The files older than 28 days are clened regularily. For users from other universities, the quota on ``$VSC_HOME`` and ``$VSC_DATA`` will be determined by the local policy of your home institution as these file systems are mounted from there. The path names will be similar with trivial modifications based on your home institution and VSC account number. +--------------------------+------------------------------+ |Variable |Name | +==========================+==============================+ |$VSC_HOME |/user/leuven/30X/vsc30XYZ | +--------------------------+------------------------------+ |$VSC_DATA |/data/leuven/30X/vsc30XYZ | +--------------------------+------------------------------+ |$VSC_SCRATCH |/scratch/leuven/30X/vsc30XYZ | |$VSC_SCRATCH_SITE | | +--------------------------+------------------------------+ |$VSC_SCRATCH_NODE |/local_scratch | +--------------------------+------------------------------+ The ``$VSC_HOME`` and ``$VSC_DATA`` file systems have snapshots, so it is possible to recover data that was accidentally deleted or modified. You can retrieve data by :ref:`restoring a snapshot `. On genius, a BeeGFS file system can be created during the run of a job, for details, see the page on :ref:`using BeeGFS ` for details.
