## Backup
CERNBox keeps multiple backups of your data. Concretely, backups are kept for the following periods:
- 7 daily backups (so, a snapshot for every day of the last week)
- 5 weekly backups (so, a snapshot for every week for the last five weeks)
- 6 monthly backups (so, a snapshot for every month for the last six months)
- one backup of the last state of your CERNBox when you leave CERN
- 7 daily backups (a snapshot per day for the last seven days where you made modifications)
- 5 weekly backups (a snapshot per week for the last five weeks where you made modifications)
- 6 monthly backups (a snapshot per month for the last six months where you made modifications)
As such, we can restore files only for up to six months. In case you would like to restore something from backup, please reach out to the CERNBox support team via a SNOW ticket.
Note thus that these snapshot do not need to be consecutive: if you modify files on your CERNBox only once per week, we will have seven daily snapshots from seven different weeks.
Upon leaving CERN, we will delete all your old back-ups, and we save one final snapshot that we keep indefinitely.
In case you would like to restore files from your back-up, please [create a SNOW ticket](https://cern.service-now.com/service-portal?id=service_element&name=CERNBox-Service).
