This is the script I use to backup my macbook to a borgbackup repository. It should be a drop-in script and suit most users just fine, but I do recommend looking at the values and making them fit for your specific situation.
# Setting this, so the repo does not need to be given on the commandline:
export BORG_REPO='*******'
# Setting this, so you won't be asked for your repository passphrase:
export BORG_PASSPHRASE='*******'
# some helpers and error handling:
function info () { echo -e "\n"`date` $@"\n" >&2; }
trap "echo `date` Backup interrupted >&2; exit 2" SIGINT SIGTERM
info "Starting backup"
