If you have accidentally deleted, corrupted, or overwritten a file on a SENS system, fill out the following form to file a request to have it restored.
For information on backup policies and retention periods, and when your file will be restored, please read the section entitled "Policies for SENS Data Backups" in the SENS Computing Policies and Practices web page.
Please don't use this service as a safety net. File restores are pretty reliable, but things do go wrong from time to time.
