## Install
To install the program, first clone the repository:
For Arch Linux and Arch-based distros, two packages are available in the AUR (aur.archlinux.org):
- **simple_backup** for the release version
- **simple_backup-git** for the git version
To install it from source, first clone the repository:
```bash
git clone https://git.shouldnt.work/fuxino/simple_backup.git
```
Then install the tools required to build the package:
```bash
pip install --upgrade build
```
Finally, run:
Then build the package (this requires the Python `build` module, e.g. the python-build package on Arch Linux):
```bash
cd simple_backup
python -m build --wheel
python -m pip install dist/*.whl
```
For Arch Linux and Arch-based distros, two packages are available in the AUR (aur.archlinux.org):
- **simple_backup** for the release version
- **simple_backup-git** for the git version
Many distributions don't allow installing packages with pip into the system Python ("externally-managed-environment" error).
In that case, install the wheel in a virtual environment, for example with pipx:
```bash
pipx install dist/*.whl
```
Optional dependencies can be installed as extras, for example `pipx install 'dist/simple_backup-<version>-py3-none-any.whl[REMOTE]'` (available extras: JOURNAL, NOTIFICATIONS, REMOTE).
## Running as root
To back up files that your user can't read, run simple_backup with sudo or doas.
In that case the user who ran the command is detected automatically, so that '~' (in the inputs and in the default configuration file path) refers to that user's home directory, not root's.
When running as root in other ways (e.g. from a systemd service), specify the user with the --user (or -u) argument.
## Old backups
The number of old backups to keep can be set with the --keep (or -k) argument (or in the configuration file).

It's possible to use a remote server as destination for the backup. Just use the --ssh-user and --ssh-host arguments (or set them in the configuration file).
Both are required: if only one of them is set, simple_backup exits with an error.
For this to work, rsync must be installed on the server too.
The output directory is a path on the server. A leading '~' and relative paths refer to the user's home directory on the server.
On the command line, quote '~' so that your local shell doesn't expand it:
```bash
simple_backup --ssh-host server --ssh-user user -o '~/backups'
```
### Server authentication
The best way to handle the authentication is to have an ssh agent running on your system, otherwise if a passphrase is necessary to unlock the ssh key, it will be necessary to enter it more than once.
If needed, it's possible to specify the ssh key location with the --keyfile argument or in the configuration file.
