Edouard Vanbelle 34a2607658 fix(storage): a read failure is not proof the blob is gone
Ed's point, and the most dangerous bug in the batch: NotFound is a
conclusion callers ACT on. Every read path in all three backends
returned it unconditionally.

    // s3, azure, local — all of them
    .map_err(|e| DomainError::new(ErrorKind::NotFound, …))

So a refused connection, a 503, an expired credential, a stale NFS
handle and an unmounted iSCSI target all reported "blob missing". Nine
sites: get / get-range / stat on each backend.

## Why it is disastrous rather than untidy

`backend_migration` probes its source before copying. A transient probe
error used to `continue` — skip the row, record NOTHING, and let the
cursor advance past it at the end of the batch. With `failed` still 0
the run reached `finish_completed` and FLIPPED THE POINTER to a target
missing every blob the outage covered. A migration reporting success
having silently dropped whatever was unreachable at the time.

That path now pauses when the probe error is transient, and records a
finding when it is permanent, so a run can no longer report clean while
having skipped rows.

## Local storage is not exempt

Ed again: a local backend is a PATH, and that path may be an iSCSI or
NVMe-oF LUN, an NFS mount, or a disk with a failing sector. It matters
MORE there than for a remote backend, because `RetryBlobBackend` is only
applied when the active backend is not Local — nothing below retries, so
the classification is the only thing between a flaky mount and a run
concluding the data is gone.

`local_io_error` maps the network-mount family (TimedOut,
HostUnreachable, NetworkDown, ConnectionReset, StaleNetworkFileHandle)
plus Interrupted and ResourceBusy to transient. PermissionDenied,
ReadOnlyFilesystem and StorageFull stay permanent because retrying
changes nothing without an operator, and InvalidData stays permanent
because corruption is a finding worth keeping. A bad sector arrives as
an uncategorised EIO and lands there too, which is right: the useful
outcome is a finding naming the blob, not a run that waits for a disk to
heal.

## Shape of the fix

Only a genuine absence is NotFound — `NoSuchKey` on S3 GET,
`is_not_found` on S3 HEAD, HTTP 404 on Azure, `ErrorKind::NotFound` on
local. Everything else goes through the classifier, so a 403 stays
permanent rather than being retried forever.

Tested at the local layer, which is where the mapping table is dense
enough to get wrong.

Why People Try OxiCloud

OxiCloud is aimed at self-hosters, home labs, and small teams who want the useful parts of a cloud suite without the operational drag of a traditional PHP stack.

What pulls people in:

  • Standard protocols first: WebDAV, CalDAV, and CardDAV are built in
  • Useful product surface already there: files, previews, sharing, trash, search, favorites, and recent items
  • Modern auth and admin basics: OIDC/SSO, quotas, roles, and shared links
  • Better interoperability: native desktop and mobile clients work without custom sync tooling for basic access
  • Lower deployment friction: Docker Compose, environment-based configuration, Helm chart, and Nix module

OxiCloud is not trying to mirror the full plugin ecosystem of Nextcloud. It is designed for a smaller stack, fast startup, and standards-based interoperability.

Quick Start

Docker Compose

Requires Docker and Docker Compose.

git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env

# If users will access OxiCloud through a domain or reverse proxy,
# set OXICLOUD_BASE_URL in .env before the first login.
docker compose up -d

Open http://localhost:8086.

Prebuilt binary

Binary releases (Linux musl amd64/arm64, macOS Intel/Apple Silicon) are attached to every tagged release on GitHub — the whole SPA + all operator subcommands + migrations bake into a single self-contained executable. See docs/install/binary.md for the download / verify / systemd walkthrough.

cargo binstall oxicloud works too once a release is out.

Run from source

Requires Rust 1.93+ and PostgreSQL.

git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env

# If PostgreSQL runs on your host instead of Docker, update both
# OXICLOUD_DB_CONNECTION_STRING and DATABASE_URL to use localhost:5432.
cargo run

Help Shape OxiCloud

If you want OxiCloud to get better faster, use the repo like a product feedback loop, not just a code dump.

The best feature ideas usually come from real deployment pain. If you hit friction, open an issue and describe the workflow you want.

Architecture and Deployment

OxiCloud follows a clean, hexagonal architecture so protocol handlers, business logic, and infrastructure stay separated.

  • Backend: Rust + Axum
  • Database: PostgreSQL
  • Configuration: environment variables
  • Default deployment: Docker Compose
  • Additional packaging: Helm chart and Nix module

Architecture docs: internal architecture · caching architecture · database transactions · storage safety

Configuration and Integrations

Start with example.env. The most important settings are:

  • OXICLOUD_BASE_URL for reverse proxies, domains, and external access
  • OXICLOUD_DB_CONNECTION_STRING for PostgreSQL
  • OXICLOUD_OIDC_ENABLED and related settings for SSO
  • OXICLOUD_WOPI_ENABLED and discovery URL for office editing
  • MIMALLOC_PURGE_DELAY=0 for lower idle RSS in constrained environments
