Father-Son (GFS) Archiving Explained

Last Updated: Mar 06, 2018 11:47AM CET
Please note this feature is only available for Unlimited, Unlimited Plus and Subscription users.

The Retention Policy has remained the same in 7.6. You can still choose a retention policy (ex. 2 weeks from last successful backup) and any Backup Version older than the retention policy is deleted.

However in V7.6 instead of deleting all old versions, you now have the option to enable GFS Archival  (onsite only) to keep Weekly, Monthly and Yearly Backups beyond your Retention Policy.

Over and above your Retention Policy, with GFS Archiving enabled, Altaro VM Backup will keep:

  • 1 Backup per week for 12 weeks
  • 1 Backup per month for 12 months
  • 1 Backup per year for 2 years

The time periods shown are always calculated from the time of the last successful backup:

Enabling GFS Archiving

In order to enable GFS Archiving, you can do so by navigating to the Retention Policy screen. Please note that this is enabled per policy, so in order to do so, click on the little pencil icon in order to Modify the Policy.

A pop-up window will open, allowing you to select "Archive Old Backups (GFS)" under "Archival Plan for Backups that are older than the set Retention Policy" and then simply click "Modify".

Therefore, we'll be keeping Weekly, Monthly and Yearly Backups beyond the 1-month Retention Policy.
