Versions

Each time you save a file in CERNBox, the previous version is preserved so you can easily download or restore it later.

Trash bin

All files deleted from your personal space will land on the Trash bin and stay there for 4 weeks. Admins of a project can also see the trashbin of their project spaces, as described in Projects.

Backup

CERNBox keeps multiple backups of your data. Concretely, backups are kept for the following periods:

• 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)

Note

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 open a SNOW ticket.
