Backup

This page describes the backups taken on NIRD and the HPC clusters.

Fram

Home directories on the Fram HPC cluster (/cluster/home/$USER) are backed up nightly to user's home directory on NIRD (/nird/home/$USER/backup/fram). $HOME/nobackup and $HOME/tmp directories are excluded from the backup.

The nnXXXXk project directories (/cluster/projects/nnXXXXk) are backed up nightly to NIRD.

The shared areas in /cluster/shared are not backed up to NIRD.

The scratch areas in /cluster/work/jobs and /cluster/work/users do not have any backup.

Saga

Note: Backup on Saga has not been implemented yet, but will be soon!

Home directories on the Saga HPC cluster (/cluster/home/$USER) are backed up nightly to user's home directory on NIRD (/nird/home/$USER/backup/saga). $HOME/nobackup and $HOME/tmp directories are excluded from the backup.

The nn*k project directories (/cluster/projects/nnXXXXk) are backed up nightly to NIRD.

The shared areas in /cluster/shared are not backed up to NIRD.

The scratch areas in /cluster/work/jobs and /cluster/work/users do not have any backup.

NIRD

Both home directories (/nird/home/$USER) and project areas (/nird/projects/NSxxxxK) have backup in the form of snapshots and geo-replication.

Snapshots are taken with the following frequencies:

  • /nird/home/$HOME:
    • daily snapshots for the last 7 days
    • weekly snapshots for the last 6 weeks
    • Note that this also includes snapshots of the Fram and Saga homedir backup
  • /nird/projects/NSxxxxK:
    • daily snapshots for the last 7 days
    • weekly snapshots for the last 6 weeks

List snapshots

Snapshots are available at the following places:

  • /nird/home:
    • /nird/home/u1/.snapshots
  • /nird/projects/NSxxxxK:
    • /nird/projects/NSxxxxK/.snapshots

Restore data

To recover a file

 /nird/projects/NSxxxxK/dataset1/myfile

inadvertently deleted (or to recover an older version) do

cp /nird/projects/NSxxxxK/.snapshots/DATE/dataset1/myfile /nird/projects/NSxxxxK/dataset1/

Select DATE accordingly to your case. Similarly, for a file in the home directory:

cp /nird/home/u1/.snapshots/DATE/$USER/mydir/myfile /nird/home/$USER/mydir/

Note that snapshots are taken every night only. So file created the day of the deletion cannot be recovered with snapshots.
