Some Site Sync use cases need to expose site to another one.
For example if majority of artists work in studio, they are not using
SS at all, but if you want to expose published assets to 'studio' site

mark published assets to live on multiple sites (they might be
physically in same location - mounted shared disk).

![Configure module](assets/site_sync_system.png)
### Sites
By default there are two sites created for each OpenPype installation:
- **studio** - default site - usually a centralized mounted disk accessible to all artists. Studio site is used if Site Sync is disabled.
- **local** - each workstation or server running OpenPype Tray receives its own with unique site name. Workstation refers to itself as "local"however all other sites will see it under it's unique ID.
Artists can explore their site ID by opening OpenPype Info tool by clicking on a version number in the tray app.
Many different sites can be created and configured on the system level, and some or all can be assigned to each project.
Each OpenPype Tray app works with two sites at one time. (Sites can be the same, and no synching is done in this setup).
Sites could be configured differently per project basis.
Each new site needs to be created first in `System Settings`. Most important feature of site is its Provider, select one from already prepared Providers.
#### Alternative sites
This attribute is meant for special use cases only.
One of the use cases is sftp site vendoring (exposing) same data as regular site (studio). Each site is accessible for different audience. 'studio' for artists in a studio via shared disk, 'sftp' for externals via sftp server with mounted 'studio' drive.
Change of file status on one site actually means same change on 'alternate' site occured too. (eg. artists publish to 'studio', 'sftp' is using
same location >> file is accessible on 'sftp' site right away, no need to sync it anyhow.)
##### Example
![Configure module](assets/site_sync_system_sites.png)
Admin created new `sftp` site which is handled by `SFTP` provider. Somewhere in the studio SFTP server is deployed on a machine that has access to `studio` drive.
Alternative sites work both way:
- everything published to `studio` is accessible on a `sftp` site too
- everything published to `sftp` (most probably via artist's local disk - artists publishes locally, representation is marked to be synced to `sftp`. Immediately after it is synced, it is marked to be available on `studio` too for artists in the studio to use.)

Sites could be configured differently per project basis.
## Providers
Each site implements a so called `provider` which handles most common operations (list files, copy files etc.) and provides interface with a particular type of storage. (disk, gdrive, aws, etc.)

If a studio needs to use other services for cloud storage, or want to implement totally different storage providers, they can do so by writing their own provider plugin. We're working on a developer documentation, however, for now we recommend looking at `abstract_provider.py`and `gdrive.py` inside `openpype/modules/sync_server/providers` and using it as a template.
### Running Site Sync in background
Site Sync server synchronizes new published files from artist machine into configured remote location by default.
There might be a use case where you need to synchronize between "non-artist" sites, for example between studio site and cloud. In this case
you need to run Site Sync as a background process from a command line (via service etc) 24/7.
To configure all sites where all published files should be synced eventually you need to configure `project_settings/global/sync_server/config/always_accessible_on` property in Settins (per project) first.
![Set another non artist remote site](assets/site_sync_always_on.png)
This is an example of:
- Site Sync is enabled for a project
- default active and remote sites are set to `studio` - eg. standard process: everyone is working in a studio, publishing to shared location etc.
- (but this also allows any of the artists to work remotely, they would change their active site in their own Local Settings to `local` and configure local root.
This would result in everything artist publishes is saved first onto his local folder AND synchronized to `studio` site eventually.)
- everything exported must also be eventually uploaded to `sftp` site
This eventual synchronization between `studio` and `sftp` sites must be physically handled by background process.
As current implementation relies heavily on Settings and Local Settings, background process for a specific site ('studio' for example) must be configured via Tray first to `syncserver` command to work.
To do this:
- run OP `Tray` with environment variable OPENPYPE_LOCAL_ID set to name of active (source) site. In most use cases it would be studio (for cases of backups of everything published to studio site to different cloud site etc.)
- start `Tray`
- check `Local ID` in information dialog after clicking on version number in the Tray
- open `Local Settings` in the `Tray`
- configure for each project necessary active site and remote site
- close `Tray`
- run OP from a command line with `syncserver` and `--active_site` arguments
This is an example how to trigger background synching process where active (source) site is `studio`.
(It is expected that OP is installed on a machine, `openpype_console` is on PATH. If not, add full path to executable.
)
```shell
openpype_console syncserver --active_site studio
```
