LCC storage Quotas

Scratch storage and data protection policy

LCC Scratch storage space (typically located under /scratch) on CCS/ITSRCI systems is short-term storage for active computation, not long-term storage. Files that have not been accessed or modified for 90 days are automatically deleted under the scratch space purge policy.

Deliberately circumventing this policy is prohibited. This includes artificially modifying file timestamps to evade the automated purge mechanism—for example, by running touch or any equivalent manual or scripted method to reset access or modification times. Similarly, making copies and deleting the original to avoid the purge mechanism is not allowed. Such actions constitute misuse or abuse of technology resources under the University of Kentucky Administrative Regulation AR 10:1.

Under AR 10:1-IV.K.(d), violations may result in corrective actions, up to and including suspension or termination of access to technology resources, and disciplinary action. The University may also temporarily suspend or block access to accounts or data while a violation is investigated. Users will receive notice before any sanction is applied.

Important notes

• CCS/ITSRCI does not back up data on behalf of users. You are responsible for keeping backup copies of your data. If a CCS/ITSRCI file system experiences data loss, CCS/ITSRCI is not responsible for recovering your data.

• CCS/ITSRCI automatically deletes unaccessed data under /scratch and /pscratch periodically. If your data is not accessed at least once every 90 days, it will be deleted.

• Attempts to circumvent the 90-day purge policy will result in your account being suspended and investigated, as detailed in University of Kentucky Administrative Regulation 10:1. This includes artificially updating file timestamps in a manual or scripted manner, or copying and deleting files.
