Sample backup script using Borg (with optional Rclone sync)

backup

#!/bin/zsh
# Backup a folder to a remote address using borg.
# To restore: borg extract $BORG_REPO::computer-and-date

set -eu

# Will need a remote server setup with Borg, and a Borg repo first.
export BORG_REPO="<user>@<host>:<borg-repo>"

# Assuming you've installed Borg with Homebrew
export BORG_REMOTE_PATH=/usr/bin/borg

# Not 100% necessary, but you can save your borg passphrase in MacOS Keychain
# security add-generic-password -a $LOGNAME -s borg-passphrase -w <your-borg-passphrase>
export BORG_PASSPHRASE=$(security find-generic-password -w -a $LOGNAME -s borg-passphrase)

# optionally include Rclone sync with configuration password
# security add-generic-password -a $LOGNAME -s rclone-configuration -w <your-rclone-configuration-password>
RCLONE_CONFIGURATION_PASSWORD=$(security find-generic-password -w -a $LOGNAME -s rclone-configuration)

/usr/local/bin/borg create -s --progress ::"$(hostname)-$(date)" ~/directory-to-backup ~/another-directory
/usr/local/bin/borg prune --keep-daily=14 --keep-monthly=6

# optionally include Rclone sync
# requires having an Rclone remote setup on your server first.
# If you haven't password protected the configuration, you can leave out the variable.
ssh user@host /bin/bash <<EOT > /dev/null
  rclone sync --config=/path/to/rclone/config <borg-repo> <rclone-remote>:<rclone-remote-dir> <<< $RCLONE_CONFIGURATION_PASSWORD
