The security and storage of your data is something that we take very seriously. Yes, your databases are backed up. Kiwi databases are cloned to a secondary server in real time, ensuring that even in the case of an unexpected catastrophic failure we have a to-the-second copy of the latest data. We also take snapshots of both the database and web files (including user-uploaded files) to disk every night. Furthermore, those snapshots are also backed up to an secondary off-site data-center nightly.
