Backup process doesn't work anymore, stuck a locking the repository

For me Google Drive always returns errors but it always finish. It takes a lot of time, but it is because of Google limitations. Have you tried to unlock the repository to see if that works? You could try restic -r rclone:zombie: unlock and then try again. Here are other posts related to Google Drive errors:
