Langmeier Backup FAQ

Back up Windows system folders correctly

Windows system folders are unique in that they often contain files that are completely protected from access. As a result, even the most advanced data backup software cannot back up this data. In most cases, these are runtime files—temporary files used exclusively by the Windows kernel or third-party applications during active processes. You can safely exclude such files from your backup routine; there is no risk of losing important information.

The following Windows system folders are particularly relevant:

  • C:/Users/xxxxx/AppData: This folder typically contains program runtime files and master data, including databases and configuration files specific to individual users.
  • C:/ProgramData: Similar to AppData, but stores data for all Windows users on the system.
  • C:/Windows: This directory includes various program APIs (interfaces for applications), modules, and components such as DLL and OCX files. It also contains temporary files generated by the system.
