Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.

Effective transpiling of ES6

After publishing my article on ECMAScript 6, some have reached out to ask how I exactly I make it all work.

I refrained from including these details on the original post because they're subject to immiment obsoletion. These tools are changing and evolving quickly, and some of these instructions are likely to become outdated in the coming months or even weeks.

The main tool

When evaluating the available transpilers, I decided to use 6to5, which has recently been renamed to Babel. I chose it based on:

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
