New page

* Home directories (/home) are backup up daily with a 14-day retention period for file versions.
** You can thus possibly ask the system administrator to restore a copy that existed in the previous 14 days.
* Lustre data directories (/lustre/users) are replicated every evening. Multiple versions of files are not retained.
** Deleted files are purged on Sundays. This means that if you accidentally delete a file, the system administrator may possibly be able to restore the file if you alert him before the subsequent Sunday.
** If you overwrite a file, it will be replicated around 20:00 that day. If you alert the system administrator before then, he may possibly be able to restore the copy from the previous day.
* Please contact the system administrator (johann.swart at up.ac.za) if restores are needed.
