# Data & storage Source: https://docs.infraista.com/en/data-storage Infraista runs four kinds of data services for you. Pick by how your app or backup tool talks to its data: | Service | Use it for | You connect with | | ------------------------------------------------- | ----------------------------------------------------------------- | ------------------------------------------------ | | [Databases](/en/data-storage/databases) | Your app's relational data | PostgreSQL, MySQL or MariaDB clients and drivers | | [Redis](/en/data-storage/redis) | Caches, sessions, rate limits, locks | Any Redis client, over TLS | | [Object Storage](/en/data-storage/object-storage) | Files your apps serve or store: uploads, assets, renders, exports | The S3 API (AWS CLI, SDKs, rclone) | | [Backup Storage](/en/data-storage/backup-storage) | Backups from your servers, offices and laptops | SFTP, rsync, BorgBackup, restic, WebDAV, FTP | **Object Storage or Backup Storage?** Object Storage is for apps: buckets over the S3 API, public URLs, billed by what you store. Backup Storage is a fixed-size box you mount like a drive and fill with backup tools, for a flat monthly price with no traffic fees.
