## restic-backup.sh

> This script is my very simple take on how to perform restic backups.

First you need to download the script from this Git repository. I usually just put it in root's home.

```bash
# Download
sudo curl -o /root/restic_backup.sh https://git.socialnerds.org/david/scripts/raw/branch/main/restic_backup.sh
sudo chmod +x /root/restic_backup.sh
```

In the config section at the top of the script you can change various options to your liking.

```bash
# ****  CONFIG  ****
PASSWORD="/root/.restic-password"
REPO="sftp:<remote-server>:/path/to/repository"
KEEP=30
BIN="/usr/bin/restic"
OPTIONS="-p $PASSWORD -r $REPO -q"
```

You can run `restic_backup.sh` directly from the command line

```bash
# Usage
/root/restic_backup.sh /local/path <additional flags for the backup subcommand>

# Example
/root/restic_backup.sh /home -x -e ./.snapshots
```

or using cron.

```bash
# Cronjob
47 0 * * * /root/restic_backup.sh /home

# Cronjob (with healthchecks notification)
47 0 * * * /root/restic_backup.sh /home && curl -fsS -m 10 --retry 5 -o /dev/null https://checks.socialnerds.org/ping/fb721aec-5179-42c3-3455-4fd2ff39ii55
```

Happy backuping! :-)

## restic-repos.sh

## btrfs-snapshots.sh

## odroid-fancontrol.sh

## lib.sh

## template.sh

Use this as a base for new scripts, it already has the essentials.
```sh
# Load lib.sh
SCRIPT_LIB="lib.sh"
SCRIPT_PATH=$(readlink -f "$0")
SCRIPT_DIR=$(dirname "$SCRIPT_PATH")
if [[ -r "$SCRIPT_DIR/$SCRIPT_LIB" ]]; then
  source "$SCRIPT_DIR/$SCRIPT_LIB"
  lib_print "Loading version $LIB_GREEN_BOLD$LIB_VERSION$LIB_CLEAR of $LIB_GREEN_BOLD$LIB_NAME$LIB_CLEAR"
else
  echo "Error: Cannot load library file [$SCRIPT_DIR/$SCRIPT_LIB]"
  exit 1
fi
```

## watch-containers.sh

Simple healthchecks script to monitor running containers.

## switch-desktop.sh

I think this is only useful with ElementaryOS. I use(d) this with a hot corner to control desktops with the mouse.
