/// - dutree -
///
/// Simple command to analyse disk usage from the terminal
///
/// Usage:
/// btrfs-sync [options] <src> [<src>...] [[user@]host:]<dir>
///
/// -k|--keep NUM keep only last <NUM> sync'ed snapshots
/// -d|--delete delete snapshots in <dst> that don't exist in <src>
/// -z|--xz use xz compression. Saves bandwidth, but uses one CPU
/// -Z|--pbzip2 use pbzip2 compression. Saves bandwidth, but uses all CPUs
/// -q|--quiet don't display progress
/// -v|--verbose display more information
/// -h|--help show usage
///
/// <src> can either be a single snapshot, or a folder containing snapshots
/// <user> requires privileged permissions at <host> for the 'btrfs' command
///
/// Cron example: daily synchronization over the internet, keep only last 50
///
/// cat > /etc/cron.daily/btrfs-sync <<EOF
/// #!/bin/bash
/// /usr/local/sbin/btrfs-sync -q -k50 -z /home user@host:/path/to/snaps
/// EOF
/// chmod +x /etc/cron.daily/btrfs-sync
