Planned and unplanned maintenance can require reinstalling the operating system on any individual system, and may also destroy local data. /scratch filesystems are normally undisturbed, but we cannot guarantee this. Important data must not be stored only on server/node local drives.

The HPC Group Team performs daily backups of local drives in HPC servers, but does not keep snapshots or archive older data. Before routine maintenance, we refresh our backups in case of unexpected problems, but this is on a best effort basis.
