 Basically, my laptop is configured to save 24 hourly snapshots, 7 daily snapshots, 4 weekly snapshots. The external backup drive has 6 months of snapshots.  Basically, my laptop is configured to save 24 hourly snapshots, 7 daily snapshots, 4 weekly snapshots.

-The extra ''[[ssh://127.0.0.1/mnt/home]]'' paragraph basically follows the "Example: multiple btrbk instances" on the btrbk's Github page[(btrbk_github)]. This allows ''snapshot_dir'' to get cleared up locally. If you write everything in one paragraph, then btrbk refuses to clean up snapshots, because external hard drives are not connected. If you write another paragraph of ''volume /mnt/home'', then btrbk complains that the two snapshots are created at the same directory. +The extra ''[[ssh://127.0.0.1/mnt/home]]'' paragraph basically follows the "Example: multiple btrbk instances" on the btrbk's Github page[(btrbk_github)].

If you write another paragraph of ''volume /mnt/home'', then btrbk complains that the two snapshots are created at the same directory. The side effect of that is the funny ''ssh'', ''sshd'', ''btrfs-send'', ''btrfs-receive'' CPU usage, when sending snapshot to external drives
