# xbackup

This is a convenience wrapper around the Borg backup tool.


## Expected Environment

This tool is designed for Arch Linux. Because it is written in Python and has
minimal dependencies it should be easy to adapt it to other Linux distributions.

These dependencies have to be installed:

- [python3][1]
- [borg][2]


## Installation

Please select the right subsection for your system.

### Arch Linux

Visit my [packaging repository ][3]
to get the build files. You can then install the software like an AUR package
following the [recommendations][4]
in the Arch Linux wiki.

### Other Linux Distributions

The Makefile of this repository will help you to install the software or create
a tar archive of a certain commit (which could be helpful for packaging).

Keep in mind, that there is no maintained way to uninstall the software via the
Makefile! The reason for that is an additional amount of work, the possibility
of bugs in the uninstall routine and the existence of package managers for Linux
which guarantee you correct uninstallation.

The Makefile of this repository contains an `install` target. Simply run

```
sudo make install
```

to install it to your system. Alternatively you can install it to a fake root
folder:

```
make DESTDIR="path/to/my/fakeroot" install
```

or create only a tar archive from this source for external packaging:

```
make tarball
```


## Usage

This section covers the main use cases addressed by xbackup.

### Configuration

Please edit the configuration file at `/etc/xbackup/config.json` before you run
the software. It contains suitable defaults for a full system backup which is
the main purpose of this script.

Using the default configuration, xbackup will include everything from the root
folder `/` blacklisting only folders which are not reasonable for a backup,
because they are virtual filesystems from the Linux kernel (like `/dev`), only
contain temporary data (like `/tmp`) or are not part of the system itself (like
`/mnt` or `/media`).

### Make a Backup

After configuration you can run the backup like this:

```
sudo xbackup backup
```

For further details run `xbackup --help`. There are options to select a
different configuration file and for a non-interactive execution which is
suitable for scripting.

### Prune your Backups

Just making backups leads to increased disk space usage. To avoid a harddrive
full of backups the Borg backup tool allows you to prune your backups. This
functionality is also wrapped by xbackup.

Edit the configuration file to select how many backups you want to keep. Then
run:

```
sudo xbackup prune
```

This will clean up the backup repository in the location specified by your
configuration file.
