Warning!

Puhti and Mahti will be decommissioned after Roihu becomes available. Users should clean up unnecessary files and move any required data by the end of August 2026. See the Roihu data preparation instructions for details.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

Is Pouta backed up?

User data is not backed up. It's the user's responsibility to make backups of data as needed. Depending on the type and amount of data, users can consider making another copy at, or using in parallel, one of the other CSC data services. Please have a look at the Data section.
