| Borgmatic Setup Tool | If you plan to use borg as backup solution, you should also take a look at [borgmatic](https://torsion.org/borgmatic/). It's a Python wrapper for the award winning backup tool [borgbackup](https://borgbackup.readthedocs.io/en/stable/index.html) that simplifies creating secure and reliable backups even more. You can even store your configurations in files. This script will do the setup for you to. | [MIT]([LICENSE](https://git.zion-networks.de/ZionNetworks/linux-bash-scripts/src/branch/main/LICENSE)) | [bormatic_setup.sh](https://git.zion-networks.de/ZionNetworks/linux-bash-scripts/src/branch/main/borgmatic_setup.sh) |
