Local Storage

Transitory Storage

All UNIX machines have local storage available for transitory use. These directories may be used to store temporary, local COPIES of data that is permanently stored elsewhere or as a staging point for output.

These directories may not, under any circumstances, be used as permanent storage for unique, important data. UMIACS staff cannot recover damaged or deleted data from these directories and will not be responsible for data loss if they are misused.

Please note that /tmp in particular is at risk for data loss or corruption as that directory is regularly used by system processes and services for temporary storage.

These directories include:

 - /tmp
 - /scratch0, /scratch1, /scratch*
 - any directory named in whole or in part "tmp", "temp", or "scratch".
