 #### SSE-C encryption (since Garage v1.0)
 Since version 1.0, Garage supports server-side encryption with customer keys
 (SSE-C).  In this mode, Garage is responsible for encrypting and decrypting
 objects, but it does not store the encryption key itself. The encryption key
 should be provided by Nextcloud upon each request.  This mode of operation is
 supported by Nextcloud and it has successfully been tested together with
 Garage.
 To enable SSE-C encryption:
 1. Make sure your Garage server is accessible via SSL through a reverse proxy
   such as Nginx, and that it is using a valid public certificate (Nextcloud
   might be able to connect to an S3 server that is using a self-signed
   certificate, but you will lose many hours while trying, so don't).
   Configure values for `use_ssl` and `port` accordingly in your `config.php`
   file.
 2. Generate an encryption key using the following command:
    ```
    openssl rand -base64 32
    ```
    Make sure to keep this key **secret**!
 3. Add the encryption key in your `config.php` file as follows:
    ```php
    <?php
    $CONFIG = array(
    'objectstore' => [
        'class' => '\\OC\\Files\\ObjectStore\\S3',
        'arguments' => [
            ...
            'sse_c_key' => 'exampleencryptionkeyLbU+5fKYQcVoqnn+RaIOXgo=',
            ...
        ],
    ],
    ```
 Nextcloud will now make Garage encrypt files at rest in the storage bucket.
 These files will not be readable by an S3 client that has credentials to the
 bucket but doesn't also know the secret encryption key.

 an encryption mode of Amazon S3 where data is encrypted at rest using
 encryption keys given by the client.  The encryption keys are passed to the
 server in a header in each request, to encrypt or decrypt data at the moment of
 reading or writing. The server discards the key as soon as it has finished
 using it for the request.  This mode allows the data to be encrypted at rest by
 Garage itself, but it requires support in the client software. It is also not
 adapted to a model where the server is not trusted or assumed to be
 compromised, as the server can easily know the encryption keys.  Note however
 that when using SSE-C encryption, the only Garage node that knows the
 encryption key passed in a given request is the node to which the request is
 directed (which can be a gateway node), so it is easy to have untrusted nodes
 in the cluster as long as S3 API requests containing SSE-C encryption keys are
 not directed to them.
 Implementing automatic data encryption directly in Garage without client-side
 management of keys (something like
 [SSE-S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingServerSideEncryption.html))
 could make things simpler for end users that don't want to setup LUKS, but also
 raises many more questions, especially around key management: for encryption of
 data, where could Garage get the encryption keys from? If we encrypt data but
 keep the keys in a plaintext file next to them, it's useless. We probably don't
 want to have to manage secrets in Garage as it would be very hard to do in a
 secure way. At the time of speaking, there are no plans to implement this in
 Garage.

 **Make sure `replication_factor` is the same in the configuration files of all nodes.
 Never run a Garage cluster where that is not the case.**
 It is technically possible to change the replication factor although it's a
 dangerous operation that is not officially supported.  This requires you to
 delete the existing cluster layout and create a new layout from scratch,
 meaning that a full rebalancing of your cluster's data will be needed.  To do
 it, shut down your cluster entirely, delete the `custer_layout` files in the
 meta directories of all your nodes, update all your configuration files with
 the new `replication_factor` parameter, restart your cluster, and then create a
 new layout with all the nodes you want to keep.  Rebalancing data will take
 some time, and data might temporarily appear unavailable to your users.
 It is recommended to shut down public access to the cluster while rebalancing
 is in progress.  In theory, no data should be lost as rebalancing is a
 routine operation for Garage, although we cannot guarantee you that everything
 will go right in such an extreme scenario.

  - Replication factor `2`, consistency mode `degraded`: While this mode
    technically exists, its properties are the same as with consistency mode `consistent`,
    since the read quorum with replication factor `2`, consistency mode `consistent` is already 1.
  - Replication factor `2`, consistency mode `dangerous`: written objects are written to
    the second replica asynchronously. This means that Garage will return `200
    OK` to a PutObject request before the second copy is fully written (or even

 Changing the `replication_mode` between modes with the same number of replicas
 (e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
 just changing the `replication_mode` parameter in your config files and restarting all your
 Garage nodes.
 It is also technically possible to change the replication mode to a mode with a

 title = "Migrating from 0.9 to 1.0"
 weight = 11
 +++
 **This guide explains how to migrate to 1.0 if you have an existing 0.9 cluster.
 We don't recommend trying to migrate to 1.0 directly from 0.8 or older.**
 This migration procedure has been tested on several clusters without issues.
 However, it is still a *critical procedure* that might cause issues.
 **Make sure to back up all your data before attempting it!**
 You might also want to read our [general documentation on upgrading Garage](@/documentation/operations/upgrading.md).
 ## Changes introduced in v1.0
 The following are **breaking changes** in Garage v1.0 that require your attention when migrating:
 - The Sled metadata db engine has been **removed**. If your cluster was still
  using Sled, you will need to **use a Garage v0.9.x binary** to convert the
  database using the `garage convert-db` subcommand. See
  [here](@/documentation/reference-manual/configuration.md#db_engine) for the
  details of the procedure.
 The following syntax changes have been made to the configuration file:
 - The `replication_mode` parameter has been split into two parameters:
  [`replication_factor`](@/documentation/reference-manual/configuration.md#replication_factor)
  and
  [`consistency_mode`](@/documentation/reference-manual/configuration.md#consistency_mode).
  The old syntax using `replication_mode` is still supported for legacy
  reasons and can still be used.
 - The parameters `sled_cache_capacity` and `sled_flush_every_ms` have been removed.
 ## Migration procedure
 The migration to Garage v1.0 can be done with almost no downtime,
 by restarting all nodes at once in the new version.
 The migration steps are as follows:
 1. Do a `garage repair --all-nodes --yes tables`, check the logs and check that
   all data seems to be synced correctly between nodes. If you have time, do
   additional `garage repair` procedures (`blocks`, `versions`, `block_refs`,
   etc.)
 2. Ensure you have a snapshot of your Garage installation that you can restore
   to in case the upgrade goes wrong:
   - If you are running Garage v0.9.4 or later, use the `garage meta snapshot
     --all` to make a backup snapshot of the metadata directories of your nodes
     for backup purposes, and save a copy of the following files in the
     metadata directories of your nodes: `cluster_layout`, `data_layout`,
     `node_key`, `node_key.pub`.
   - If you are running a filesystem such as ZFS or BTRFS that support
     snapshotting, you can create a filesystem-level snapshot to be used as a
     restoration point if needed.
   - In other cases, make a backup using the old procedure: turn off each node
     individually; back up its metadata folder (for instance, use the following
     command if your metadata directory is `/var/lib/garage/meta`: `cd
     /var/lib/garage ; tar -acf meta-v0.9.tar.zst meta/`); turn it back on
     again.  This will allow you to take a backup of all nodes without
     impacting global cluster availability.  You can do all nodes of a single
     zone at once as this does not impact the availability of Garage.
 3. Prepare your updated binaries and configuration files for Garage v1.0
 4. Shut down all v0.9 nodes simultaneously, and restart them all simultaneously
   in v1.0.  Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to
   achieve this as fast as possible.  Garage v1.0 should be in a working state
   as soon as enough nodes have started.
 5. Monitor your cluster in the following hours to see if it works well under
   your production load.

         this flag set either 1. make our executables crash or 2. compile as dynamic on some platforms.
         Here, we deactivate it. Later (find `codegenOpts`), we reactivate it for supported targets
         (only amd64 curently) through the `-static-pie` flag.
         PIE is a feature used by ASLR, which helps mitigate security issues.
