I have an Opus backup file MyBackup.ocb which includes an Images folder containing 3 image files. My current configuration in /dopusdata includes an Images folder with dozens of images. According to the description in the Help file...
Prefs RESTORE=replace,all FROM MyBackup.ocb
Replaces your existing configuration completely (corresponds to the similarly named option in the wizard). If you select this, your existing configuration is deleted before the restore is done.
On checking /dopusdata after executing a replacement restore, the images folder still contains dozens of images, rather than the expected 3. I have also tried an explicit Prefs RESTORE=replace,images,sounds,data,localstate with the same result. Clearly, images are being merged rather than replaced.
