Error -1020 Sharing Violation and "Error -1111 Locked Range Conflict"

Retrospect uses VSS (Volume Shadow Copy Service) which is built into Windows to copy open files. On Windows, Retrospect uses the ROFF.sys filter driver.

Check the Retrospect License Manager (Configure>Licenses) to make sure you have the Open File Backup Add-On in your copy of Retrospect. If you don’t have the Open File Backup add-on, make sure you close all program prior to the backup.
