# Backup destinations that are tested

Test connection is a real probe run by an agent: a write, a read and a delete on a bucket, a write and a free-space check on a folder. A read-only key is correctly reported as failed, and the connection log shows every step.

## Live numbers

Opening the destinations list tests every destination, so what you see is measured now. A folder shows how much your backups take and what is free, a bucket shows its total.
