My kopia setup is as follows: Arch Linux, Kopia(UI) 0.15.0, rclone to Google Drive. After making the repository, I noticed a new folder in my home dir with the same name as the rclone remote. It has all the files from Kopia (kopia.maintenance/repository/blobcfg.f, and the 3 char directories, etc) and the folder is around the same size as a former failed initial snapshot (34.8GB) but still less than the finished initial snapshot (49.5GB)
What is this folder and can I delete it?
