Storage
Where services keep their data.
| Storage | Built on | Used for |
|---|---|---|
| Volumes | Longhorn | Files of Docker services, PostgreSQL disks |
| S3 buckets | RustFS | Project buckets, database backups, static site files |
How many copies of a volume are kept, and on which disks and servers, is set by its storage profile.
Longhorn does not flush the disk cache on fsync. Production data needs
disks with power-loss protection or a battery-backed controller.
