# Borgend

This is a retrying and queuing scheduler as well as a MacOS tray icon for [BorgBackup](https://borgbackup.readthedocs.io/en/stable/).
If you are not on MacOS, no tray icon will be displayed, but you can still use Borgend as a scheduler.

Designed with laptops in mind, Borgend works in “dreamtime”: on MacOS the scheduler discounts system sleep periods from the backup intervals. If you wish, you can also choose “realtime” scheduling.
You can have multiple backups to the same repository; for example, you may backup a small subset of your files every couple of hours, and everything once a day or once a week. Borgend will ensure that only one backup is launched at a time, and queue the other one until the repository is available.
If there was an error, such as when you are offline and backup to a remote ssh location, Borgend will also retry the backup at set shorter intervals.

The lead author is Tuomo Valkonen (<tuomov@iki.fi>).

## Installation

You will need to install the following non-standard Python packages:

 - [keyring](https://pypi.python.org/pypi/keyring) to extract passphrases from the keychain
 - [pyyaml](http://pyyaml.org/) for parse configuration files

The use the tray icon on Mac OS, you will need:

 - [rumps](https://github.com/jaredks/rumps) (Ridiculously Uncomplicated macOS Python Statusbar apps)

If you are not on Mac OS, you will need:

 - [xdg](https://pypi.python.org/pypi/xdg/3.0.0) for configuration file location

For passphrase use authentication to work correctly, it is useful to create a standalone Mac app. This can be don with `py2app`. You can install it with

    pip install py2app

(for alternatives see [py2app documentation](https://py2app.readthedocs.io/en/latest/install.html)). Then, to build the standalone app, run

    python3 setup.py py2app

The apps hould be placed under `dist/`.


## Usage and configuration

### Configuration file

See the included `config.example.yaml`, which shoud be relatively self-explanatory. Everything under `common_parameters`, `create_parameters`, and `prune_parameters` are simply Borg command line key–value parameters.
Edit the sample configuration file and copy it to its proper location. On MacOS this should be `~/Library/Application Support/borgend/config.yaml`, and on other systems `~/.config/borgend/config.yaml`. You can find the location with the `--help` option.

### Passphrases

Passphrases are stored in the OS X Keychain (or whatever the keyring package supports on other systems). In the Borgend configuration file, you only configure the ‘account’ of the of the password using `keychain_account` keyword of each backup set. The ‘service’ of the password has to be `borg-backup`. To add a password into the keychain for the ‘my-borg-backup’, you may use:

    security add-generic-password -a my-borg-backup -s borg-backup -w [PASSWORD]
