Please remember that NO filesystems are backed up, and any files in /scratch that have not been accessed for 21 days or more will be permanently deleted. You are responsible for ensuring you have a copy of any critical data. |

Notes
- There are multiple timestamps for files - last access, last modification, and creation.
- Purging is based on access time. "
ls -l" by default shows modification time.
You should use the "-u" flag to see last access time. "ls -ltu" is recommended. - Some files in a directory may get deleted while others remain. It depends on what was accessed in the last 21 days.
- When copying/rsyncing/untarring files, be sure not to retain original timestamps. Otherwise , otherwise the files might be immediately eligible for purging.
- As Pawsey recommends keeping copies of "long-lived" data within its Acacia object storage system,
please familiarise yourself with some of the know known issues when using the object storage,
as documented in the Acacia - Troubleshooting page.
