You can easily check if your backup is running by logging in to Keepit and checking the status under Last Update to the right of your connector.

You can also move the mouse pointer over the status to display the time the last snapshot and the last check were made.

If a backup is currently in progress, you can hover over the status to see the percentage progress as well as how many megabytes were backed up in the last 24 hours. Keep in mind that it will show a negative number if the user reduces the size of the backup dataset.
