 - **Bind mount write**: `atomicWriteFile()` now falls back to direct write when rename fails (fixes "device or resource busy" on Docker bind-mounted `controller.yaml`)
 - **Drive mounting after restore**: Restore flow now calls `MountDrivesFromLayout()` to mount drives by UUID and add fstab entries — previously drives referenced in the infra backup were not mounted, causing "Adattároló nem elérhető" warnings
 - **Post-restore redirect**: UI now polls until the controller is actually up instead of using a fixed 5-second timeout (which was too short for container restart)
+- **FileBrowser DB reset scoped to restore**: `SyncFileBrowserMounts()` no longer resets the FileBrowser database volume on source changes — only the post-restore startup path (`SyncFileBrowserMountsReset`) does, preserving user accounts, permissions, and share links during normal storage operations
 
 ### v0.31.6 — UI: Brand-consistent button & card styling (2026-02-25)
