# Storage
|
|
|
|
PicHost supports **local disk** and **S3-compatible object storage** (Cloudflare R2, Tencent COS, Alibaba OSS, AWS S3, etc.). Admins manage backends at **Storage** (`/storage`); new uploads go to the **default** backend.
|
|
|
|
|
|
|
|
## Layout (local)
|
|
|
|
```
|
|
/data
|
|
├── pichost.db # SQLite: users, sessions, settings, storage_backends, images index
|
|
└── images/ # All files when using local backend
|
|
```
|
|
|
|
- New uploads: `images/randomId.webp` or `images/YYYY/MM/randomId.webp` (flat mode in Settings)
|
|
- Migrated legacy: `images/blog/...` and similar
|
|
- With cloud backends, blobs live in the bucket; index stays in SQLite `images`
|
|
|
|
All **keys** start with `images/`. The upload API does **not** accept a `folder` parameter.
|
|
|
|
## Adding a backend
|
|
|
|
1. Sign in as admin → **Storage** → **Add backend**.
|
|
2. Choose **local disk** or **S3-compatible** (R2 / COS / OSS presets).
|
|
3. Enter connection details (bucket, endpoint, keys).
|
|
4. **Set as default** so new uploads use it.
|
|
|
|
### Cloudflare R2
|
|
|
|
| Field | Value |
|
|
| ----- | ----- |
|
|
| Endpoint | `https://<account_id>.r2.cloudflarestorage.com` |
|
|
| Region | `auto` |
|
|
| Bucket | Your R2 bucket name |
|
|
| Keys | R2 API token access / secret |
|
|
|
|
The **cloudflare** branch streamlines R2-only deploys; see branch notes on the [docs overview](./index.md).
|
|
|
|
### Environment variables (optional)
|
|
|
|
Some installs seed a default S3 backend via `STORAGE_BACKEND=s3`, `S3_ENDPOINT`, `S3_BUCKET`, `S3_ACCESS_KEY`, `S3_SECRET_KEY`, `S3_REGION`. **UI-configured backends live in SQLite** alongside env-based defaults.
|
|
|
|
## URL modes
|
|
|
|
| Mode | Behavior |
|
|
| ---- | -------- |
|
|
| **proxy** | Serve via PicHost (`GET /images/...`) |
|
|
| **public** | 302 redirect to bucket/CDN public URL |
|
|
|
|
Copied links use **IMAGE_BASE_URL**. “Hide folder prefix” may shorten URLs; the server resolves by path or basename.
|
|
|
|
## Usage & gallery filter
|
|
|
|
- Per-backend usage on the Storage page
|
|
- Gallery filter by backend (admin)
|
|
|
|
## Backup
|
|
|
|
Back up `data/images/`, `data/pichost.db`, and bucket objects.
|
|
|
|
Upgrading from v1.1.x with parallel folders: [v1.2 migration](./migration.md).
