 ## 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"`).

-happen automatically.
-
-Otherwise, if you see an error similar to `The following signatures were invalid: EXPKEYSIG F473DD4473365DE1`, you

-removing the experimental support for it in this release.
-
-The `experimental_features.msc3886_endpoint` configuration option has
-been removed.
-
-## Authenticated media is now enforced by default
-
-The [`enable_authenticated_media`] configuration option now defaults to true.
-
-This means that clients and remote (federated) homeservers now need to use
-the authenticated media endpoints in order to download media from your
-homeserver.
-
-As an exception, existing media that was stored on the server prior to
-this option changing to `true` will still be accessible over the

-# 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.
