 ## Worker Service Examples in Docker Compose
 
 In order to start the Synapse container as a worker, you must specify an `entrypoint` that loads both the `homeserver.yaml` and the configuration for the worker (`synapse-generic-worker-1.yaml` in the example below). You must also include the worker type in the environment variable `SYNAPSE_WORKER` or alternatively pass `-m synapse.app.generic_worker` as part of the `entrypoint` after `"/start.py", "run"`).

+## Redact all the events of a user
+
+This endpoint allows an admin to redact the events of a given user. There are no restrictions on redactions for a 
+local user. By default, we puppet the user who sent the message to redact it themselves. Redactions for non-local users are issued using the admin user, and will fail in rooms where the admin user is not admin/does not have the specified power level to issue redactions.

+otherwise all the events in the rooms provided in the request will be redacted. 
+

+
+The following JSON body parameters are optional:
+
+- `reason` - Reason the redaction is being requested, ie "spam", "abuse", etc. This will be included in each redaction event, and be visible to users.

+##### Red Hat Enterprise Linux / Rocky Linux / Oracle Linux
+
+*Note: The term "RHEL" below refers to Red Hat Enterprise Linux, Oracle Linux and Rocky Linux. The distributions are 1:1 binary compatible.*
+
+It's recommended to use the latest Python versions.
+
+RHEL 8 in particular ships with Python 3.6 by default which is EOL and therefore no longer supported by Synapse. RHEL 9 ships with Python 3.9 which is still supported by the Python core team as of this writing. However, newer Python versions provide significant performance improvements and they're available in official distributions' repositories. Therefore it's recommended to use them.
+
+Python 3.11 and 3.12 are available for both RHEL 8 and 9.
+
+These commands should be run as root user.
+
+Install new version of Python. You only need one of these:
+```bash
+# Python 3.11
+dnf install python3.11 python3.11-devel
+```
+```bash
+# Python 3.12
+dnf install python3.12 python3.12-devel
+```
+Finally, install common prerequisites
+```bash
+dnf install libicu libicu-devel libpq5 libpq5-devel lz4 pkgconf
+dnf group install "Development Tools"
+```
+###### Using venv module instead of virtualenv command
+
+It's recommended to use Python venv module directly rather than the virtualenv command.
+* On RHEL 9, virtualenv is only available on [EPEL](https://docs.fedoraproject.org/en-US/epel/).

+# How to back up a Synapse homeserver
+
+It is critical to maintain good backups of your server, to guard against
+hardware failure as well as potential corruption due to bugs or administrator
+error.
+
+This page documents the things you will need to consider backing up as part of
+a Synapse installation.
+
+## Configuration files
+
+Keep a copy of your configuration file (`homeserver.yaml`), as well as any
+auxiliary config files it refers to such as the
+[`log_config`](../configuration/config_documentation.md#log_config) file,
+[`app_service_config_files`](../configuration/config_documentation.md#app_service_config_files).
+Often, all such config files will be kept in a single directory such as
+`/etc/synapse`, which will make this easier.
+
+## Server signing key
+
+Your server has a [signing
+key](../configuration/config_documentation.md#signing_key_path) which it uses
+to sign events and outgoing federation requests. It is easiest to back it up
+with your configuration files, but an alternative is to have Synapse create a
+new signing key if you have to restore.
+
+If you do decide to replace the signing key, you should add the old *public*
+key to
+[`old_signing_keys`](../configuration/config_documentation.md#old_signing_keys).
+
+## Database
+
+Synapse's support for SQLite is only suitable for testing purposes, so for the
+purposes of this document, we'll assume you are using
+[PostgreSQL](../../postgres.md).
+
+A full discussion of backup strategies for PostgreSQL is out of scope for this
+document; see the [PostgreSQL
+documentation](https://www.postgresql.org/docs/current/backup.html) for
+detailed information.
+
+### Synapse-specfic details
+
+ * Be very careful not to restore into a database that already has tables
+   present. At best, this will error; at worst, it will lead to subtle database
+   inconsistencies.
+
+ * The `e2e_one_time_keys_json` table should **not** be backed up, or if it is
+   backed up, should be
+   [`TRUNCATE`d](https://www.postgresql.org/docs/current/sql-truncate.html)
+   after restoring the database before Synapse is started.
+
+   [Background: restoring the database to an older backup can cause
+   used one-time-keys to be re-issued, causing subsequent [message decryption
+   errors](https://github.com/element-hq/element-meta/issues/2155). Clearing
+   all one-time-keys from the database ensures that this cannot happen, and
+   will prompt clients to generate and upload new one-time-keys.]
+
+### Quick and easy database backup and restore
+
+Typically, the easiest solution is to use `pg_dump` to take a copy of the whole
+database. We recommend `pg_dump`'s custom dump format, as it produces
+significantly smaller backup files.
+
+```shell
+sudo -u postgres pg_dump -Fc --exclude-table-data e2e_one_time_keys_json synapse > synapse.dump
+```
+
+There is no need to stop Postgres or Synapse while `pg_dump` is running: it
+will take a consistent snapshot of the databse.
+
+To restore, you will need to recreate the database as described in [Using
+Postgres](../../postgres.md#set-up-database),
+then load the dump into it with `pg_restore`:
+
+```shell
+sudo -u postgres createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse
+sudo -u postgres pg_restore -d synapse < synapse.dump
+```
+
+(If you forgot to exclude `e2e_one_time_keys_json` during `pg_dump`, remember
+to connect to the new database and `TRUNCATE e2e_one_time_keys_json;` before
+starting Synapse.)
+
+To reiterate: do **not** restore a dump over an existing database.
+
+Again, if you plan to run your homeserver at any sort of production level, we
+recommend studying the PostgreSQL documentation on backup options.
+
+## Media store
+
+Synapse keeps a copy of media uploaded by users, including avatars and message
+attachments, in its [Media
+store](../configuration/config_documentation.md#media-store).
+
+It is a directory on the local disk, containing the following directories:
+
+ * `local_content`: this is content uploaded by your local users. As a general
+   rule, you should back this up: it may represent the only copy of those
+   media files anywhere in the federation, and if they are lost, users will
+   see errors when viewing user or room avatars, and messages with attachments.
+
+ * `local_thumbnails`: "thumbnails" of images uploaded by your users. If
+   [`dynamic_thumbnails`](../configuration/config_documentation.md#dynamic_thumbnails)
+   is enabled, these will be regenerated if they are removed from the disk, and
+   there is therefore no need to back them up.
+
+   If `dynamic_thumbnails` is *not* enabled (the default): although this can
+   theoretically be regenerated from `local_content`, there is no tooling to do
+   so. We recommend that these are backed up too.
+
+ * `remote_content`: this is a cache of content that was uploaded by a user on
+    another server, and has since been requested by a user on your own server.
+
+    Typically there is no need to back up this directory: if a file in this directory
+    is removed, Synapse will attempt to fetch it again from the remote
+    server.
+
+ * `remote_thumbnails`: thumbnails of images uploaded by users on other
+    servers. As with `remote_content`, there is normally no need to back this
+    up.
+
+ * `url_cache`, `url_cache_thumbnails`: temporary caches of files downloaded
+   by the [URL previews](../../setup/installation.md#url-previews) feature.
+   These do not need to be backed up.

+
+In all cases, authenticated requests to download media will succeed, but for unauthenticated requests, this

+  * unauthenticated client or homeserver requesting local media: allowed
+  * unauthenticated client or homeserver requesting remote media: allowed as long as the media is in the cache,

+  * unauthenticated client or homeserver requesting local media:
+    allowed if the media was stored on the server whilst `enable_authenticated_media` was `False` (or in a previous Synapse version where this option did not exist);

+
+It is especially notable that media downloaded before this option existed (in older Synapse versions), or whilst this option was set to `False`,
