+
+#### Using Google Cloud Storage
+If you want to deploy PrivateBin in a serverless manner in the Google Cloud, you
+can choose the `GoogleCloudStorage` as backend. To use this backend, you create
+a GCS bucket and specify the name as the model option `bucket`. Alternatively,
+you can set the name through the environment variable `PRIVATEBIN_GCS_BUCKET`.
+
+The default prefix for pastes stored in the bucket is `pastes`. To change the
+prefix, specify the option `prefix`.
+
+Google Cloud Storage buckets may be significantly slower than a `FileSystem` or
+`Database` backend. The big advantage is that the deployment on Google Cloud
+Platform using Google Cloud Run is easy and cheap.
+
+To use the Google Cloud Storage backend you have to install the suggested
+library using the command `composer require google/cloud-storage`.
+
+#### Using S3 Storage
+Similar to Google Cloud Storage, you can choose S3 as storage backend. It uses
+the AWS SDK for PHP, but can also talk to a Rados gateway as part of a CEPH
+cluster. To use this backend, you first have to install the SDK in the
+document root of PrivateBin: `composer require aws/aws-sdk-php`. You have to
+create the S3 bucket on the CEPH cluster before using the S3 backend.
+
+In the `[model]` section of cfg/conf.php, set `class` to `S3Storage`.
+
+You can set any combination of the following options in the `[model_options]`
+section:
+
+  * region
+  * version
+  * endpoint
+  * bucket
+  * prefix
+  * accesskey
+  * secretkey
+  * use_path_style_endpoint
+
+By default, prefix is empty. If set, the S3 backend will place all PrivateBin
+data beneath this prefix.
+
+For AWS, you have to provide at least `region`, `bucket`, `accesskey`, and
+`secretkey`.
+
+For CEPH, follow this example:
+
+```
+region = ""
+version = "2006-03-01"
+endpoint = "https://s3.my-ceph.invalid"
+use_path_style_endpoint = true
+bucket = "my-bucket"
+accesskey = "my-rados-user"
+secretkey = "my-rados-pass"

+/**
+ * S3.php
+ *
+ * an S3 compatible data backend for PrivateBin with CEPH/RadosGW in mind
+ * see https://docs.ceph.com/en/latest/radosgw/s3/php/
+ * based on lib/Data/GoogleCloudStorage.php from PrivateBin version 1.5.0
+ *
+ * @link      https://github.com/PrivateBin/PrivateBin
+ * @copyright 2022 Felix J. Ogris (https://ogris.de/)
+ * @license   https://www.opensource.org/licenses/zlib-license.php The zlib/libpng License
+ * @version   1.4.1
+ *
+ * Installation:
+ *   1. Make sure you have composer.lock and composer.json in the document root of your PasteBin
+ *   2. If not, grab a copy from https://github.com/PrivateBin/PrivateBin
+ *   3. As non-root user, install the AWS SDK for PHP:
+ *      composer require aws/aws-sdk-php
+ *      (On FreeBSD, install devel/php-composer2 prior, e.g.: make -C /usr/ports/devel/php-composer2 install clean)
+ *   4. In cfg/conf.php, comment out all [model] and [model_options] settings
+ *   5. Still in cfg/conf.php, add a new [model] section:
+ *      [model]
+ *      class = S3Storage
+ *   6. Add a new [model_options] as well, e.g. for a Rados gateway as part of your CEPH cluster:
+ *      [model_options]
+ *      region = ""
+ *      version = "2006-03-01"
+ *      endpoint = "https://s3.my-ceph.invalid"
+ *      use_path_style_endpoint = true
+ *      bucket = "my-bucket"
+ *      prefix = "privatebin"  (place all PrivateBin data beneath this prefix)
+ *      accesskey = "my-rados-user"
+ *      secretkey = "my-rados-pass"
