Home Directory
Your home directory is your personal space on Anunna, available on every node in the cluster.
Location and size
Your home directory is at /home/<group>/<username>, also reachable as $HOME, where <group> reflects your affiliation. Each user has a quota of 200 GB — see Quotas.
What to use it for
Home is mounted over NFS from the cluster's active master node, which makes it reliable but slower than the Lustre filesystem. Use it for things that need to be kept safe but are not performance-critical:
- programs and scripts you install for yourself
- configuration files (dotfiles, environment settings)
- small inputs and results you want to keep
Do not run large or I/O-heavy compute jobs directly against your home directory; use Compute Storage for that.
Backups
Home directories are backed up to tape regularly and can be restored from up to roughly a week of history. See Backup Policy for what is and isn't backed up across Anunna.
