## Disclaimer

- **This is NOT the [official sync service](https://obsidian.md/sync) provided by Obsidian.**

## !!!Caution!!!

As of Jan 2022, the plugin is considered in BETA stage. **DO NOT USE IT for any serious vaults.** **ALWAYS, ALWAYS, backup your vault before using this plugin.**

## Features

- Supports:
  - Amazon S3 or S3-compatible
  - Dropbox
  - OneDrive for personal
  - Webdav
- **Obsidiain Mobile supported.** Vaults can be synced across mobile and desktop devices with the cloud service as the "broker".
- **[End-to-end encryption](./docs/encryption.md) supported.** Files would be encrypted using openssl format before being sent to the cloud **if** user specify a password.
- **Scheduled auto sync supported.**
- **[Minimal Intrusive](./docs/minimal_intrusive_design.md).**
- **Fully open source under [Apache-2.0 License](./LICENSE).**
- **[Sync Algorithm open](./docs/sync_algorithm.md) for discussion.**

## Limitations

- **Users have to trigger the sync manually.** This design is intentional because the plugin is in beta, and it's better for users to be exactly aware of the running of this plugin.
- **"deletion" operation can only be triggered from local device.** It's because of the "[minimal intrusive design](./docs/minimal_intrusive_design.md)". May be changed in the future.
- **No Conflict resolution. No content-diff-and-patch algorithm.** All files and folders are compared using their local and remote "last modified time" and those with later "last modified time" wins.
- **Cloud services cost you money.** Always be aware of the costs and pricing.
- **All files or folder starting with `.` (dot) or `_` (underscore) are treated as hidden files, and would NOT be synced.** It's useful if you have some files just staying locally. But this strategy also means that themes / other plugins / settings of this plugin would neither be synced.

## Usage

### S3

- Prepare your S3 (-compatible) service information: [endpoint, region](https://docs.aws.amazon.com/general/latest/gr/s3.html), [access key id, secret access key](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/getting-your-credentials.html), bucket name. The bucket should be empty and solely for syncing a vault.
- Configure (enable) [CORS](https://docs.aws.amazon.com/AmazonS3/latest/userguide/enabling-cors-examples.html) for requests from `app://obsidian.md` and `capacitor://localhost` and `http://localhost`. It's unfortunately required, because the plugin sends requests from a browser-like envirement. And those addresses are tested and found on desktop and ios and android.
- Download and enable this plugin.
- Enter your information to the settings of this plugin.
- If you want to enable end-to-end encryption, also set a password in settings. If you do not specify a password, the files and folders are synced in plain, original content to the cloud.
- Click the new "circle arrow" icon on the ribbon (the left sidebar), **every time** you want to sync your vault between local and remote. (Or, you could configure auto sync in the settings panel (See next chapter).) While syncing, the icon becomes "two half-circle arrows".
- **Be patient while syncing.** Especially in the first-time sync.

### Dropbox

- **This plugin's function for Dropbox is not as mature as functions for S3.**
- **This plugin is NOT an official Dropbox product.** The plugin just uses Dropbox's public API.
- After the authorization, the plugin can read your name and email (which cannot be unselected on Dropbox api), and read and write files in your Dropbox's `/Apps/remotely-save` folder.
- If you decide to authorize this plugin to connect to Dropbox, please go to plugin's settings, and choose Dropbox then follow the instructions.
- Password-based end-to-end encryption is also supported. But please be aware that **the vault name itself is not encrypted**.

### OneDrive for personal

- **This plugin's function for OneDrive is not as mature as functions for S3.**
- **This plugin is NOT an official Microsoft / OneDrive product.** The plugin just uses Microsoft's [OneDrive's public API](https://docs.microsoft.com/en-us/onedrive/developer/rest-api).
- This plugin only works for "OneDrive for personal", and not works for "OneDrive for Business" (yet). See [#11](https://github.com/fyears/remotely-save/issues/11) to further details.
- After the authorization, the plugin can read your name and email, and read and write files in your OneDrive's `/Apps/remotely-save` folder.
- If you decide to authorize this plugin to connect to OneDrive, please go to plugin's settings, and choose OneDrive then follow the instructions.
- Password-based end-to-end encryption is also supported. But please be aware that **the vault name itself is not encrypted**.

### webdav

- **webdav support is considered experimental.**
- Currently only supports BASIC authorization method.
- Currently webdav server has to be enabled CORS for requests from `app://obsidian.md` and `capacitor://localhost` and `http://localhost`, **AND** all webdav HTTP methods, **AND** all webdav headers. These are required, because Obsidian mobile works like a browser and mobile plugins are limited by CORS policies.
  - Popular software NextCloud, OwnCloud, `rclone serve webdav` do **NOT** enable CORS by default. If you are using any of them, you should evaluate the risk, and find a way to enable CORS, before using this plugin.
  - The plugin is tested successfully under python package [`wsgidav` (version 4.0)](https://github.com/mar10/wsgidav). See [this issue](https://github.com/mar10/wsgidav/issues/239) for some details.
- Your data would be synced to a `${vaultName}` sub folder on your webdav server.
- Password-based end-to-end encryption is also supported. But please be aware that **the vault name itself is not encrypted**.

## Scheduled Auto Sync

- You can configure auto syncing every N minutes in settings.
- In auto sync mode, if any error occurs, the plugin would **fail silently**.
- Auto sync only works when Obsidian is being opened. It's **technically impossible** to auto sync while Obsidian is in background, because the plugin just works in the browser environment provided by Obsidian.
