Storage areas, quota, and backup
Home directories
Each user has a home directory /nird/home/<username>
, where
<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:
$ dusage
Home directories on NIRD also contain a backup of Betzy, Fram and Saga home
directories (when relevant) in /nird/home/<username>/backup/fram
and
/nird/home/<username>/backup/saga
.
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.
Scratch directories
The total storage space of /scratch
is 15 TB.
Each user has a scratch directory /scratch/<username>
.
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.
Project area
Each NIRD Data Storage project gets a project area /nird/projects/NSxxxxK
,
where 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
Backup
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.
