Scheduled BackupΒΆ

Context

On HPC systems, there are typically separated scratch filesystem (fast but volatile, say $scr) and archive storage (slow but backed up, say $backup).

Hint

  • rsync
  • crontab
Write a bash script to automatically backup $scr/project_a/ to $backup/project_a/

  1. Prepare rsync script

    sync.sh (need to be made executable)
    #!/bin/bash
rsync -aq $scr/project_a/ $backup/project_a/  # Note: the tailing slashes matter

  2. Set up cron by running crontab -e and adjust the backup time (use absolute path to the sync.sh script)
