Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

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.
