Autodeletion returning of scratch filesystem

We’re making some important updates to how your project’s temporary data is stored and managed on our HPC platforms. These changes will improve the availability and performance of our scratch filesystem (/nesi/nobackup).

What is changing?¶

Data stored in our scratch filesystem (/nesi/nobackup) that is not touched for 90 days or more will be automatically deleted. This is a change from our previous timeframe of 120 days.
Scans and deletions will now happen on a weekly basis. You will still be provided two weeks notice before any data is deleted.
There will be no exclusions to the 90-day auto-deletion process. If you need to store data for longer than 90 days, get in touch with our Support Team.

When will this happen?¶

This new data management process will launch in late November / early December 2025. Keep an eye on our Status Page (HPC Storage system) for updates.

How will I know if my data is flagged for deletion?¶

Prior to data being deleted, we’ll send you an email that identifies what has been marked for deletion. You can unsubscribe from receiving these notifications through my.nesi You can also manually check at any time if you have any data scheduled for deletion. Instructions for that can be found here.

More information¶

Our Support Documentation has more details on how our auto-deletion cleaner works as well as advice for where to store different types of data on our HPC platform: - Automatic cleaning of nobackup file system - Where should I store my data on NeSI systems?

If you have any questions or would like to discuss your data storage needs in more detail, come to one of our Weekly Online Office Hours or email our Support Team.
