=== Caching ===
=== Data storage ===
 
Nextcloud stores metadata in the database and files either on a local filesystem, external storage, or in an object storage.
[[Redis]] can be enabled as a performant caching backend using following configuration. This will bring faster page loads to your Nextcloud instance.
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
services.nextcloud = {               
  enable = true;       
  configureRedis = true;
  [...]
};
</nowiki>}}


Note that APCu will still be used for local caching, as recommended by Nextcloud upstream.
==== Local filesystem ====
Using a filesystem with snapshot support, such as btrfs or zfs, may be useful for backup purposes


=== Object store ===
==== External storage ====
https://docs.nextcloud.com/server/stable/admin_manual/configuration_files/external_storage_configuration_gui.html


==== Object store ====
In this example we'll configure a local S3-compatible object store using Minio and connect it to Nextcloud

=== Migration ===
If you want to migrate your Nextcloud instance from one place to another, keep in mind:
* Distribution-agnostic instructions are at https://docs.nextcloud.com/server/stable/admin_manual/maintenance/migrating.html
* You can use the [https://search.nixos.org/options?show=services.nextcloud.secretFile services.nextcloud.secretFile] option to set secrets. Notably you'll likely want to inherit the following values from your old to your new instance:
** [https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/config_sample_php_parameters.html#instanceid instanceid]
** [https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/config_sample_php_parameters.html#passwordsalt passwordsalt]
** [https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/config_sample_php_parameters.html#secret secret]
* To be able to configure TLS for your new instance before you've updated your DNS record, you can use [[ACME#DNS challenge|ACME DNS Challenge]]. Don't forget to clear <code>acmeRoot</code>:
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
services.nginx.virtualHosts.${config.services.nextcloud.hostName} = {
  forceSSL = true;
  enableACME = true;
  # force DNS-01 validation
  acmeRoot = null;
};
</nowiki>}}
=== Backups ===
You should make backups of both the database and your storage.
For the database, [https://search.nixos.org/options?show=services.mysqlBackup services.mysqlBackup] or [https://search.nixos.org/options?show=services.postgresqlBackup services.postgresqlBackup] may come in handy. For local storage backups, periodically taking a snapshot of a snapshot-enabled filesystem such as btrfs or zfs may be a good first step. Remember to also make off-site copies.

=== Enable Two-factor authentication ===
Two-factor authentication can be enabled for your server via the administration interface in your browser. There is no way to declare this setting via nix configuration, so you should follow the [https://docs.nextcloud.com/server/latest/admin_manual/configuration_user/two_factor-auth.html official documentation] to set up Two-factor authentication.


=== Enable HEIC image preview ===
=== Enable HEIC image preview ===


HEIC image preview needs to be explicitly enabled. This is done by adjusting the <code>enabledPreviewProviders</code> option. Beside the default list of supported formats, add an additional line <code>"OC\\Preview\\HEIC"</code> for HEIC image support.

Due to https://github.com/ONLYOFFICE/onlyoffice-nextcloud/issues/931 you need to apply the workaround from https://github.com/NixOS/nixpkgs/pull/338794.
Install the onlyoffice documentserver as described in [[ONLYOFFICE_DocumentServer]].


Then point the app to the document server from within the Nextcloud UI ("Administration Settings" -> Administration -> ONLYOFFICE), and make sure the 'services.onlyoffice.jwtSecretFile points to a file containing the same key as entered in the configuration of the Nextcloud app.

For easy deployment, there's the [https://apps.nextcloud.com/apps/richdocumentscode richdocumentscode app] which bundles the CODE server. While being less performant than a standalone deployment of the CODE server, this solution does not require an additional service to be deployed and managed externally from NextCloud. Unfortunately the richdocumentscode app bundles the CODE server as an AppImage and therefore does not work out of the box on NixOS. Follow https://github.com/NixOS/nixpkgs/issues/339798 if you want to get informed about packaging progress. Also CODE standalone is currently not packaged in nixpkgs (https://github.com/NixOS/nixpkgs/issues/218878).

=== Memories ===
To enable hardware acceleration, nextcloud will need access to the graphics card with e.g:<syntaxhighlight lang="nix">
  users.users.nextcloud.extraGroups = [ "video" ];
  systemd.services.phpfpm-nextcloud.serviceConfig = {
    DeviceAllow = "/dev/dri/renderD128 rw";
    PrivateDevices = lib.mkForce false;
  };
</syntaxhighlight>You will still need to enable the relevant app configuration through "Administration Settings > Memories > HW Acceleration".
