I found that a backup has been trying to send to google driver for about a week. It was continually retrying and using system resources as well as bandwidth.
I had to delete the snapshot to prevent it from retrying. Even if I hit the abort it would continue to retry. I tested with Dropbox and it would not upload to their site either.
At this point snapshot is pretty much useless as I don't trust it to run automatically and don't have the time to watch the uploads and stop them if unsuccessful.
I have enabled support access on our site blog.teknorc.com.
Also, I would like to request the feature to abort the upload while it is waiting to retry. There is approximately four minutes while the process waits before uploading again.
Attached is a log file from a failed upload.
