The HPC Cloud is a form of Infrastructure as a Service (IaaS), which means that the user must perform administrative tasks on her virtual machines or cluster. This includes the responsibility of taking care of backups. !VirDir can be used to help with backups. !VirDirs allow users to save their data outside their image and provide the option of a backup by SURFsara (by using the backup directory). Backups are made incrementally on a nightly basis. We can restore files and/or directories when you accidentally remove them (provided they already existed during the last successful backup). The retention period for recovering deleted files is 30 days. Every day, the content of your /Backup directory will be backed up by SARA. The /Scratch directory will never be backed up. You are the best person to judge what data should or should not be backed up and we ask you to use your best judgement.''
