Each user has a home directory
<username> is the username. The default quota for home directories
is 20 GiB and 100 000 files. To check the disk usage and quotas, type:
Home directories on NIRD also contain a backup of Betzy, Fram and Saga home
directories (when relevant) in
To account for this default quota is doubled when relevant.
Note that this is a backup from the HPC cluster; you cannot transfer
files to the cluster by putting them here.
The total storage space of
/scratch is 15 TB.
Each user has a scratch directory
The area is meant as a temporary scratch area. This area is not backed up.
When file system usage reaches 75%, files are subject to automatic deletion.
There is no quota in the scratch area.
Each NIRD Data Storage project gets a project area
NSxxxxK is the ID of the project.
The project area has a quota on disk space and the number of files, and you can see the quota and the current usage by running:
$ dusage -p NSxxxxK
In addition to geo-replication NIRD supports snapshots of project areas and home directories allowing for recovery of deleted data. For more information, visit the page Backup on Betzy, Fram, Saga and NIRD.
