Moving files from a location to another one (such as from internal memory to external SD card) will make GCloud back them up again since the modification date of them will be changed.
To address this, please apply the following:
- Wait until GCloud finishes uploading the files.
- Tap the Restore button.
- Tap the name of your device.
- Browse your backup and go to the old location where those files have been saved before you moved them.
- Once you find the files, select them by simply long-press on them
- Tap the Delete button.
Do not delete anything from the backup this way unless you are 100% sure you do not want the file anymore. The delete action cannot be undone, and the deleted files will not get automatically backed up again unless they are modified.
