 ## Restic
 
-Create your key and bucket:
-
-```bash
-garage key new my-key
-garage bucket create backup
-garage bucket allow backup --read --write --key my-key
-```
-
-Then register your Key ID and Secret key in your environment:
-
-```bash
-export AWS_ACCESS_KEY_ID=GKxxx
-export AWS_SECRET_ACCESS_KEY=xxxx
-```
-
-Configure restic from environment too:
-
-```bash
-export RESTIC_REPOSITORY="s3:http://localhost:3900/backups"
-
-echo "Generated password (save it safely): $(openssl rand -base64 32)"
-export RESTIC_PASSWORD=xxx # copy paste your generated password here
-```
-
-Do not forget to save your password safely (in your password manager or print it). It will be needed to decrypt your backups.
-
-Now you can use restic:
-
-```bash
-# Initialize the bucket, must be run once
-restic init
-
-# Backup your PostgreSQL database
-# (We suppose your PostgreSQL daemon is stopped for all commands)
-restic backup /var/lib/postgresql
-
-# Show backup history
-restic snapshots
-
-# Backup again your PostgreSQL database, it will be faster as only changes will be uploaded
-restic backup /var/lib/postgresql
-
-# Show backup history (again)
-restic snapshots
-
-# Restore a backup
-# (79766175 is the ID of the snapshot you want to restore)
-mv /var/lib/postgresql /var/lib/postgresql.broken
-restic restore 79766175 --target /var/lib/postgresql

-We will see in this part how to set up a reverse proxy with [Traefik](https://docs.traefik.io/).
-
-Here is [a basic configuration file](https://doc.traefik.io/traefik/https/acme/#configuration-examples):
-
-```toml
-[entryPoints]
-  [entryPoints.web]
-    address = ":80"

-
-### Add Garage service
-
-To add Garage on Traefik you should declare a new service using its IP address (or hostname) and port:
-
-```toml
-[http.services]
-  [http.services.my_garage_service.loadBalancer]
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://xxx.xxx.xxx.xxx"
-      port = 3900
-```
-
-It's possible to declare multiple Garage servers as back-ends:
-
-```toml
-[http.services]
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://xxx.xxx.xxx.xxx"
-      port = 3900
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://yyy.yyy.yyy.yyy"
-      port = 3900
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://zzz.zzz.zzz.zzz"
-      port = 3900
-```
-
-Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
-
-```
-[http.services]
-  [http.services.my_garage_service.loadBalancer]

-      path = "/"
-      interval = "60s"
-      timeout = "5s"
-```
-
-### Adding a website
-
-To add a new website, add the following declaration to your Traefik configuration file:
-
-```toml
-[http.routers]
-  [http.routers.my_website]
-    rule = "Host(`yoururl.example.org`)"

-### Adding gzip compression
-
-Add the following configuration section [to compress response](https://doc.traefik.io/traefik/middlewares/http/compress/) using [gzip](https://developer.mozilla.org/en-US/docs/Glossary/GZip_compression) before sending them to the client:
-

-    ...
-    middlewares = ["gzip_compress"]
-    ...
-[http.middlewares]
-  [http.middlewares.gzip_compress.compress]
-```
-
-### Add caching response
-
-Traefik's caching middleware is only available on [entreprise version](https://doc.traefik.io/traefik-enterprise/middlewares/http-cache/), however the freely-available [Souin plugin](https://github.com/darkweak/souin#tr%C3%A6fik-container) can also do the job. (section to be completed)

-
-Starting with version 0.7.2, Garage introduces an optionnal feature, K2V,
-which is an alternative storage API designed to help efficiently store
-many small values in buckets (in opposition to S3 which is more designed
-to store large blobs).
-
-K2V is currently disabled at compile time in all builds, as the
-specification is still subject to changes. To build a Garage version with
-K2V, the Cargo feature flag `k2v` must be activated.  Special builds with
-the `k2v` feature flag enabled can be obtained from our download page under
-"Extra builds": such builds can be identified easily as their tag name ends
-with `-k2v` (example: `v0.7.2-k2v`).
-
-The specification of the K2V API can be found
-[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md).
-This document also includes a high-level overview of K2V's design.
-
-The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
-The AWS region used for signature calculation is always the same as the one
-defined for the S3 API in the config file.
-
-## Enabling and using K2V
-
-To enable K2V, download and run a build that has the `k2v` feature flag
-enabled, or produce one yourself. Then, add the following section to your
-configuration file:
-
-```toml
-[k2v_api]
-api_bind_addr = "<ip>:<port>"
-```
-
-Please select a port number that is not already in use by another API
-endpoint (S3 api, admin API) or by the RPC server.
-
-We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
-
-```toml
-k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
-```
-
-There is also a simple CLI utility which can be built from source in the
-following way:
-
-```sh
-git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
-cd garage/src/k2v-client
-cargo build --features cli --bin k2v-cli
-```
-
-The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
-it. There is also a short README.md in the `src/k2v-client` folder with some
-instructions.

 Amazon defines a concept of [object locking](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-lock.html) that can be achieved either through a Retention period or a Legal hold.

+# Specification of Garage's administration API
 
-The Garage administration API is accessible through a dedicated server whose
-listen address is specified in the `[admin]` section of the configuration
-file (see [configuration file
-reference](@/documentation/reference-manual/configuration.md))
 
 **WARNING.** At this point, there is no comittement to stability of the APIs described in this document.
 We will bump the version numbers prefixed to each API endpoint at each time the syntax
 or semantics change, meaning that code that relies on these endpoint will break
 when changes are introduced.
 
-The Garage administration API was introduced in version 0.7.2, this document
-does not apply to older versions of Garage.
-
 
 ## Access control
 
 The admin API uses two different tokens for acces control, that are specified in the config file's `[admin]` section:
 
-- `metrics_token`: the token for accessing the Metrics endpoint (if this token
-  is not set in the config file, the Metrics endpoint can be accessed without
-  access control);
-
-- `admin_token`: the token for accessing all of the other administration
-  endpoints (if this token is not set in the config file, access to these
-  endpoints is disabled entirely).
-
-These tokens are used as simple HTTP bearer tokens. In other words, to
-authenticate access to an admin API endpoint, add the following HTTP header
-to your request:
-
-```
-Authorization: Bearer <token>
-```
+- `metrics_token`: the token for accessing the Metrics endpoint (if this token is not set in the config file, the Metrics endpoint can be accessed without access control);
+- `admin_token`: the token for accessing all of the other administration endpoints (if this token is not set in the config file, access to these endpoints is disabled entirely).

-The field `errorDocument` is optional, if no error document is set a generic
-error message is displayed when errors happen. Conversely, if `enabled` is
-`false`, neither `indexDocument` nor `errorDocument` must be specified.
 
-In `quotas`: new values of `maxSize` and `maxObjects` must both be specified, or set to `null`

-     Here, we deactivate it. Later (find `codegenOpts`), we reactivate it for supported targets

-     As we do not want to consider the .git folder as part of the input source,
-     we ask the user (the CI often) to pass the value to Nix.
-
-     [4] We ship some parts of the code disabled by default by putting them behind a flag.
-     It speeds up the compilation (when the feature is not required) and released crates have less dependency by default (less attack surface, disk space, etc.).
-     But we want to ship these additional features when we release Garage.
-     In the end, we chose to exclude all features from debug builds while putting (all of) them in the release builds.
